Objective: Automated pure-tone audiometry (PTA) conducted outside a sound booth is heavily affected by environmental noise. This study aims to evaluate the performance of an automated PTA system, employing commercially available true wireless stereo earbuds with active noise cancellation (ANC) in noisy environments.
Design: The electroacoustic characteristics of earbuds are thoroughly evaluated. Hearing thresholds were measured by ANC earbuds and TDH-39 in three noise levels and two types of noise.
Study Sample: 21 normal-hearing participants for calibration and 22 participants below mild hearing loss for evaluation experiments.
Results: The average absolute differences between hearing thresholds measured via the standard manual audiometer in quiet and the automated PTA in various noise conditions, across octave frequencies ranging from 125 to 8000 Hz, were as follows: 5.2 (quiet environment without ANC), 5.4 (40 dBA pink noise with ANC), and 9.3 dB (55 dBA pink noise with ANC).
Conclusion: ANC can mitigate the impact of low-frequency noise (below 1000 Hz) on the accuracy of hearing level measurements, aligning with trends observed in objective experimental results. However, the influence of ANC on output levels warrants serious consideration in further practices.

Objective: This study was conducted to assess the ecological validity of the speech audiometry protocol recommended by Punch and Rakerd (2019) when implemented in older adults with hearing impairment. That protocol measures a listener's speech recognition threshold (SRT), most comfortable loudness level for speech (MCL), and uncomfortable loudness level for speech (UCL) in an integrated format that utilises single spondaic words as the stimulus set for all tests.
Design: Stimulus presentation and response collection were fully automated, test times were tracked electronically, and a short questionnaire was administered to assess subjective reactions to the test procedures.

To date, pure-tone audiometry remains the gold standard for clinical auditory testing. However, pure-tone audiometry is time-consuming and only provides a discrete estimate of hearing acuity. Here, we aim to address these two main drawbacks by developing a machine learning (ML)-based approach for fully automated bone-conduction (BC) audiometry tests with forehead vibrator placement.
