The noise level that can cause permanent impairment of hearing ability...
Permanent Impairment of Hearing Ability:
The noise level that can cause permanent impairment of hearing ability of human beings is equal to or more than 120 dB.
Explanation:
Exposure to loud and continuous noise can lead to noise-induced hearing loss. The intensity of sound is measured in decibels (dB). The World Health Organization (WHO) recommends that exposure to noise levels above 85 dB should be limited to a maximum of 8 hours per day to prevent hearing damage.
When the noise level exceeds 120 dB, it can cause immediate and permanent damage to the ear. Such high-intensity sounds can damage the hair cells in the inner ear, leading to noise-induced hearing loss. This is because the hair cells are responsible for transmitting sound signals to the brain, and once they are damaged, they cannot be repaired or replaced.
Examples of sounds that can reach 120 dB or higher include firearms, explosions, jet engines, rock concerts, and heavy machinery. Prolonged exposure to such sounds can lead to permanent hearing loss.
Conclusion:
In conclusion, the noise level that can cause permanent impairment of hearing ability of human beings is equal to or more than 120 dB. It is important to protect our ears from loud noises by wearing earplugs or earmuffs when in noisy environments and limiting exposure to loud sounds.
