WIRELESS COMMUNICATION METHOD AND SYSTEM OF HEARING AID APPARATUS

摘要

A wireless communication method of a hearing aid apparatus comprises the steps of extracting an audio signal received via a first hearing aid; determining a beam forming vector for forming a beam toward the back of a user wearing the first hearing aid and a second hearing aid; performing pre-coding of the audio signal by using the beam forming vector; and transmitting the pre-coded audio signal via a first multi-antenna to the second hearing aid, wherein the first multi-antenna is disposed on the first hearing aid and a second multi-antenna is disposed on the second hearing aid.
