Fast active noise control for robust speech acquisition
Luis Vicente, Stephen J. Elliott, Enrique Masgrau · 1999
Many listeners with medium-severe hearing loss present audiograms with high frequency loss descending profiles. These patients can resolve spectral cues normally for lower frequency signals but they often show less ability to use high frequency information. We have presented in this paper a new Discrete Exponential Transform (DET), its fundamentals, and the correspondingly algorithm designed to compensate this particular feature of the impairment. The preliminary results of the processed speech material in two impaired listeners suggests that DET could be implemented in digital hearing aids to be used in patients with severe and moderate-severe hearing loses.
