Title:
HEARING AID AND METHOD OF DETECTING VIBRATION
Document Type and Number:
WIPO Patent Application WO/2012/140818
Kind Code:
A1
Abstract:
The present invention provides a hearing aid capable of detecting contact vibration noise from a sound collecting signal. A hearing aid (100) is provided with two microphones (110-1, 110-2), a vibration component extracting unit (120) which extracts from sound collecting signals respectively obtained by the two microphones (110-1, 110-2) an uncorrelated component between these two sound collecting signals as a vibration component for each frequency band, a vibration noise identifying unit (130) which determines whether or not a contact noise occurs on the basis of the vibration component for each frequency band extracted by the vibration component extracting unit (120), an acoustic signal processing unit (140) which, when generating an acoustic signal by hearing aid processing of the above-mentioned two sound collecting signals, processes the acoustic signal depending on the presence or absence of the occurrence of the contact vibration noise, and a receiver (150) which converts the acoustic signal to sound.
