Abstract
Hearing aids continue to be the main intervention for hearing loss but their ease of use and control is of concern due to their small size. 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 their limited battery life. This research investigates the implementation of acoustic wireless communication between personal electronic devices and hearing aids using multiple modulation schemes utilizing frequencies between 16 and 20 kHz. The performance of each modulation scheme is assessed over a 3 metre range and the power consumption compared to that of Bluetooth Low Energy.
