Which term means pertaining to hearing?

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

Answer: (D)

The idea being tested is how to express “related to hearing” in medical terminology. Auditory fits because it comes from the root aud- meaning to hear, with the suffix -ary (or -ory) that forms an adjective meaning pertaining to. You can use it in phrases like auditory function or auditory system to describe anything connected to hearing. The other terms refer to a tool, a chart, or a procedure rather than an adjective describing hearing: an audiometer is a device that measures hearing, an audiogram is a chart of hearing thresholds, and audiometry is the testing process itself. So the term meaning pertaining to hearing is auditory.
