Application of digital signal processing to hearing aids: a critical survey.
نویسندگان
چکیده
An audiologic rationale for the application of digital signal processing techniques to hearing aids is developed. These techniques enable complex processing beyond that possible in presently available analog aids. A critical survey of algorithms for filtering, nonlinear processing, noise reduction, speech enhancement, and feedback reduction is presented. The paper concludes with a discussion of practical considerations for implementation.

متن کاملImproving speech intelligibility in hearing aids. Part I: Signal processing algorithms
The improvement of speech intelligibility in hearing aids is a traditional problem that still remains open and unsolved. Modern devices may include signal processing algorithms to improve intelligibility: automatic gain control, automatic environmental classification or speech enhancement. However, the design of such algorithms is strongly restricted by some engineering constraints caused by th...
