Signal monitor for audiometry.
Conventional volume unit (VU) and auditory monitors of signals generated by or fed through an audiometer do not allow monitoring of the signal after the attenuator or output selector. An amplifier-compressor circuit has been designed and constructed which allows auditory monitoring of the electrical signal at the transducer. The circuit and its use are described.
