Comparison 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 کاملFrequency shaping and multiband compression in hearing aids.
Compression and noncompression amplification were compared for a range of conditions. The noncompression conditions included flat-frequency response and "LDL frequency response," with and without peak clipping. The compression conditions included a single-band compression system and two combinations of a two-channel compression system. The LDL frequency response was obtained by finding the LDL ...
متن کاملFrequency compression/transposition of fricative consonants for the hearing impaired with high-frequency dead regions
In this paper we present the first evaluation results of a carefully designed piecewise linear frequency compression curve, to improve the recognition of fricative consonants, for patients with high-frequency dead regions in the cochlea. Our original frequency compression/transposition algorithm takes into account the average short-time spectrum of the most frequent Brazilian Portuguese fricati...
متن کاملFrequency 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 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...
