Integrated circuit technology in hearing aids

In recent years, digital technology has enabled the provision of many new hearing aid features such as noise reduction, feedback suppression and environment classification. As silicon technology evolves, more and more features will be possible within the existing package size and power budget. This paper provides an overview of integrated circuit technology and its application to hearing aid design. The architecture of a digital hearing aid circuit is described in light of the system constraints. The talk will conclude with a brief discussion of expected technological advances and their impact on hearing aid design.
