Standardized Electroacoustic Evaluation of Hearing Aid Performance

Please note: exam questions are subject to change.

1. What is the testing difference between ANSI S3.22-2009/2013 and IEC 60118-7? Test signal Test conditions Hearing aid settings There is no difference
2. There are TWO (2) volume control settings that are used when conducting ANSI/IEC tests. What are they? Full-on gain and use settings Use settings and reference test gain Full-on gain and reference test gain None of the above
3. What is the acceptable results tolerance range for Average OSPL90? +/- 1dB +/- 4dB +/- 6dB +3dB
4. What is the difference between ANSI S3.22-2009/2014 and ANSI S3.22-2003? There is no difference between these two standards The 2003 standard is newer The 2003 standard includes attack and release measures The 2003 standard includes input-output measures
5. Why does the Verifit 2 NOT include the directional mic test as an option when doing ANSI 2cc coupler measures? The ANSI standard requires the hearing aid being tested to be programmed linear. The VF2 directional test does not require this setting Because the testing is an additional expense to the patient Because adding the directional test would take too long None of these answers are correct
