Bits, Bytes and Chips: Understanding Digital Hearing Aids, by Brian Csermak and Steve Armstrong

“Bits, Bytes and Chips” by Brian Csermak and Steve Armstrong looks at hearing aid digital signal processing (DSP) as the first DSP hearing aids were coming available in 1999. The authors explain sampling rates, MIPs, and detail how the A/D converter (analog-to-digital) can limit the performance of hearing aids. They also discuss the concepts of the noise floor, dynamic range, sampling resolution, over-sampling, and noise shaping.
