An approach to calculating gain requirements for severely deaf children as a function of hearing loss which is independent of frequency response.
In an attempt to provide optimum listening conditions for hearing aid wearers a number of gain formulae have recently appeared in the literature. Required gains have invariably been measured at 1 kHz and expressed as a function of hearing loss. Recent research has shown that for children suffering from severe and profound deafness the 1 kHz required gain is highly dependent upon the low frequency response characteristic of the hearing aid. The present study proposes that the use of a 0.25 kHz gain formula would be advantageous with such children as it appears to be independent of the frequency response characteristic of the hearing aid.
