Pure tone audiometry is a diagnostic test used to measure an individual's hearing abilities, specifically their ability to detect and perceive pure tones across a range of frequencies. It is one of the most commonly used methods to assess hearing loss and determine the degree and type of impairment.
During a pure tone audiometry test, the individual is seated in a soundproof room and wears headphones. The test consists of a series of tones played at different frequencies and intensities, also known as decibels. The individual indicates when they can hear the tones by raising their hand or pushing a button.
The results of the test are plotted on an audiogram, which is a visual representation of the individual's hearing thresholds. The audiogram displays the softest sounds the person can hear at each frequency. Based on the audiogram, the severity and configuration of the hearing loss can be determined.
Pure tone audiometry is helpful in diagnosing a variety of hearing disorders, including conductive, sensorineural, and mixed hearing loss. It can also be used to monitor changes in hearing over time. The test is safe, non-invasive, and widely available in audiology clinics and hospitals.
Overall, pure tone audiometry is an essential tool in the evaluation and management of hearing loss, as it provides valuable information about an individual's hearing abilities and helps guide appropriate treatment and rehabilitation options.
