Applications
The high quality of the AD226 makes it
particularly well suited for any stationary or
portable application where diagnostic testing
of air and bone conduction thresholds is
performed. The time saving automatic test
function combined with the computer
interface makes the AD226 ideal for
modern healthcare environments. The Talk
Forward function makes it easy to work with
the AD226, especially with sound cabin
installations. Full NOAH compatibility
completes the picture.
Automatic Testing
The AD226 incorporates a facility for
performing threshold determination
automatically. The test procedure is based on
either the Hughson-Westlake method ( up
5dB, down 10dB) or the standard OSHA
procedure. Desired test frequencies may be
selected freely by the user. The Bekesy test,
featuring pure tone, pulsed tone, narrow
band noise or white noise as stimulus as well
as masking with narrow band noise, is also
incorporated. Upon test completion the test
results can be recalled from memory of the
AD226 or transferred to a PC for database
storage or printing.
ABLB / SISI / Stenger / Langenbeck
As well as the pre-programmed ABLB and
SISI tests, the AD226 can perform the
Stenger test for evaluating malingering.
The Langenbeck Tone in Noise test is also
included.
Insert Phones
EarTone 5A Insert Phones ( optional) may
be supplied in addition to the standard
TDH39 audiometric headset. These insert
phones provide very low cross hearing and
effectively reduce the need for masking.
Ambient noise is also attenuated.
