Noise Management

AbstractMany hearing aid users are negatively impacted by wind noise when spending time outdoors. Turbulent airflow around hearing aid microphones caused by the obstruction of wind can result in noise that is not only perceived as annoying but may also mask desirable sounds in the listening environment, such as speech. To mitigate the adverse effects of wind noise, hearing aid developers have introduced several technological solutions to reduce the amount of wind noise at the hearing aid output. Some solutions are based on mechanical modifications; more recently, sophisticated signal processing algorithms have also been introduced. By offering solutions to the wind noise problem, these signal processing algorithms can promote more optimal use of hearing aids during outdoor activities. This article reviews how wind noise is generated in hearing aids, outlines the technological challenges in wind noise management, and summarizes the technological solutions that have been proposed and/or implemented in modern hearing aids.

Signal Processors

The development of very efficient digital signal processors has allowed the implementation of high performance signal processing algorithms to solve an important amount of practical problems in several engineering fields, such as telecommunications, in which very efficient algorithms have been developed to storage, transmission, and interference reductions; in the audio field, where signal processing algorithms have been developed to enhancement, restoration, copy right protection of audio materials; in the medical field, where signal processing algorithms have been efficiently used to develop hearing aids systems and speech restoration systems for alaryngeal speech signals. This chapter presents an overview of some successful audio and speech signal processing algorithms, providing to the reader an overview of this important technology, some of which will be analyzed with more detail in the accompanying chapters of this book.
