What aspect of hearing does audiometry not measure?

Audiometry is a diagnostic process primarily used to evaluate hearing acuity and assess hearing thresholds. It involves various tests that determine how well a person can hear sounds at different frequencies and intensities. This process includes sound discrimination assessments, which measure a person's ability to differentiate between different sounds, such as distinguishing between similar-sounding words.

However, one important aspect that audiometry does not measure is the detection of earwax buildup. While earwax can affect hearing by blocking sound from reaching the eardrum, audiometry itself focuses on the auditory capability of the individual rather than physical obstructions in the ear canal. Therefore, any issues such as earwax buildup would need to be evaluated through other means, such as a physical examination or otoscopic inspection, rather than through the audiometric tests which classify hearing ability.

In summary, the correct option points out a limitation of audiometry in measuring factors that could influence hearing but are outside the scope of auditory testing itself.
