The hearing impaired typically experience more frustration, anxiety, irritability, depression, and disorientation than those with normal hearing levels. The standard rehabilitation tool for hearing impairment is an electronic hearing aid whose main components are transducers (microphone and receiver) and a digital signal processor. These electronic components are manufactured by supply chain rather than by hearing aid manufacturers. Manufacturers can use custom-designed components or generic off-the-shelf components. These electronic components are available as application-specific or off-the-shelf products, with the former designed for a specific manufacturer and the latter for a generic approach. The choice of custom or generic components will affect the product specifications, pricing, manufacturing, life cycle, and marketing strategies of the product. The World Health Organization is interested in making available to developing countries hearing aids that are inexpensive to purchase and maintain. The hearing aid presented in this article was developed with these specifications in mind together with additional contemporary features such as four channels with wide dynamic range compression, an adjustable compression rate for each channel, four comfort programs, an adaptive feedback manager, and full volume control. This digital hearing aid is fitted using a personal computer with minimal hardware requirements in intuitive three-step fitting software. A trimmer-adjusted version can be developed where human and material resources are scarce.<\/jats:p>","DOI":"10.1177\/1084713810380934","type":"journal-article","created":{"date-parts":[[2010,8,19]],"date-time":"2010-08-19T06:25:54Z","timestamp":1282199154000},"page":"64-72","source":"Crossref","is-referenced-by-count":14,"title":["Designing of a Digital Behind-the-Ear Hearing Aid to Meet the World Health Organization Requirements"],"prefix":"10.1177","volume":"14","author":[{"given":"Ricardo","family":"Ferreira Bento","sequence":"first","affiliation":[{"name":"University of Sao Paulo, Sao Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvio","family":"Pires Penteado","sequence":"additional","affiliation":[{"name":"University of Sao Paulo, Sao Paulo, Brazil,"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2010,8,19]]},"reference":[{"key":"atypb1","volume-title":"Tratado de otologia, Trans.
