An audiometer is used extensively to measure what aspect of auditory function?

An audiometer is a specialized device designed primarily for the measurement of hearing sensitivity through various frequencies, particularly in the pure tone range. It generates pure tones at specific frequencies and allows the tester to present these sounds at different intensities to evaluate how well an individual can hear them. This is crucial in identifying the degree and type of hearing loss an individual may have.

Pure tone auditory testing using an audiometer helps determine the thresholds at which a person can detect sounds across a range of pitches, which is vital for diagnosing hearing impairments and planning appropriate interventions. The results can guide audiologists and hearing aid specialists in fitting hearing devices tailored to the individual's specific hearing needs.

Other options, such as measuring middle ear pressure or conducting otoscopy, involve different tools and methodologies focused on evaluating other aspects of auditory health. Similarly, assessing the electroacoustic function of hearing instruments pertains to the performance of the devices themselves rather than the individual’s hearing ability. Hence, the primary function of an audiometer revolves around evaluating pure tone hearing.
