Designing an energy efficient Digital Signal Processing hearing aid system

This paper focuses on design issues related to the development of an energy efficient Digital Signal Processing (DSP) hearing aid system that can result in various DSP hearing aid products. The approach is predicated on utilizing commercially available DSP chips while meeting system requirements and end-user expectations. It describes how energy efficiency can be achieved at various levels, designing and tailoring the necessary algorithms to consume less power, selecting appropriate components with a focus on functionality - satisfying end-user expectations. The approach has led to the development of binaural DSP hearing aids in various form factors.
