A Clinician’s Primer on How and Why to Perform the ‘ANSI Test’

Please note: exam questions are subject to change.

1. Why are ANSI tests conducted on hearing aids? To certify the color and design of the hearing aids. To ensure the hearing aid meets specific safety standards. To assess electroacoustic performance against a benchmark for quality control. To test the durability of the hearing aid.
2. What is the significance of tolerances in ANSI test measurements? They indicate the maximum volume level of the hearing aid. Tolerances define the range within which measurements are considered accurate. They determine the battery life of the hearing aid. Tolerances are irrelevant in modern hearing aids.
3. Which of the following is a major reason why ANSI tests may NOT represent real-world functioning of hearing aids? They are always conducted in soundproof rooms. Hearing aids are tested only at their maximum volume settings. ANSI tests use pure-tone signals, not representative of everyday sounds. The tests are conducted without the hearing aid being worn.
4. What does HFA-OSPL90 stand for in hearing aid testing? High-Frequency Average Output Sound Pressure Level at 90 dB Hearing Frequency Adjustment for Optimal Sound Pressure Level at 90 dB. High-Fidelity Audio Output Standard Pressure Level at 90 dB. Hearing Aid Frequency Output Sound Pressure Level at 90 dB.
5. Which of the following is NOT a strategy for finding the ANSI specifications for different manufacturer’s hearing aids? The internet. The programming software. The product packaging. ChatGPT.
