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 (0.25–8 kHz), and results were compared to standard audiometry. The optimized ANC yielded the highest signal-to-noise ratio in noisy conditions and demonstrated strong agreement with standard hearing thresholds (r = 0.99, p \u003C.01) in normal environments. Under 65 dB(A) noise, the proposed method significantly outperformed generic ANC with smaller hearing measurement error, improving threshold accuracy across most frequencies. Conclusion: The proposed ANC technique enhanceshearing test reliability in noisy conditions, supporting accurate, self-administered hearing assessments outside clinical settings. This technology has strong potential for home or community-based hearing healthcare applications.  \nINDEX TERMS Active noise cancellation, hearing test, noise control, noisy environment.  \nClinical Impact—This study presents an optimized active noise cancellation (ANC) technique based on auditory masking principles to improve the accuracy of self-administered hearing tests in noisy environments. By integrating the algorithm into a mobile application and true wireless Bluetooth headsets, the system enables reliable pure-tone threshold measurements without the need for a soundproof room or clinical supervision. The proposed approach has demonstrated a smaller hearing level difference and strong correlation with standard audiometry and has produced high-accuracy predictions in both quiet and noisy settings, supporting its feasibility for deployment in home or community-based hearing screening.
