Noise Induced Hearing Loss

Always keep in mind that if noise is loud enough and lasts long enough then it can be quite detrimental to your hearing and never get used to loud noise. Always remember that the noise induced hearing loss is not treatable because there is no medicine, no surgery and no hearing aid that can entirely reinstate your hearing after it has been damaged by noise.

If hearing damage resulting from noise then it is recognized as sensorineural hearing loss or nerve deafness. This form of hearing loss can also be caused by different factors and remember that there is no cause why noise induced hearing loss can not be abridged or prevented. When noise is too loud then it starts to obliterate the nerve endings of the inner ear and if you are exposed to longer the loud noise then the more nerve endings is being killed. Always remember your hearing decreases only when the number of nerve endings decrease because there is no likely way to reinstate life to any dead nerve endings and it means the hearing damage is everlasting. Always bear in mind that sensitivity to noise differs from person to person. If you have to scream over background noise to be heard then there is a good possibility the noise is doing damage to your hearing. Keep in mind that after being exposed to noisy or loud noise you may have ringing in your ears and have a hard time hearing.

The level of sound is systematically measured in two ways. In decibels the strength or loudness of sound is measured and the pitch of sound is measured in frequency of sound vibrations per second. Always keep in mind that a low pitched sound makes fewer vibrations per second than a high pitched sound. In sound frequency if the pitch of sound is higher then it means a higher frequency. Always memorize that human speech only ranges from 300 to 4,000 Hz.

Usually the high frequencies are the first to go when hearing loss starts because people with hearing damage usually have problem hearing high pitched voices. The loss of hearing high frequency sounds can also deform sound which makes it tricky to understand people's speech. Although it can be heard that speech often sounds stifled. With the strength of sound, the sound level ranges from the faintest sound a human ear can notice, which is labeled 0 decibels (dB), to over 180 decibels (dB). Decibels are measured logarithmically because decibel strength increases by units of 10. Hence 20 dB is 10 times as strong as 10 dB and 30 dB is 100 times as strong as 10 dB. You must always try to that wear hearing protection in extremely loud environments because unremitting exposure to noise over 85 dB could harm your hearing.
