Which diagnostic test assesses auditory function by presenting sound stimuli to the ear?

• A. Angiography
• B. Auscultation
• C. Albumin test
• D. Audiometry

Answer: (D)

Assessing auditory function by delivering controlled sound stimuli to the ear is audiometry. In this test, tones or speech are presented through headphones or ear inserts, and the person indicates when they hear the sound. The responses are used to determine hearing thresholds across frequencies, typically shown on an audiogram, which helps identify the degree and type of hearing loss.

The other options aren’t about measuring hearing with sounds: angiography visualizes blood vessels using contrast; auscultation relies on listening to body sounds with a stethoscope; and the albumin test checks for protein in urine.
