In the United States alone, there are about 32.5 million people that suffered hearing loss. This number is increasing as the years pass. But research shows that 30% of all hearing losses are caused by excessive exposure to loud noises and is very much preventable. So, how exactly do we protect our ears? Here are some ways that will help you protect your ears.
On a final note, remember that your ears are a very vital part of your body. It must be taken care of just like the other parts of the body.
Auditory Steady State Response (ASSR) is an objective test used for evaluation of hearing ability in children too young for traditional audiometric testing. Most children are referred for ASSR after a newborn hearing screen in the hospital indicates the possibility of hearing loss. Early intervention strategies, such as hearing devices or cochlear implantation, are necessary for development of speech and language skills in a child with hearing impairment. The results obtained from ASSR testing can be used to estimate the behavioural pure-tone audiogram. This information is essential in the management of children with hearing loss.

Auditory brainstem response (ABR) Audiometry is a neurologic test of auditory brainstem function in response to auditory (click) stimuli. First described by Jewett and Williston in 1971, ABR Audiometry is the most common application of auditory evoked responses. Test administration and interpretation is typically performed by an audiologist. (Neil Bhattacharyya, MD, Jan 21, 2009, http://emedicine.medscape.com/article/836277-overview)
The primary purpose of Otoacoustic emission (OAE) tests is to determine cochlear status, specifically hair cell function. This information can be used to (1) screen hearing (particularly in neonates, infants, or individuals with developmental disabilities), (2) partially estimate hearing sensitivity within a limited range, (3) differentiate between the sensory and neural components of Sensorineural hearing loss, and (4) test for functional (feigned) hearing loss. The information can be obtained from patients who are sleeping or even comatose because no behavioural response is required.

This test involves the presentation of a continuous tone to determine whether the threshold for the tone has changed (becomes poorer) over time. The test helps differentiate sensory from neural hearing loss, and is used in the diagnosis of cochlear versus retro cochlear lesions and eighth nerve tumours. While this test is still in use, the auditory evoked potential test is largely used in place of the tone decay test.
Behavioural test methods include Visual Reinforcement Audiometry (VRA), Conditioned Play Audiometry (CPA), and Conventional Audiometry. The goal of all testing is to determine the softest levels of tones and speech that a child can hear. The softest sound a child can hear 50 percent of the time, is called a “threshold”.
