Frequency Shaping in Hearing Aids
Contrast-enhancing frequency shaping (CEFS) produces a better representation of formants in the auditory nerve (AN) response of an impaired ear than conventional amplification schemes (Miller et al., 1999; Sachs et al., 2002). CEFS compensates for the broadened tuning curves and elevated thresholds of an impaired ear by adjusting the relative amplitudes of the formants without distorting the sp...
متن کاملGain, frequency response, and maximum output requirements for hearing aids.
This article applies the gain and frequency response and maximum output selection procedures currently recommended by the National Acoustic Laboratories (NAL) of Australia to the audiograms of a representative group of adult and child clients of Australian Hearing Services (AHS) to specify the performance that is required of various types of hearing aids in order to ensure that they can provide...
متن کاملComparison of two frequency lowering algorithms for digital hearing aids
A considerable percentage of listeners with severe hearing loss have audiograms where the losses are high for high frequencies and low for low frequencies. For these patients, lowering the speech spectrum to the frequencies where there is some residual hearing could be a good solution to be implemented for digital hearing aids. In this paper we have presented two different frequency–lowering al...
متن کاملComparison of performance with frequency transposition hearing aids and conventional hearing aids.
Four experienced hearing aid users were evaluated using a frequency transposition (TranSonic) hearing system. Following a trial period, the Abbreviated Profile of Hearing Aid Performance (APHAB) and a variety of speech audiometric measures were used to compare the frequency transposition fitting with each subject's conventional hearing aids. A single-subject study design with a series of repeat...
متن کاملHearing Aids for Musicians
When comparing music to speech, there are four essential physical differences that warrant consideration during a hearing aid (or cochlear implant) fitting. Understanding these differences and selecting appropriate hearing aid circuitry will help to optimize the enjoyment of music for the hard-of-hearing listener. This applies equally to those who are musicians as to those who like to listen to...
