Regular Tests for Hearing Loss Caused by Age
Friday, November 4th, 2011
Hearing loss due to aging is affecting about a 3rd of older US people aged 65 to 85, according to the Nation's Institutes of Health. Influenced seniors have difficulties in understanding and replying to conversation.
Hearing loss has effects on the elderly disproportionately, and also is affecting the young, even newly born babies. A sequence of tests, including audiometry, general screening, Tune Fork, BAER and Otoacoustic Emissions can help identify the cause and treatment.
The general screening test is the first test performed either as routine care or connected with hearing Problems, and it is done on each ear separately. Te provider will speak words at different levels to check the way the patient reacts to sound level. The patient will often get asked to repeat the words. If he is having Problems hearing the words, the provider will speak loudly to see if the reply changes.
Tuning Fork Tests involve two-pronged instruments, which make a tone while vibrating. The provide will usually strike the instrument, leading it to vibrate and create a sound. The vibrations created are used to figure out the patient’s capability to hear different sound frequencies in the vibrating area of the middle ear and the eardrum.
The Tuning Fork Test is also used to test for damage sensors, damage of the nerves in the internal ear, or damage in both areas. Primarily based on the patient’s capability to hear the sound, the medical care supplier will be well placed to determine whether the hearing loss is due only to the nerves or if the problem is the sound reaching the nerves.
The Pure Tone Audiometry process is performed using an audiometer machine, which measures hearing tones through a headphone in order to determine hearing loss. The testing is done by an audiologist who controls the tone and volume of the sounds in the earphones. The patient presses a button or lifts his hand when he hears the sound and the supplier keeps fixing the sound to test when the patient isn't able to listen to it. The audiologist will then increase the volume and repeat the test.
Auditory Brain Stem Reply (ABR) or (BAER) brain stem auditory evoke response is a test aiming to identify sensorineural hearing loss by placing electrodes on the scalp and on each earlobe. Clicking noises are then broadcast through the ear[hones and the electrodes measure the brain reaction to the clicking sound. The reply is recorded on a graph.
Finally, Otoacoustic Emissions Testing (OAE) is a screening test tool used to check the hearing of newborns. Testing involves placing a little mic in the ear canal, which uncovers any reply to sounds in the interior ear.
