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.

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.
Real ear measurement is the measurement of sound pressure level in a patient's ear canal developed when a hearing aid is worn. It is measured with the use of a silicone probe tube inserted in the canal connected to a microphone outside the ear and is done to verify that the hearing aid is providing suitable amplification for a patient's hearing loss.

When audiometry is applied to industry, audiometrists are sometimes also called Occupational Hearing Conservationists. [ 18 ] [ 19 ] [ 20 ] When Audiometrists become qualified as Audiologists, they are more commonly referred to as Hearing Instrument Specialists, and are licensed hearing professionals that perform diagnostic hearing evaluations ...
The tone decay test (also known as the threshold tone decay test or TTDT) is used in audiology to detect and measure auditory fatigue. It was developed by Raymond Carhart in 1957. In people with normal hearing, a tone whose intensity is only slightly above their absolute threshold of hearing can be heard continuously for 60 seconds.
