What frequency range does extended high frequency audiometry cover?

• A. 9000-16,000 Hz
• B. 4000-8000 Hz
• C. 15,000-25,000 Hz
• D. 900-1600 Hz

Answer: (A)

Extended high frequency audiometry is a specific type of hearing test that measures hearing sensitivity at frequencies higher than those typically assessed in standard audiometry. The frequency range it covers is generally from 9000 Hz up to 20,000 Hz or even higher, with 9000-16,000 Hz being a commonly accepted segment for this testing. This specialized testing is particularly important for detecting high-frequency hearing loss, which can occur due to factors like noise exposure or ototoxic medications. It can provide valuable information about a person's auditory health and help in the early identification of hearing changes that may not be captured in conventional audiometry, which usually focuses on frequencies from 250 Hz to 8000 Hz. Options that fall outside this range, such as those focusing on lower frequencies or narrower bands, do not encompass the purpose or design of extended high frequency audiometry, which is specifically geared towards higher frequency sound perception.
