A Hearing test often comprises of a number of different examinations which, when taken together, can determine whether or not a person is suffering from hearing loss and to what extent. The Hearing care professional examine your ears with an Otoscope to make sure they are free of wax, if there are any problems in the ear canal or with the eardrum.
A Hearing health care professional conduct a hearing test which takes place in a sound-proof testing room, to check how well the ears are functioning and their ability to detect different levels of sound.
Some hearing tests prescribed for you:
Pure-tone audiometry is a behavioral test used to measure hearing sensitivity. This measure involves the peripheral and central auditory systems. In this test sound of different intensities and frequencies are played, usually through headphones in a sound-proof room. The result of the test is plotted on a graph called as an audiogram. This test is used to check the degree and type of hearing loss.
Tympanometry test, the condition of the middle ear and the mobility of the eardrum (Tympanic membrane). In this test, a small probe is placed in the ear canal and the air pressure in the ear canal is varied. It provides information about the middle ear functions, and the function of Eustachian tube.
Otoacoustic emissions are sounds given by the earpiece attached to a computer delivers sounds given off by the inner ear when the cochlea is stimulated by a sound. It plays quiet clicking noises and measures the response from your newborn child’s ears.
Auditory brainstem response (ABR) audiometry is a neurologic test of auditory brainstem function. Evoked potentials (EPs), or evoked responses, measure the electro physiologic responses. This test is generally done for pediatric. It requires the child to be sedated before the electrodes are placed. Its sensors are placed on child’s head and neck to check the response of their nerves to sound played through headphones.
Hearing care professional perform these tests to determine if the baby has a hearing loss, if so, what degree and type.
The goal of ASSR is to create an estimated audiogram from which questions regarding hearing, hearing loss and aural rehabilitation can be answered. It provides appropriate amplification by the age of 3 months of age.
