analyzers that are the core of any measurement system, and
a single LAN-XI acquisition module of up to 6 channels.
PULSE Access is a highly competent, ‘do all’ analysis
system for both lab and field use. It can be a troubleshooting and development comparison tool, a simple structural
analysis tool – together with an impact hammer to excite
resonances – or a general basic R&D tool for where rotating
machinery varies in speed and causes issues. It is also ideal
for pass/fail quality checks, and it is a Class 1 sound level
meter.
The system is very easy to use for basic, real-time analysis
functions like FFT, synthesized CPB and overall level analysis,
and a tachometer input provides order analysis and an
RPM reference. ‘Smart Start’ – a quick, three-step start-up
guide helps new users, while a simple, icon-based interface

TIME DATA RECORDER FOR PC
TIME DATA RECORDER FOR iPad
®
Sonoscout
PULSE Time Data Recorder with a level meter
indicating overload occurrences, and coloured level history keeping track of optimal
dynamic range selection
The channel monitor allows you to see time
or frequency content and includes a tachometer RPM and RPM profile readout
Recording time data and then post-processing the results
allows you to decide the analysis parameters later and
manipulate the raw data at leisure. In circumstances such
as troubleshooting – when the exact nature of a problem
is unknown – important information in the results can
otherwise be missed due to the assumptions made when
setting up the analyzer.
Time data acquisition and post-processing can also be
essential when real-time analyses are impossible due to the
number of measurement channels required, even with the
continuing in­creases in computing power.
While recording data, the flexibility of PULSE Time Data
Re­corder allows you to transfer data to another computer
or server for post-processing and analysis. PULSE Time Data
Re­corder allows recording and analysing data on separate
computers, or combining computers into one system as a
measurement and analysis work­station, to further optimize
processing capability.
The flexibility of the LAN-XI data acquisition hardware
platform allows configuration of any recording solution
from 2 to 600+ channels, for mobile or lab-based use.
Battery- and DC-powered options combined with LAN
connection to the host PC provide maximal efficiency and
minimal test set-up time.
Post-processing is easy to perform in PULSE Reflex, our
intuitive post-processing software.

The Sonoscout App for iPad works in
combination with a wireless LAN-XI data
acquisition hardware module. This connects
to measurement transducers, a binaural
microphone headset and a vehicle CAN bus
reader, and transmits the data to the iPad –
or records directly onto an SD card
Sonoscout is an ultra-portable, multichannel, wireless NVH
recorder. It allows real-time recording validation with a
simple touch of an iPad® screen. Sonoscout continuously
displays test information such as tacho output, to maximize
confidence during testing, and brings simple control and
analysis to tasks such as comparing vehicle and data sets.
The Sonoscout system is a combination of an iPad app
and a battery-powered acquisition front end based on any
LAN-XI hardware module. This can be placed anywhere
and connects up to 12 measurement transducers, from
which it transmits data to the app for recording. A binaural
microphone headset captures cabin sound in real-time and
replays recordings immediately.
In use, Sonoscout uses GPS to track your test routes and
event markers, which can later be uploaded into Google
Earth™. Interfacing with analogue CAN bus signals from
the test vehicle allows you to display parameters such as
speed, RPM and throttle position.
For other simple analysis functions, like rotating machinery validation and benchmarking, Sonoscout is the perfect
first step. Once you are positive that data is valid, you
can export it for further analysis in PULSE Reflex, or other
post-processing software.
The system runs on iPad (iOS 9 or later) and streams data
directly to the iPad or records to the SD card on the LAN-XI
module. You can try out the full recording and analyzer
functionality for free, by downloading the app and using the
‘virtual front end’ demonstration feature.

NVH TESTING
Noise Vibration and Harsh­ness (NVH) testing is critical for
refining the human experience of vehicles, making NVH
a key vehicle area of concern, and a vital differentiator
between comparable models.
To achieve the de­sired attributes, the vehicle must be
engineered to specified NVH targets from its inception, and
subsequently validated to see that these targets are met
following the development process.
Failure to meet targets necessitates troubleshooting to
find the root cause of the problem and eliminate it in a
cost-effective manner – where cost is also measured in
terms of weight and therefore fuel economy.
For an analysis system to suit NVH testing it needs to be
portable and robust for in-vehicle use, scalable and easy to
use.
For standardized or repeated tests, real-time multianalysis gives results as soon as you have completed a
measurement. Avoiding the additional steps required for
post-processing ensures high productivity and allows you to
validate your results on-site.
Our data-centric architecture means the systems are built
around the data flow, so tests and results are documented
from start to finish. Consequently, storing, retrieving and
reporting are efficient processes that do not require additional tools or applications. Additional time can be saved
by automating report generation in whatever measurement
report format your company uses.

ORDER ANALYSIS
Recording and order analysis
In rotating and reciprocating machines, varying load
conditions and imperfections in the moving parts cause
vibrations and associated sounds. The vibrations are shaped
by the structural properties of the moving and stationary
parts of the machine.
Order analysis relates measurements to revolutions of a
rotating part, improving knowledge about machinery such
as aircraft and automotive engines, powertrains, pumps,
compressors and electric motors.
Typical uses
• Separation of rotational and structural noise and
vibration phenomena
• Identification of noise generated by rotational vibrations
• Determination of critical speeds and excited resonances
• Investigation of instabilities in rotating machinery caused
by varying load
7708, 8700, 8702, 8704
Combining Time Data Recorder and PULSE Reflex order analysis provides you with a mobile and easy to use solution for:
• Basic fixed bandwidth rotating machinery analysis
• Quick, qualitative assessment of order content
• Determination of critical speeds and resonances
• Signature analysis of machines with rotating components
• Pre-study for tracked order analysis
• Vehicle NVH benchmarking
Order analysis with and without tracking,
first and second order cut versus time and
run-up speed profile versus time
and includes powerful data preparation tools like Tachometer repair
and Autotracker creating an RPM profile when a Tacho reference signal
is not available. Powerful analysis and report tools include Colour
contour as well as order-slice extraction plots.
Real-time order analysis with tracking
Order analysis methods
• Without tracking – for analysis of lower orders and
moderate RPM slew rates, based on fixed bandwidth
frequency spectra from FFT analysis
• With tracking – for analysis of higher orders or higher
RPM slew rates, based on order and tracked resampled
FFT analysis using a tachometer as speed reference
7770-N, 7702-N, unlimited inputs
This configuration provides FFT-based order analysis as well as order
tracking on an unlimited number of channels. Order tracking is useful
when frequency smearing will compromise the FFT-based analysis, and
when:
• Higher orders are of interest
• Orders are not well separated
• RPM ranges are wide
Both methods provide spectra, 3D plots like ‘colour contour’
or ‘Campbell diagram’, individual order, and structural slices
versus RPM of one or more rotating parts. All methods
support the use of multiple tacho signals as references,
and with the Autotracker functionality it is possible to
extract the tacho signal directly from a measurement input,
for example in cases where a tacho signal is not directly
available.
All data can be tagged with process data such as
temperature, oil pressure, position, wind speed, and all
order analysis results can be shown in relation to these
auxiliary parameters.
The solution supports automatic processing of time data recording,

The solution supports automatic processing of time data recording,
and includes additional powerful pre-analysis features like spectrogram
and interactive filters. Tracked resampling and batch statistics for calculating min, max or mean of results from multiple recording files are one
of the advanced features added to the analysis and reporting tools.
• Only lower orders are of interest
• Orders are well separated
• RPM ranges are limited
• Slew rates are moderate
• Processing resources are scarce

MACHINE DIAGNOSTICS
WT-9695 Orbit Plot allows you to display the shaft displacement relative to its bearing using
the two time signals of an X-Y proximity probe pair measured by an FFT or Order analyzer
Moving parts in any rotating machine will eventually cause
annoying vibrations that ultimately lead to breakdowns
due to production and assembly tolerances, wear, and load
variation.
Machine diagnostics is the PULSE configuration for
addressing vibration problems in rotating machines. Our
tools can be used in run-up/down sessions, and combined
to diagnose multiple faults – such as performing cepstrum
analysis of order spec­tra or envelope spectra.
All analyses can be performed simul­taneously, and the
raw signals can be recorded for subsequent analysis using
the extension PULSE Time Data Recorder. Diagnostics on
transient phenomena is then performed with PULSE Time
Capture.
All data can be tagged with auxiliary parameters such as
temperature, oil pressure, posi­tion, and wind speed, and all
results shown in relation to these.

The configuration comprises Order Analysis Type 7702-N. See Order
Analysis on page 22 of this catalogue for properties and capabilities.
Any LAN-XI data acquisition hardware module is suitable for machine
diagnostics, giving from 2 to 12 input channels. Auxiliary parameter
logging requires LAN-XI module Type 3056.
BALANCING
Imbalance results from an uneven distribution of mass in a
rotor, causing vibrations that are transmitted to the bearings
and other parts of the machine. Imperfect mass distribution
can be due to material faults, design errors, manufacturing
and assembly errors, and especially faults occurring during
operation.
Reducing these vibrations achieves better performance
and more cost-effective operation, and avoids deterioration
and fatigue failure. This requires the rotor to be balanced by
adding or removing mass at certain positions.
Our system determines balance quality for single-plane
and two-plane balancing according to the ISO1940–1
standard. Multi-plane Balancing Consultant Type 7790-B
adds three- and four-plane balancing.
Balancing Consultant has an intuitive, task-oriented user
interface that leads you quickly through the necessary tasks
for set-up, measurement and reporting.
The balancing process can either be performed in situ,
where the rotor is balanced in its own bearings and
supporting structure, or by balancing the rotors in separate
balancing machines.
Trim balancing is also supported, using rotor data stored
from previous balancing sessions. This ensures fast correction of small residual imbalances in cases where balancing
has to be repeated.
Balancing FFT and tracking
7770-N3, 7702-N3, 7790-A, 2 inputs, 1 tacho input
Balancing can be based on either frequency spectra (FFT) or order
spectra (order tracking). Traditional FFT-based balancing is sufficient
in many measurement situations. However, in cases with unstable
machinery speed and/or high frequency resolution requirements, order
tracking should be used to eliminate frequency smearing and provide
more accurate results. Balancing using order tracking requires Order
Analysis Type 7702.

To guarantee the maintenance of aircraft engines and
optimize aircraft uptime, our vibration check systems
perform field verification on specific engines. Measurements
are made according to the procedures specified by the
engine manufacturer’s main­tenance manual.
Tur­bo­meca-based engine maintenance systems are
available for 22 different variants, covering Arriel, Makila,
Arrius, Turmo, Ardiden and RTM 322 engines among others.
New systems for other engine types can easily be developed
by our Customized Project Department.
All verification of vibration levels is performed in one
engine run-up, with reference to two tacho­meter signals
– one from the gas generator and one from the power
turbine (free turbine). A warning is given if level limitations
are exceeded.
Results are automatically stored in a database and
displayed in a contour plot showing frequency, speed and
level, in order to aid fault diagnosis. A report is produced
immediately, ac­cor­ding to the manufacturer’s template.

The Transducer Smart Setup app is designed to make
transducer setup as simple and automated as possible by
reading data matrix codes on Brüel & Kjær transducers and
seamlessly transferring the information to PULSE Reflex
measurements.
Using the smartphone’s camera, you can perform a quick
scan of the transducer’s data matrix to read the transducer
data and its orientation. The data matrix code also gives
you instant access to specifications, documentation and
calibration data. In addition, you can scan customized 2D
labels attached next to the transducers to read transducer
position and node ID.
For transducers without data matrix codes, the app will
recognize the transducer and its orientation and allow you
to add associated data, minimizing the risk of data entry
errors.
Projects containing the test setup are exported as .xml
files using an email account, a cloud storage service or
iTunes and uploaded to the Hardware Setup Table in PULSE
Reflex measurements. In addition, PULSE Reflex measurements recognizes which transducer is plugged into which
input connector, eliminating the need to trace cables.
The Transducer Smart Setup app is available for iOS 8.0
or newer devices (iPhone®, iPad® and iPod touch®) and is
available free from the App Store.
Scanning the data matrix code on the
transducer (transducer information and
orientation) and the label next to the

MODAL ANALYSIS
Modal analysis is vital to understand and optimize the
inherent dynamic properties and behaviour of many diverse
kinds of structures, leading to lighter, stronger and safer
constructions, less energy consumption, greater comfort and
better performance.
In modal analysis, a mathematical model of a structure’s
dynamic properties and behaviour is obtained, consisting
of a set of modal parameters, each with a mode shape and
an associated natural frequency and modal damping value.
Experimental modal analysis finds these modal parameters
by testing, and it can be performed as classical modal
analysis or operational modal analysis.
Classical modal analysis uses measured input forces and
output responses from a structure to calculate frequency
response functions, while operational modal analysis only
measures output responses, as the natural ambient and
operating forces are used as unmeasured input.
Classical modal analysis ranges from simple mobility
tests with impact hammers to multi-shaker testing of large
structures. The results are used in a vast range of applications including:
• Optimizing the dynamic properties and behaviour of
structures
• Predicting the dynamic behaviour of components and
assembled structures
• Predicting responses due to complex excitation
• Predicting effects of structural modifications
• Inclusion of modal damping in Finite Element (FE)
models
• Correlation of test models with FE models
• Updating of FE models using test results
• Damage detection and assessment

Separation testing
A single transient shock event such as a pyroshock or a
structural impact can damage components in a structural
system. Similarly, earthquakes can cause catastrophic
failures in bridges and buildings. And with any motion
input into a system, the response can be amplified by
structural resonances, increasing the damage.
Shock Response Spectrum (SRS) analysis software
computes the shock response spectrum from transients in
the time domain. It converts motion input to a set of Single
Degree of Freedom (SDOF) damped oscillator responses.
The response amplitudes of the oscillators are plotted as a
function of SDOF frequency to produce the shock response
spectrum.
The frequencies are generally logarithmically spaced,
typically with 1/n-octave spacing. The amplitudes of the
SRS are derived from the individual SDOF responses (at
user-defined frequencies) by taking the maximum response
either during the primary shock event or during the
residual response to the event. Most commonly, the overall
maximum response is used, which includes both primary
and residual responses, called ‘maximax’.
All five of the SRS models mentioned in the
ISO 18431 – 4:2007 standard are available, and with these
five SRS models and nine ordinary criteria for amplitude
calculation (shock instances), you can configure up to 45
different response types to match your requirements.

transducers.
OMA Standard
7770-N, 7753, 7760-C, unlimited inputs
In Operational Modal Analysis (OMA) only the output of
a structure is measured, using the ambient and operating
forces as unmeasured input. OMA is used instead of classical modal analysis for accurate modal identification under
actual operating conditions, and in situations where it is
difficult or impossible to artificially excite the structure.
Many civil engineering and mechanical structures are
difficult to excite artificially due to their physical size, shape
or location. Civil engineering structures are also loaded by
ambient forces such as the waves against offshore structures, the wind on buildings, and traffic on bridges, while
mechanical structures such as aircraft, vehicles, ships and
machinery exhibit self-generated vibrations during operation. In OMA, these forces that would produce erroneous
results in classical modal analysis are instead harnessed as
input forces.
As OMA can be performed in situ during normal
operation, set-up time is reduced and downtime can be
eliminated. Adding further value, our OMA systems are
also scalable, making both hardware and software easy
to upgrade. Patents protect the core technology behind
our OMA software, including the efficient and powerful
Frequency Domain Decomposition (FDD), Enhanced
Frequency Domain Decomposition (EFDD) and Curve-fit

• Stable machine speed
• Analysing lower and/or well-separated spectral components
Order Analysis Type 7702 option is recommended in cases of slight
instability and for analysing higher and close spectral components,
in order to eliminate smearing.
Operating Deflection Shapes (ODS) analysis determines
the vibration patterns of a structure under given operating
conditions. The vibration patterns are shown as animated
geometric models of the structure that display a combination of the forcing function acting on the structure and the
dynamic properties of the structure.
The forcing function depends on the operating conditions,
which for machinery can be influenced by factors such as
engine speed, load, pressure, temperature and flow. For civil
engineering structures, ambient forces from wind, waves
and traffic might also apply.

For determining the noise emissions of products, sound
power is the preferred quantity to investigate because
it measures the absolute power of a noise source independently from its acoustic environment. The three main
methods used are:
• Free field – placing the source in an acoustically open
area (free field) and determining its sound power from
sound pressure measurements
• Reverberation room – placing the source in a reverberation room (diffuse sound field) and determining its
sound power from sound pressure measurements
• Sound intensity – directly measuring the sound intensity from the source in any sound field, to determine its
sound power

Reflex Acoustic Camera used for measurement survey of ventilation system on a train
Noise Source Identification (NSI) techniques help to optimize the noise emissions of products and their components
– on vehicles, aircraft, powertools, household goods, wind
turbines and much more. Identifying the most important
sub-sources of noise in terms of position, frequency content
and sound power radiation helps decide where design
changes can most effectively reduce overall noise radiation.
Array-based NSI provides the fastest measurement
process and the highest quality results, and our range of
arrays varies enormously in size and shape to suit the task
at hand.
The three main array software applications are acoustic
holography Type 8607, beamforming Type 8608 and
spherical beamforming Type 8606, which can all be enhanced with a large number of options. All calculation and
post-processing is performed in the same user interface.
For a specific challenge, our customized project department will tailor an optimal solution, drawing on over 30
years’ experience of designing and installing hundreds of
array-based solutions. Whether the test object is a hearing
aid mounted on a test bench, a high-speed train racing
from city to city, or an aircraft flying overhead, Brüel & Kjær
can provide a complete, turnkey solution.

The enormous growth of the wind turbine industry makes
noise problems ever-more pertinent to personnel in design,
R&D and production. We continuously develop solutions to
address these new challenges, helping to optimize operation, increase product quality and simplify measurement
procedures.
A uniform methodology to ensure consistency and
accuracy in the measurement and analysis of acoustical
emissions is provided by the international standard
‘IEC 61400-11 Wind turbine generator systems: Acoustic
noise measurement’.
Brüel & Kjær supports the standard with a complete
system to determine sound power and tonality.
For manufacturers of wind turbine components, our
sound and vibration systems ensure quality control in
gearbox and generator test rigs, and our data acquisition
and analysis systems are equally suited for on-site troubleshooting, production, and R&D facilities.
Improvements in acoustical array design and calculation
algorithms have led to our current rugged, battery-operated
systems that are ideal for outdoor use and quick to set
up. Large, ground-based arrays for precision noise source
identification help researchers and blade designers locate
troublesome areas on full-scale test turbines.
In wind tunnels, array technology is widely used on scale
models, while our flat surface microphones are ideal for
blade profile investigations.

Growing focus on noise control issues combined with
the emergence of sound quality in product design makes
acoustic material testing increasingly relevant to engineers, designers and manufacturers from a broad range of
industries.
Acoustic material testing is the process for determining
the acoustic characteristics of materials in terms of absorption, reflection, impedance, ad­mittance and transmission
loss.
A range of standards covers acoustic material testing,
prescribing well-defined acoustical conditions and special
instrumentation to ensure accuracy and re­peatability.
Our complete acoustic material testing systems make
measurements on small samples according to ISO 10534-2,
ASTM E1050 and ASTM E2611-10 international standards.
They cal­cu­la­te transmission loss based on transfer matrix
representation.
Simulation software can then help to predict the impact
of specific noise control materials at an early stage in
product development, once the acoustic characteristics of
the materials are accurately known.

Measuring a vehicle’s interior and exterior noise during
operation is far simpler indoors, using large hemi-anechoic
chambers containing chassis dynamometers – as many
automotive manufacturers and sub-suppliers do. Eliminating
variables such as weather and site variations makes
measurements more reproducible, while the stationary
vehicle allows more instrumentation.
Simulation of normal pass-by noise is achieved by placing
a row of microphones alongside the test vehicle so that
there is no need to drive the test vehicle past stationary
microphones, as is standard in a conventional outdoor
pass-by measurement. Instead the vehicle is accelerated in
the same way on a chassis dynamometer.
Simultaneous recordings are taken of a tachometer signal
from the dynamometer, the vehicle’s exterior noise at all
microphone positions, and any additional vehicle parameters. Tyre noise correction then assists accurate comparisons
with field pass-by measurement results.
Smaller rooms that lack the spatial dimensions dictated
by the current ISO 362 pass-by standard are also suitable
environments for indoor pass-by testing. Even where the
required 7.5 m width from the vehicle centre-line and more
than 20 m length will not fit in an anechoic room, our
software accurately extrapolates the measurements.
The time-domain-based calculations enable Dopplereffect correction, as well as audible playback analysis with
recorded and synthesized signals – helping you to quickly
identify areas of interest.
The measurement and calculation procedure satisfies the
ISO 362 pass-by standard and is ready for the new standard
that will replace it, which will make indoor pass-by noise
testing a standard conformance test alongside field pass-by
testing.

TIME-DOMAIN SOURCE
PATH CONTRIBUTION
SPC multiple coherence method
7798-D
The SPC Multiple Coherence module allows the quick assessment of
contributions from multiple uncorrelated or partially correlated sources,
such as tyre noise in a vehicle.
Time-domain SPC
How will each component contribute to the overall sound
of a product? How can you tell where the sound is coming
from? How does it travel to where you hear it? And what
can you do to improve the sound of the vehicle?
Whether assessing the contributions of an engine on a
test bed, or identifying operational contributions on the
road, Time-domain Source Path Contribution (SPC) allows
you to assess transfer paths and contributions to quickly
evaluate the noise and vibration perceived by vehicle
occupants.
Our unique time-domain technology allows you to listen
to and compare data sets back-to-back, and assess the
effects that developments will have on the final products
through SPC models. The system can also inspect data in
the frequency domain, giving great flexibility.
Understanding how noise and vibration is transmitted
through different paths in and around the vehicle allows you
to rank contributions using various NVH methods such as
mount-stiffness and impedance matrix methods for structure-borne NVH, and source-substitution for airborne NVH.
Using data recorded in the time domain means you can
solve any potential problems during analysis from a safely
captured data set, while you are listening to or evaluating
the calculated time signals.
SPC also offers a bridge between real-world experimental
data and analytical data generated from CAE models.
Combine test and CAE results in SPC to produce hybrid
models or virtual prototypes. Use Insight to experience the
results of experiment, hybrid or purely analytical CAE-based
SPC data through interactive playback and analysis of the
results.

Demand for better fuel economy
• Leads to new and lighter engines with smaller water
passages and less damping of powertrain noise
• Requires lightweight and low-friction gearboxes with
increased gear noise and gear rattle
• Increasing use of 2- and 3-cylinder engines with inherent
imbalance
The market, however, still expects good driving performance
and superior comfort – thus increasing the challenge for
NVH engineers.
The PULSE platform provides a wide range of tools for
general powertrain NVH analysis and simulation in the
context of the whole vehicle. Our systems perform angle
domain analysis alongside other types of analysis, such as
FFT and 1/3-octave noise analysis.
The angle domain offers a different perspective on NVH
issues where the angular position of a rotating component
(often the engine crankshaft) can reveal noise sources

ELECTROACOUSTIC TESTING
Simulated free-field measurements using TSR
analysis for determining frequency response
and harmonic distortion
Manufacturers of electroacous­tic equipment such as
loudspeakers, microphones, telephones, headsets, hearing
aids and hydro­phones consistently deliver high-quality
acoustical designs by continuously inno­vating their products
and processes.
Measuring and documenting acoustical performance is a
key element in this improvement process, during both the
development and the manufacture of new products.
In the future, the ability to characterize electroacoustic
equipment using traditional performance specifications
such as frequency response, distortion, linearity, directivity,
and delay will be com­bined with a wide range of other
acoustical and vibration measurements.
Acoustic and vibration measurements such as those
performed in material testing and modal analysis are
expected to be­come an important prerequisite for continued innovation and im­prove­ment within the development
and manufacturing of electro­acoustic equipment.

Mobile conversations can take place almost anywhere
– from quiet offices to noisy outdoor environments. And
since users demand high voice quality in all situations, the
acoustic perception of devices is critical. Corded handset/
headset telephones and mobile devices alike need advanced acoustic and electronic signal processing combined
with superior design.
We offer two standardized test configurations, with one
configuration based on a telephone test head equipped
with a stand-alone mouth simulator and ear simulator.
The second configuration is based on a Head and Torso
Simulator (HATS), with an integrated mouth simulator and
one or two integrated ear simulators.
Thanks to several decades of playing an active part in
standardization within the telecommunication industry,
Brüel & Kjær is regarded as the worldwide industry reference, setting standards for telephone testing worldwide.
Our experience of providing high-quality acoustic
solutions provides us with a solid foundation from which to
develop new products for emerging telephone technologies
and markets.
Data from various measurements, which
have been produced by the telephone test
application, can be compared with measurement data imported from the previousgeneration telephone test application
