Comparison 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 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 کاملPiecewise-Linear Frequency Shifting Algorithm for Frequency Resolution Enhancement in Digital Hearing Aids
In human hearing, frequency resolution is a term used to determine how well the ear can separate and distinguish two sounds that are close in frequency. This capability of breaking speech sounds into various frequency components plays a key role in processing and understanding speech information. In this paper, a piecewise-linear frequency shifting algorithm for digital hearing aids is proposed...
متن کاملBenefit from, and acclimatization to, frequency compression hearing aids in experienced adult hearing-aid users.
OBJECTIVE The aim was to investigate whether frequency compression (FC) hearing aids provide additional benefit to that conferred by conventional amplification. DESIGN Participants wore the same hearing aid with FC enabled and disabled for six weeks (ABA design) in each condition. Speech recognition tests (in both quiet and in noise) were administered alongside two questionnaires. Performance...
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...
