Hearing aid. Measurement of electroacoustical characteristics

Abstract

In this work we show the results obtained from several measurements, on hearing aid (HA) prototype carried out at the Acoustic Laboratory of the Centro de Ciencias Aplicadas y Desarrollo Tecnológico (CCADET) at the Universidad Nacional Autónoma de México (UNAM). The hearing aid has been developed at the Electronics Laboratory of the same Center. All the electroacoustic measurements have been made according to the recommendations established in the ANSI and IEC Standards for hearing aids.
