Optimized Active Noise Cancellation for Hearing Tests Using Auditory Masking Characteristics.

ABSTRACT:

Objective

Environmental noise poses a major barrier to the accuracy of self-administered hearing tests conducted outside clinical settings. There is a pressing need for effective noise control solutions to enable reliable hearing threshold measurements in everyday environments. This study introduces an optimized active noise cancellation (ANC) technique based on auditory masking characteristics.

Method

The method was implemented in a mobile hearing test system using calibrated true wireless Bluetooth earphones. Electroacoustic validation and clinical testing were conducted across four ANC scenarios: normal, generic ANC off, generic ANC on, and optimized ANC on in 65 dB(A) pink noise.

Results

A total of 50 participants completed hearing tests at eight frequencies (0.25
