High Frequency Audiometry - Interacoustics Affinity 2.0 Additional Information

1.7.1

High frequency audiometry

High f requency audiometry (above 8 kHz) is perf ormed using the same procedure as normal air conduction
audiometry. Note, however, that you are only allowed to test within the range of the headset calibration That
is, if the headset is only calibrated f or a range of 125 Hz – 8 kHz you will not be allowed to present tones at
higher f requencies.
High f requency audiometry is helpf ul when testing hearing impairments caused by ototoxicity, noise
exposure and acoustic traumas as these mainly af f ect the high f requencies. This f requency area is more
susceptible to the ef f ects of external f actors such as medications and loud noises than the low and middle
f requencies.
Required items:
• The Af f inity 2.0 hardware
Licensed AC440 Audiometry module within your Af f inity
•
A calibrated high f requency audiometric headset (Koss R/80, DD450, HDA300 or HDA200)
•
A response button
•
Test procedure:
1) Open the AC440 module through your patient management system, Noah or OtoAccess®.
2) If needed select a test protocol in the Protocols and sessions
3) To perf orm a high f requency audiometry, press the HF button
screen.
4) Conduct high f requency audiometry using the normal air conduction audiometry method (see section
1.6 above f or details), ensuring that you are using proper headsets. The f ollowing headsets are
available:
Koss R/80 can be calibrated f or 8 kHz to 20 kHz

HDA 200 can be calibrated f or 125 Hz to 20 kHz

DD450 can be calibrated f or 125 Hz to 20 kHz

HDA300 can be calibrated f or 125 Hz to 20 kHz
