Abstract

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.

自动纯音测听使用真正的无线立体声耳塞与主动噪声控制。

目的：在音箱外进行的自动纯音测听（PTA）受环境噪声的影响较大。本研究旨在评估自动化PTA系统的性能，采用市售的具有主动降噪（ANC）的真无线立体声耳塞在嘈杂环境中。设计：全面评估耳塞的电声特性。使用ANC耳塞和TDH-39在三种噪声水平和两种噪声类型下测量听力阈值。研究样本：21名听力正常的受试者进行校准，22名轻度听力损失以下的受试者进行评估实验。结果：在125 ~ 8000hz的不同噪声条件下，通过标准手动听力计测量的安静环境和自动PTA的听力阈值的平均绝对差值分别为：5.2（安静环境无ANC）， 5.4 （40 dBA粉红噪声有ANC）和9.3 dB （55 dBA粉红噪声有ANC）。结论：ANC可以减轻低频噪声（低于1000 Hz）对听力水平测量精度的影响，与客观实验结果观察到的趋势一致。然而，在进一步的实践中，非国大对产出水平的影响值得认真考虑。
