Audiometry is the term used to describe formal measurement of hearing. The measurement is usually performed using an "audiometer" by an "audiometery". Audiometry is a subjective test--it is not an objective measurement. It depends on people pushing a button or raising their hand, when they hear a tone. Co-operation is needed.
