The data received from an audiometer is called an audiogram. An audiometer is a machine used for evaluating hearing acuity. An experimenter would generally use an audiometer to find the auditory threshold of a subject. Hearing can be measured by behavioral tests using an audiometer. An audiometer is used to determine a person's hearing sensitivity at different frequencies. Hearing level is the sound pressure level produced by an audiometer at a specific frequency. The most common type of audiometer generates pure tones, or transmits parts of speech. An audiometrist conducts hearing tests, or "audiometric screening", with an Audiometer to establish hearing levels. Alternatively, this test can be performed more accurately using two-channel audiometer using pure tone signals. The Audiometer puts them over the top and they win.
