ASA S3.42 Part 1 – American National Standard for Testing Hearing Aids with a Broad-Band Noise Signal

This standard describes techniques for characterizing the steady-state performance of hearing aids with a broad-band noise signal. The need for such a standard arises from the importance of assessing the performance of hearing aids in environments more nearly representing their real-world use. The noise test signal specified herein has been employed by the National Bureau of Standards for over 20 years in testing hearing aids. Among the tests described are noise saturation sound pressure level, noise gain, frequency response, family of frequency response curves and output versus input characteristic. Additionally, the appendix recommends use of the coherence function to indicate the validity of frequency response measures and distinguishes between use of random and pseudo-random noise and asynchronous versus synchronous analysis.
