MODEL RELEASED. Hearing test. Young girl in a soundproof cabin undergoing a hearing test. An audiologist is using an audiometer (lower centre) to produce sound at different frequencies. She is testing the ability of the girl to hear over a range of frequencies. The girl indicates every time she hears a sound. The audiologist lowers the volume of sound until it is no longer audible to her, a measure of her hearing threshold at each frequency. This type of hearing test, known as pure-time audiometry, is used to assess the extent of a patient's hearing loss and to investigate possible causes. Photographed in Rovereto, Italy.
