目的：本研究旨在评估使用无线远程麦克风技术通过信噪比 (SNR) 测量的噪声中语音识别能力的改善情况。这些麦克风通过射频直接向助听器传输数字信号，对于中国普通话听力障碍人群来说可能是一种有价值的辅助听力设备。方法：招募了 23 名患有双侧感音神经性听力损失的成人（19-80 岁）和 14 名儿童（8-17 岁）。普通话噪声听力测试用于测试成人受试者的语音识别能力，儿童普通话噪声听力测试用于儿童。受试者的感知信噪比是通过在 1.5、3 和 6 m 三种不同聆听距离下的句子识别能力来测量的。在每个距离处，在三种设备设置下获得信噪比：单独的助听器麦克风、单独的无线远程麦克风、以及同时助听器麦克风和无线远程麦克风。结果：在每个测试距离，对于成人和儿童组，使用无线远程麦克风的噪声中语音识别阈值均显着低于单独的助听器麦克风（P < 0.05），表明无线远程麦克风的 SNR 性能更好。此外，当使用无线远程麦克风时，测试距离对成人或儿童的噪声中语音识别没有影响。结论：无线远程麦克风技术可以显着提高中国普通话助听器用户在具有挑战性的听力环境中的语音识别性能。
Objective: This study was aimed at evaluating improvements in speech-in-noise recognition ability as measured by signal-to-noise ratio (SNR) with the use of wireless remote microphone technology. These microphones transmit digital signals via radio frequency directly to hearing aids and may be a valuable assistive listening device for the hearing-impaired population of Mandarin speakers in China. Methods: Twenty-three adults (aged 19–80 years old) and fourteen children (aged 8–17 years old) with bilateral sensorineural hearing loss were recruited. The Mandarin Hearing in Noise Test was used to test speech recognition ability in adult subjects, and the Mandarin Hearing in Noise Test for Children was used for children. The subjects’ perceived SNR was measured using sentence recognition ability at three different listening distances of 1.5, 3, and 6 m. At each distance, SNR was obtained under three device settings: hearing aid microphone alone, wireless remote microphone alone, and hearing aid microphone and wireless remote microphone simultaneously. Results: At each test distance, for both adult and pediatric groups, speech-in-noise recognition thresholds were significantly lower with the use of the wireless remote microphone in comparison with the hearing aid microphones alone (P < 0.05), indicating better SNR performance with the wireless remote microphone. Moreover, when the wireless remote microphone was used, test distance had no effect on speech-in-noise recognition for either adults or children. Conclusion: Wireless remote microphone technology can significantly improve speech recognition performance in challenging listening environments for Mandarin speaking hearing aid users in China.
