Causes of Hearing Loss and How to Avoid it

There are three major causes of hearing loss in both adults and children; the first is congenital or deformities from birth, the second is from exposure to loud noises and the other one is drug-induced. The most common hearing loss is noise-induced hearing loss. Below are the causes of these types of hearing loss and […]

How Hearing Aids Work

It is not until recent times that hearing aids are invented to help those who suffered from hearing loss. It is a medical breakthrough that enabled deaf to hear again using some concept of sound amplification. The process of how hearing aids work is fairly simple but before that let us take a closer look […]

How to Protect Your Ears?

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 […]

Auditory Brainstem Response

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)

Otoacoustic Emission

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 […]

Tone Decay

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, […]

Play Audiometry

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”. Visual Reinforcement Audiometry (VRA): […]
