|Too many decibels: a threat to health!

Havana, Cuba. – Noise stands at the top of the list of the most dangerous potential damages to health caused by environmental pollutants. Its own definition means all unwanted sounds, that is to say, rejection of acoustic phenomena by listeners. When there is no such rejection, then it is considered a sound.
Scientific studies assure that noise affects the sense of hearing; produces stress, sleeping, learning and concentration dysfunctions; and causes emotional irritation. It also causes cardiovascular disorders that show in rising blood pressure and heart attacks.
On the other hand, noise is not only detrimental to health. Sound abuse, even if fully accepted, can be very harmful.
A common example is loud music heard in headsets at more than 120 decibels, a blare comparable to the environmental noise caused by an airplane. Moreover, young people have died in accidents, having failed to hear the horn of a car because of the shrill of these modern devices.
According to the Journal of the American Medical Association, the loss of hearing is not necessarily part of the natural aging process. The great majority of the cases are preventable.
It is no secret that frequent exposure to high acoustic energy, whether noise or sound, causes serious damages to the sense of hearing and deprives human beings of its useful performance.
Let us reward our priceless hearing with comfortably perceptible sounds. Let us stay away from acoustic pollution for as long as we can. Finally, let us refrain from abusing our hearts, because they cannot withstand too many decibels either. Our body will certainly reward us with higher life quality. By: Laura E. Perez
