Can you fail a hearing test?

Hearing screenings are frequently part of a medical exam or are even offered at health fairs and online websites. Screenings are not true hearing tests; they are a pass-fail challenge to determine if there is a possibility of hearing loss. If you fail a hearing screening, there's a good chance you have hearing loss.

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.

What is behavioral hearing test?

During behavioral hearing tests, the child (and typically the parent) is seated in a sound booth. Sounds of varying intensity are presented to the child via calibrated speakers or earphones. The sounds may consist of speech or music as well as specific frequencies that are critical to access (hear) the different sounds of speech. The audiologist looks for and records the child's responses to the softest sounds presented and plots them out on a graph called an audiogram.

Why is my child so quiet during the ear test?

The response is very faint so the child must be extremely quiet during the test. Because the response is so faint, it may be obscured by the presence of ear wax, middle ear pathology (for example, fluid, pressure) or the presence of pressure equalization (PE) tubes.

Some are used with adults when physicians desire to know the status of the hearing nerve.

What is ABR hearing aid?

With Auditory Brainstem Response (ABR), the patient sleeps or rests quietly while ​sounds are played to the ear through a small earphone. Recording electrodes on the head send the brain wave response to a computer where it is analyzed by the clinician. Many children require light sedation. When hearing loss exists, the results from this test can be used to select and set hearing aid characteristics for children. The ABR is also used with adults, in order to screen for certain types of tumors that can occur within the auditory system.

What is tympanometry used for?

Tympanometry is used to diagnose problems with the eardrum and middle ear space. Problems such as fluid in the middle ear, a tear or hole in the eardrum, or problems with the small bones in the middle ear can result in hearing loss that generally can be treated medically or surgically. To obtain a tympanogram, a small earphone is placed in the ear canal and eardrum movement is measured in response to air pressure changes.
