Why Loud Noise Causes Hearing Loss - Hearing Loss Treatment
Why Does Loud Noise Cause Hearing Loss?
Since the onset of the Industrial Age in the late 1800s, the world has become an extremely noisy place. The invention of automobiles, factory machinery, radios, television, and construction equipment quickly replaced the quiet sounds of nature and the silence of rooms without entertainment centers or huge computer monitors blaring the latest Netflix film. Since our ears did not evolve in such a cacophonous setting, they do not endure well under the constant barrage of loud noises emerging from our homes, our workplace, and our cities.
Noise-induced hearing loss (NIHL) is a permanent condition caused mostly by prolonged and repeated exposure to noises exceeding a certain decibel level. However, NIHL can happen if you are exposed to sudden and intense sounds like explosions, gunshots or other similar blasts of noise.
When extremely powerful sound waves hit the inner ear mechanism, the waves overstimulate sensitive hair cells supporting
Sound Decibels and Hearing Loss
Sound intensity, or loudness, is measured in dBs, or decibels. The decibel scale begins at 0 and extends to 180+ decibels – for example, the sound of a rocket launching if you were standing on the launch pad. Audiologists agree that continual exposure to noises over 85 decibels may eventually cause various degrees of NIHL. Factory workers were frequently diagnosed with noise-induced hearing loss before wearing hearing protection in manufacturing facilities was mandated in the 1970s.

Finally, jet engines, gunshots and other noises that sometimes cause pain within the ear will definitely kill many hair cells and could produce a noticeable and immediate loss of hearing.
Hearing Loss Treatment
The best treatment for noise-induced hearing loss is to wear hearing aids. Although Harvard scientists have recently written about successfully regenerating hair cells in mice, the ability to recreate this procedure in humans may be five or more years away. Reducing your risk of suffering noise-induced hearing loss starts with taking proactive steps toward protecting your hearing from high-decibel sounds.
When listening to music, use earbuds instead of headphones to better block intrusion of external noise that may cause you to turn up the sound. Listening to music at
Testing for Noise-Induced Hearing Loss
Traditional hearing tests involve the person sitting in a soundproof room or booth and listening to different sounds through headphones. Sounds sent through the headphones consist of a series of beeps at different decibel levels,
Results of a hearing test are presented on an audiogram. This graph shows you how well you hear soft sounds and sounds of various pitches and frequencies. After a trained audiologist interprets the results, they will explain the degree of hearing loss affecting each ear. They may also suggest obtaining hearing aids if hearing loss is moderate to substantial.
