HEARING AID APPARATUS PRESENTING VISUALLY TO DIRECTION OF SOUND SOURCE, AND METHOD OF OPERATING THE SAME

摘要

The present invention relates to a kind of hearing aids for the direction of sound source to be visually presented, and driving hearing aid apparatus and the direction for visually representing sound source are estimated by the sound pressure signal of the corresponding sound source in direction of a LED estimates that the direction of the received sound source of microphone uses delay and real time beam forming method. In addition, someone's wear hearing aid device, which can avoid separation, passes through manufacture hearing aid apparatus such as glasses from other people. Hearing-aid device includes multiple microphones, multiple luminescent devices, and control unit can control the direction of sound source, correspond to estimation direction visually to indicate that the luminescent device is opened in real-time direction, by estimating direction maximum beam power, by comparing the size of the light beam of acquisition, from all directions, by calculating light beam and above-mentioned beam output after respective direction divides full side AntWearer is based on according to the predetermined angular. ;The 2014 of copyright KIPO submissions;[Reference numerals] (AA) starts; (BB) do not have; (CC) " it is "; (S10) sound pressure signal is obtained; (S20) it calculates sound pressure level (SPL) and from above-mentioned surveyed sound pressure signal and threshold value (SPL_0) is set; (S40) movement of operating delay summation beamforming algorithm; (S50) beam output and beam power are calculated from each direction; The maximum beam power for estimating direction (S60) is the sound source in direction; (S70) direction that LED corresponds to estimation is lighted
