Diagnostic Audiometer AD229e
- Efficient Hearing Examinations
Audiometry
precision
The high quality of the AD229e makes it well suited
for any stationary or portable application where
diagnostic testing of air, bone and speech is performed. The time saving automatic test functions
combined with the computer interface makes the
AD229e ideal for modern healthcare environments.
The talk forward and talk back functions make
it easy to work with the AD229e, especially with
sound booth installations. Full NOAH compatibility completes the picture.

Diagnostic Audiometer AD229e
- Efficient diagnostic examinations
Auto Threshold and Békésy Master Hearing Aid
The AD229e incorporates a function
for performing threshold determination
automatically. The test procedure is based on
the Hughson-Westlake method (up 5dB, down
10dB) and conforms to ISO 8253. Desired test
frequencies may be selected freely by the user.
The Békésy Test, featuring pure tone, pulsed
tone or narrow band noise as stimuli as
well as masking with narrow band noise, is
incorporated. After testing the test results can
be recalled from the memory of the AD229e
or transferred to a PC for database storage
or printing. A buzzer is built in, allowing the
operator to be informed about test status when
doing automatic tests.
ABLB / SISI / Stenger /
Tone in Noise
As well as the pre-programmed ABLB and SISI
tests the AD229e can perform the Stenger Test
with pure tones for evaluating malingering, or
as a binaural speech test with a monophonic
speech signal. The Langenbeck ”Tone in Noise”
Test is also included.
A carrying case will
hold the AD229e
with all its accessories.
The AD229e has incorporated a 2 channel
Master Hearing Aid for hearing aid simulation.
The speech signal from the live voice
microphone is transformed directly into digital
signals, and all sound shaping filters thus work
in the digital domain ensuring high sound
quality.
Filters and Acoustic Gain can be selected
individually for each channel.
Printing
PC connectivity provides options for data
storage and full page reports via NOAH or the
Interacoustics database software OtoAccess™.
Data Storage with
Windows® Based Software
Speech Testing and
Communication
Transferring data to a PC is possible by two
different applications. OtoAccess™ is the
Interacoustics database platform that enables
data collection from multiple instrument sources
into one patient file. Hearing aid information
may also be included. NOAH hearing aid fitting
software will also integrate the test data when
used with the Interacoustics NOAH audiometry
module software.
• Live Voice speech testing is easy to perform
using the built-in goose neck microphone.
Sound Field Installation
Speech and pure tone may be presented under
free field conditions. Available system ranges
from 90dB SPL to 115dB SPL and is medically
approved. A set of connection panels, AFC8, is
available for connection to a sound booth.
• CD or tape players may be connected.
• Talk back is provided for sound field
installations.
• Talk forward is available using the built-in
microphone. The intensity is easily adjusted on
the front panel.
• Monitoring is possible either through the
operator’s headset or through the built-in
monitor loudspeaker.
Earphones and Noise
Excluders
• Amplivox features independent suspension of
the TDH39 earphones.
• Peltor - traditional noise excluding headset.
• Insert phones - EAR-Tone 5A insert phones
feature very low cross hearing and reduce need
for masking. Ambient noise is also attenuated.
