High-intensity music, loud sounds in bars, factories, lawn mowers, etc. can cause severe damage to the ears, leading to hearing loss.
According to the Centers for Disease Control (CDC), noise-related hearing loss, which affects about 17 percent of adults, is the result of repeated or excessive exposure to noise. Damage to the ear it does not depend on the loud or low sound but depends on the type of sound waves affecting the ear structure.
Hearing loss occurs when any part of the ear or the nerves that transmit sound information to the brain don’t work the way it should. In some cases, hearing loss can be temporary. However, it can become permanent when vital parts of the ear are damaged beyond repair. Damage to any part of the ear has the potential to lead to hearing loss.
Loud noises are especially harmful to the inner ear (cochlea). One-time exposure to very loud sounds or listening to loud sounds for a long time can cause hearing loss. Loud noise damages the cells and membranes in the cochlea. Listening to loud noises for a long time causes the hair cells in the ear to overwork and the cells to die. Hearing loss will worsen with continued exposure.
In everyday life, some noise becomes a risk that leads to permanent damage to the cochlea or the cellular structures of the inner ear.
The sound level of concerts, nightclubs and bars can reach 120 dB or more. Ear damage can occur after 9 seconds of exposure to 120 dB sound. Therefore, people should wear protective equipment to shield their ears from exposure to excessive noise.
Loud sound at construction sites, factories
Mixed sounds from construction sites and factories are also factors that cause damage to the ears. Tools such as drills, compactors, noise from excavators, demolition of broken houses all threaten the hearing of the exposed person. Noise exposure at 85 dB over an 8-hour period is considered hazardous. Most noise-induced hearing loss is the result of cumulative damage from repeated exposure to hazardous noises.
Therefore, using ear protection that helps to reduce noise levels is a must for those exposed to excessive noise in workplaces such as construction sites or factories.
Lawn mower sound
With a decibel rating of 90 dB, if a person has to listen to the noise from the lawn mower for more than 3 hours continuously, their ears will be damaged. Therefore, lawn mowers should wear ear protection when using lawn mowers, leaf blowers, log splitters and power tools. People who accidentally hear noise from lawn mowers should also take note, cover their ears and find another place to temporarily stay away from the noise.
Remember to avoid listening to music while mowing or using similar tools as this increases the risk of hearing loss. People often turn up the volume of their music to overcome the noise of the lawn mower, mixing a variety of noises makes the sound very dangerous.
Firearms include firearms in games, guns for competitive athletes, and firearms as well. The gun produces a sound level of up to 140 dB so a single shot from the gun can cause severe damage to the ear. Hair cells in the cochlea are damaged, causing sensorineural hearing loss, which cannot be restored. Ear protection is a must when using a gun.
Harmful effects may continue even when noise exposure is stopped. Damage to the inner ear or the auditory nervous system is generally permanent. Noise can damage the auditory nerve that carries information about sound to the brain. The effect may not show up on the hearing test at first but it creates ‘hidden hearing loss’ that makes it difficult to understand speech in noisy places.
In addition to reduced sensitivity to sound, noise-induced hearing loss also causes symptoms such as a feeling of fullness in the ears, muffled noises, tinnitus, etc. The degree of damage to the ears caused by sound Excessive noise is defined by the length of time a person is exposed to loud noise, the volume of the noise, and the degree to which the ears rest between exposures. The louder the sound, the shorter the duration of hearing loss.
