Audiometer
An audiometer is a device used to measure a person's hearing ability. In aviation, audiometers are used to test the hearing of pilots and other aviation personnel to ensure that they meet the minimum hearing requirements for their job. The audiometer produces sounds at different frequencies and volumes, and the person being tested indicates when they can hear the sound. The results are plotted on an audiogram, which shows the person's hearing ability at different frequencies. Audiometers are an important tool in aviation safety, as good hearing is essential for pilots to communicate effectively with air traffic control and to hear warning signals and alarms in the cockpit.
