Diagnostic Audiometer
MADSEN Itera II combines top performance in a stylish cabinet and
offers a range of options so that you can configure the best solution for
your clinic or dispensing practice.
Discover the benefits of Hearing Instrument Simulation
With the automatic Hearing Instrument Simulator you will be able
to show your patients the benefits of wearing hearing instruments.
Benefits which can sometimes be very difficult to explain – especially
to someone who has never worn a hearing instrument before. This is
all done in a quick, easy and efficient way, as the Hearing Instrument
Simulator is automatically setup based on the stored audiogram.
Opening up a new world of possibilities
With its compact footprint, angled front panel and easily accessible
connection panel, Itera II is ideal for use in a sound booth setting
and with its integrated microphones, NOAH3 interface and automatic
Hearing Instrument Simulator it is also the perfect choice for the
dispensing practice. Finally weighing in at just ten compact pounds or
under 5 kg, the Itera II diagnostic audiometer is also well-suited for
portable use.

Wide range of special
tests
Easy switching between
left and right
Every function is at your
fingertips
Smart rotary knobs
Easy integration with other
processes for seamless workflow
The MADSEN Itera II is part of the
OTOsuite universe which means
the audiometric workflow easily
integrates with the immittance and
fitting testing processes. This allows
you to perform audiometry, fitting,
counseling and verification in a
seamless workflow. One-click data
logging, combined immittance and
audiometry reporting contribute to
a more efficient testing process and
help eliminate paperwork.
