METHOD FOR REMOTE INTERACTION OF HEARING AID AND MOBILE DEVICE USING BLUETOOTH COMMUNICATION Russian patent published in 2023 - IPC H04R25/00 

FIELD: acoustics; hearing aids.

SUBSTANCE: method for remote interaction between a hearing aid and a mobile device using Bluetooth communication, which consists in pairing a smartphone with a Bluetooth 4.0 interface and higher, supporting Bluetooth low energy technology, with a hearing aid supporting the BLE protocol, while the hearing aid contains a microphone, an amplifier, a telephone, a BLE transceiver with the necessary connections that implements wireless communication using the BLE protocol, a built-in transceiver antenna A with matching circuits operating in the radio frequency range used in the Bluetooth protocol. The hearing aid contains an attenuator At, which reduces the power of the signal supplied to the antenna. The initial setup of each hearing aid is performed, the user ID, indicator on the right or left ear, number of programs, gain, step and gain control limits in the hearing aid are recorded. The radio channel digitally transmits the values of the identifier, the indicator of use on the right or left ear and the current values of the program number and the set gain, when the program number or gain is changed by the controls located on the hearing aid case, the current values of the paired hearing aids or the only hearing aid are also transferred to a smartphone.

EFFECT: ability to remotely adjust the volume and switch hearing aid programs using a smartphone.
