Which instrument would you use to quantify hearing thresholds during a formal assessment?

• A. Audiometer
• B. Otoscope
• C. Weber and Rinne tests
• D. Acoustic reflectometer

Answer: (A)

To quantify hearing thresholds, you need an instrument that can deliver sounds at precise frequencies and controlled intensities and record the softest level a person can hear. An audiometer does exactly that, enabling pure-tone thresholds across standard frequencies and producing an audiogram that shows hearing sensitivity in decibels across ears. It’s the core tool for formal hearing assessments in clinical settings, often used in a sound-treated booth with patient responses to determine thresholds for air and bone conduction. Other tools serve different purposes: an otoscope is for visually inspecting the ear canal and eardrum, not measuring hearing sensitivity; Weber and Rinne tests use tuning forks to screen or help differentiate types of loss but don’t quantify thresholds; and an acoustic reflectometer (tympanometer) assesses middle-ear function rather than hearing thresholds.
