audiometer
Measures auditory acuity
An audiometer is a device used to measure hearing ability.
It produces tones at various frequencies and volumes, allowing clinicians to determine the range and sensitivity of a patient's hearing.
Audiometers are standard equipment in hearing tests and audiology clinics: The audiometer revealed significant hearing loss in his left ear.
