Abstract:Because the puretone audiometer is an important medical instrument used to diagnose hearing loss, the IEC and ANSI has been published a specification with which audiometer should comply. This paper describes development of Linux based real-time spectrum analyzer which is dedicated to puretone audiometer. It can measure not only hearing level but also compliance of IEC standard for puretone audiometer such as frequency accuracy, harmonic distortion, pulsed tone, narrow band noise and linearity. We have verified… Show more
