Abstract

In this chapter, signal-processing methods for digital hearing aids are discussed and the author also describes how auditory characteristics and speech understanding abilities change because of hearing impairment as well as aging. In particular, the author introduces various approaches to signal processing such as noise-reduction methods, consonant-enhancement methods, and speech rate or intonation-conversion methods. Past and recent artificial middle ears are also discussed as one form of hearing aid.
