HEARING LOSS

It's difficult to hear or understand sounds if you have hearing loss. This occurs when one or more parts of the ear, the nerves that run from the ears, or the brain's hearing center malfunction.

Hearing loss is a condition that some people are born with. Hearing loss, on the other hand, may develop gradually over time or appear later in life. Hearing loss can run in families or be caused by birth defects, infections, or ear-damaging medications.

These types of hearing loss are unavoidable. Noise-induced hearing loss, on the other hand, is preventable. People who work in noisy environments, such as construction sites, road crews, and factories, may lose their hearing over time if they are not properly protected.

A decibel is a unit of measurement for sound levels that is commonly used in communication, signaling, and electronics. The decibel levels of some common noises are as follows:

Normal conversation levels – 60-65dB

Street traffic – 75-85dB

Motorcycles – 100 dB

Rock concerts and ambulance sirens – 120dB

Fireworks – 140-160dB

Sound from a movie theatre during action scenes – 100dB

Digital music is blasting from the speakers.– 112dB

Car horns and nightclub music – 110Db

Forklift and similar heavy machinery – 85dB

Heavy traffic or a lawnmower

From about 25 feet away, a tractor-trailer truck– 95-100dB

Chainsaw – 115-120dB

Hearing loss can show up in several ways, including:

Muffling of speech and other sounds

Requesting that others speak more slowly, clearly, and loudly regularly

Rising the television or radio volume

Withdrawal from conversations

Avoidance of some social settings

Having trouble understanding words, especially when there is background noise or when there are a lot of people around

Having trouble hearing consonants

Individuals who frequently listen to loud music with headphones while attending open-air music festivals or nightclubs, on the other hand, may be affected.

Many adults eventually notice that they're pressing the "volume up" button on the TV remote more frequently, or that a large number of people in their immediate vicinity need to speak up. While there are numerous hearing loss myths, there are two main reasons why people begin to lose their hearing:

Age: As you get older, your inner ear's tiny hair cells break down and can no longer pick up sound vibrations as well as they once could.

Noise: Exposure to a lot of loud noise for an extended period can harm the hair cells in your ears.

Damage to Hair Cells: When there is noise, hair cells bend in the same way that tall grass bends in the breeze. The more they flex, the more damage they cause to your hearing. The cells may straighten after a recovery period, but if they are too damaged, they will begin to die. In the average person's inner ear, there are approximately 16,000 hair cells. If a hearing test reveals that you have hearing loss, 30 to 50 percent of these cells have likely been damaged. This type of damage is frequently caused by noise and is This type of damage is frequently caused by noise and is usually irreversible.

Damage to the Ear Nerves: When sound vibrations strike the eardrum, the acoustic nerve, also known as the auditory nerve, transmits sound information from the inner ear to the brain. They effectively transmit sound when they work together with the middle and outer ear. Minor damage may not show up on a hearing test, but you may notice that hearing and understanding the person next to you in a noisy restaurant or crowd is becoming increasingly difficult.

Too Much Noise: Being bombarded with loud noises for an extended period can cause hearing damage. It can also happen if you're near loud, short bursts of noise, such as fireworks or gunshots. Avoiding loud noises as much as possible is the best way to avoid hearing loss.

Most types of hearing loss are irreversible. You can, however, improve your hearing by working with your physician or a hearing specialist.
