Digital Audio Meter
An audiometer is a machine used for evaluating hearing loss. Audiometers are standard equipment at ENT (ear, nose, throat) clinics and in audiology centers. They usually consist of an embedded hardware unit connected to a pair of headphones and a test subject feedback button, sometimes controlled by a standard PC. Such systems can also be used with bone vibrators, to test conductive hearing mechanisms.
We had many models in audio meter.
