an instrument used to measure the sensitivity of hearing
An instrument which is used to determine the acuity of hearing.
an instrument by which the power of hearing can be gauged and recorded on a scale
Origin: [L. audire to hear + -meter.]
An audiometer is a machine used for evaluating hearing loss. Audiometers are standard equipment at ENT clinics and in audiology centers. They usually consist of an embedded hardware unit connected to a pair of headphones and a test subject feedback button, sometimes controlled by a standard PC. Such systems can also be used with bone vibrators, to test conductive hearing mechanisms. Audiometer requirements and the test procedure are specified in IEC 60645, ISO 8253, and ANSI S3.6 standards. An alternative to hardware audiometers are software audiometers, which are available in many different configurations. Screening PC-based audiometers use a standard computer and can be run by anybody in their home to test their hearing, although their accuracy is not as high due to lack of a standard for calibration. Some of these audiometers are even available on a handheld Windows driven device. Clinical PC-based audiometers are generally more expensive than software audiometers, but are much more accurate and efficient. They are most commonly used in hospitals, audiology centers and research communities. These audiometers are also used to conduct Industrial Audiometric Testing. Because these audiometers can typically be calibrated to an accuracy of fractions of a decibel, calibration is more accurate than hardware audiometers. Some audiometers even provide a software developer's kit that provides researchers with the capability to create their own diagnostic tests.
Chambers 20th Century Dictionary
awd-i-om′et-ėr, n. an instrument for measuring and recording differences in the power of hearing.
The Standard Electrical Dictionary
An apparatus for obtaining a balance of induction from two coils acting upon a third. The third is placed between the other two and is free to move towards either. A scale is provided to show the extent of its movement. A varying or interrupted current being passed through the two outer coils, the preponderating current will produce the most induction if the central coil is equidistant. It can always be moved to such a point that there will be no inductive effect, one counteracting the other. Thus its position measures the relative induction. A telephone is in circuit with the intermediate coil and is used to determine when its position is such that no current is induced in it. It is sometimes used as a direct test of hearing. (See Hughes' Induction Balance.) Synonym--Acoutemeter.
