Piecewise-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 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 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 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 کاملA Technical Comparison of Digital Frequency-Lowering Algorithms Available in Two Current Hearing Aids
BACKGROUND Recently two major manufacturers of hearing aids introduced two distinct frequency-lowering techniques that were designed to compensate in part for the perceptual effects of high-frequency hearing impairments. The Widex "Audibility Extender" is a linear frequency transposition scheme, whereas the Phonak "SoundRecover" scheme employs nonlinear frequency compression. Although these sch...
