The standard and most common type of hearing test is pure tone audiometry, which measures the air and bone conduction thresholds for each ear in a set of 8 standard frequencies from 250Hz to 8000Hz. The test is conducted in a sound booth using either a pair of foam inserts or supraural headphones connected to an external audiometer.
An audiometer is a machine used for evaluating hearing acuity. 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.
Pure-tone audiometry is the main hearing test used to identify hearing threshold levels of an individual, enabling determination of the degree, type and configuration of a hearing loss [1] [2] and thus providing a basis for diagnosis and management.
Schwabach test, a variant of the Rinne test; Pure tone audiometry is a standardized hearing test in which air conduction hearing thresholds in decibels (db) for a set of fixed frequencies between 250 Hz and 8,000 Hz are plotted on an audiogram for each ear independently. A separate set of measurements is made for bone conduction.
An audiologist conducting an audiometric hearing test in a sound-proof testing booth Identification of a hearing loss is usually conducted by a general practitioner medical doctor , otolaryngologist , certified and licensed audiologist , school or industrial audiometrist , or other audiometric technician.
is a medical device (exposed to the relevant procedures of testing and certification); is adjusted using audiometry procedures. [38] is designed for use by doctor's prescription; Functionality of hearing aid applications may involve a hearing test (in situ audiometry) too. However, the results of the test are used only to adjust the device for ...

It is an acoustic measure, measured by a microphone, as part of the ear canal probe, inserted into the ear canal. The test should not be used to assess the sensitivity of hearing and the results of this test should always be viewed in conjunction with pure tone audiometry. Tympanometry is a valuable component of the audiometric evaluation.
