audiometers
Sound measurement devices
Audiometers are instruments that measure hearing ability.
They produce tones at various frequencies and volumes to test how well a person can detect sounds across the audible range.
Audiologists use them to diagnose hearing loss and determine whether someone needs hearing aids: The audiometer revealed significant high-frequency hearing loss in her left ear.
