Noise reduction in hearing aids: a review.
Background noise is particularly damaging to speech intelligibility for people with hearing loss. The problem of reducing noise in hearing aids is one of great importance--and great difficulty. The problem has been addressed in many different ways over the years. The techniques used range from relatively simple forms of filtering to advanced signal processing methods. This paper provides a brie...
متن کاملNoise reduction for "intelligent" hearing aids
One major problem of people with hearing impairment is the 'Coctail-Party-Effect', i.e., the reduced ability to understand speech in noisy environments. Normal hearing listeners use binaural information, i.e., interaural level and phase/time differences in addition to monaural cues to localize sound sources in the environment. Based on the localization result and on the monaural cues, the liste...
متن کاملHollowness perception with noise-reduction hearing aids.
The efficacy of "noise-reduction" hearing aids in reducing the hollowness perception of one's own voice during vocalization was examined. Binaural Siemens 283 ASP hearing aids were worn by 2 groups of listeners, one with primarily high-frequency loss (Group A) and one with loss in both high- and low-frequencies (Group B). Electroacoustic parameters on the hearing aids were adjusted initially fo...
متن کاملCombined Active Noise Control and Noise Reduction in Hearing Aids
This paper presents a combined active noise control and noise reduction scheme for hearing aids to tackle secondary path effects and effects of signal leakage through the fitting. While such leakage contributions and the secondary accoustic path from the reciever to the tympanic membrane are usually not taken into account in standard noise reduction systems, they appear to have a non-negligible...
متن کاملDigital hearing aids: a tutorial review.
The basic concepts underlying digital signal processing are reviewed briefly, followed by a short historical account of the development of digital hearing aids. Key problem areas and opportunities are identified, and the various approaches used in attempting to develop a practical digital hearing aid are discussed.
