What is Electronic Audiometer Design Guide about?
This document describes the design of an electronic circuit for an audiometer that can emit different auditory frequencies (120, 250, 500, 1000, 2000, 4000, 8000 Hz) through headphones at various decibel levels. The circuit uses an XR2206 integrated circuit to generate the audio sine wave signal coupled to the frequencies via a dipswitch and specific resistors. The LF353 operational amplifiers amplify the signal to vary the decibels. An Arduino and a display...
