    Acoustic immittance audiometry - Immittance audiometry is an objective technique which evaluates middle ear function by three procedures: static immittance, tympanometry, and the measurement of acoustic reflex threshold sensitivity. Immittance audiometry is superior to pure tone audiometry in detecting middle ear pathology. Tympanometry

    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 ...

    The results of pure-tone audiometry are however a very good indicator of hearing impairment. Hearing disability is defined by the WHO as a reduction in the ability to hear sounds in both quiet and noisy environments (compared to people with normal hearing), which is caused by a hearing impairment.

    The absolute threshold of hearing (ATH), also known as the absolute hearing threshold or auditory threshold, is the minimum sound level of a pure tone that an average human ear with normal hearing can hear with no other sound present. The absolute threshold relates to the sound that can just be heard by the organism.
