Hearing aids continue to be the main intervention for hearing loss but ease of use and control is of concern due to the small size of these aids. While technological advances in Bluetooth Low Energy have allowed for improved wireless control, in particular between personal electronic devices, its use for communication with hearing aids is problematic due to limited battery life. This paper outlines the implementation of acoustic wireless communication between personal electronic devices and hearing aids using On-Off Keying (OOK) and Frequency Shift Keying (FSK) between the frequencies of 16 and 20 kHz. Reliable communication with bit error rates less than 10 were achieved for OOK with maximum data signalling rates of 50, 35.7, and 27.8 bits per second (bps) obtained over 1, 2, and 3 metres respectively, while FSK provided maximum data signalling rates of 83.3, 50, and 27.8 bps over the same distances.
助听器仍然是听力损失的主要干预手段，但由于这些助听器体积小，其易用性和可操控性令人担忧。虽然低功耗蓝牙技术的进步实现了更好的无线控制，尤其是在个人电子设备之间，但由于电池续航有限，将其用于与助听器通信存在问题。本文概述了在16至20千赫兹频率之间使用开关键控（OOK）和频移键控（FSK）实现个人电子设备与助听器之间的声学无线通信。对于OOK，在1米、2米和3米距离上分别实现了最大数据信令速率为50、35.7和27.8比特每秒（bps），误码率低于10%的可靠通信，而FSK在相同距离上提供的最大数据信令速率分别为83.3、50和27.8 bps。
