Noise-Induced Hearing Loss Affects Certain Frequencies, Preventing The Understanding Of Words    

It Can Be Avoided Wearing Earplugs That Lower The Volume    

Noise-related hearing loss is caused when the small hair cells inside the inner ear are affected and unable to covert the sounds into electrical signals to be recognized by the brain. These hair cells are tuned for certain frequencies. Therefore, this condition prevents hearing the frequencies matching to the damaged cells. Usually, the higher frequencies are affected, which also correspond to the consonants, making the process of understanding a conversation more difficult, hearing the speech without being able to determine the words. Also, excess noise can vary the threshold in a person’s hearing which is the lowest decibel level at which a person can hear a specific frequency. These can be temporary or permanent, as in the case when there is gunfire or an explosion, where there is a temporary hearing loss. Another consequence may be the appearance of tinnitus, which is a ringing in the ears or other sounds, such as hissing or clicking, which are not in the environment. One way to prevent it is by wearing hearing protection, which consists of earplug that will lower the volume. More Information click here.
