After this time they are permitted to sit a stringent theoretical and practical exam before a panel of industry experts to be declared competent to prescribe and fit hearing aids. This is a requirement for an Audiometrist to be a member of a professional body. Audiometrists must also comply with a continuing education program which ensures ...
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.
Audiometry (from Latin audīre 'to hear' and metria 'to measure') is a branch of audiology and the science of measuring hearing acuity for variations in sound intensity and pitch and for tonal purity, involving thresholds and differing frequencies. [1]
In addition, a test called a tympanogram is generally done. In this test, a small probe is placed in the ear and the air pressure in the ear canal is varied. This test tells the audiologist how well the eardrum and other structures in the middle ear are working. The ear canal volume indicates whether a perforation in the eardrum (tympanic ...
Other equipment must be designed and installed to work properly within this field. The most common cause of problems is earth loops , where different pieces of equipment are connected together by signal wires, but powered from different power sockets in different parts of the room or building.
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.

Other method for quantifying hearing loss is a hearing test using a mobile application or hearing aid application, which includes a hearing test. [1] [2] Hearing diagnosis using mobile application is similar to the audiometry procedure. As a result of hearing test, hearing thresholds at different frequencies are determined.
Audiological exam. Audiology (from Latin audīre, "to hear"; and from Greek branch of learning -λογία, -logia) is a branch of science that studies hearing, balance, and related disorders.
