Method for compensating a hearing impairment with multi-channel of digital a hearing aid and a hearing aid using the same

摘要

the use of hearing aids for hearing loss occurs differently nancheongja to the frequency characteristics of the channel and fine-tune it for each multi-channel digital hearing aids and hearing loss compensation method using the same are disclosed. The present invention includes the steps of converting the external audio signal into a digital signal; A digital signal based on the low frequency band, mid-range, split into a multi-channel step in which a high output in each channel; Separating each digital signs, high-band and low-band part of the signal inputted to each channel; Receiving the separated high-band and low-band part of this step and outputting the accumulated to calculate the hearing loss compensation gain for the band; And after using the hearing loss compensation gain, converts the data into an analog signal a hearing loss compensation, and including the step of outputting the audio signal converted to.
