Which term is an instrument to measure hearing?

• A. Audiogram
• B. Audiometry
• C. Audiometer
• D. Auditory

Answer: (C)

Measuring hearing relies on an instrument that delivers controlled sounds at different frequencies and intensities and records whether the person can hear them. The device designed for this purpose is an audiometer. It feeds tones through headphones or ear inserts in a sound-treated environment and notes the softest level at which the listener detects each tone, building a profile of hearing sensitivity. The results are commonly shown on an audiogram, which is the graph of thresholds across frequencies, while audiometry refers to the overall testing process. The term auditory describes anything related to hearing, but it is not the instrument itself.
