MODEL RELEASED. Hearing test. 15-year-old girl who is having her hearing tested. The headphones are used to transmit beeps of sound at different frequencies and volumes. The girl is indicating whether she hears each beep by pressing a button on a handheld device (lower left). An audiologist (not seen) is lowering the volume of sound for each frequency until it is no longer audible. This gives the patient's hearing threshold at each frequency,which can be plotted on an audiogram. Treatment depends on the extent,type and cause of the hearing loss.
