Constructions, factories, airplanes, traffic, the maritime transit of ships, wars or the launching of pyrotechnics, among others, are some of the activities considered to be the greatest noise polluters. Although it seems hard to believe, they all generate an incredible number of imbalances in all the vital cycles of Nature.
The imbalances caused by noise also have a devastating effect on our body; noise is responsible for causing discomfort, fatigue, depression, stress, loss of attention, sleep disorders, hearing impairment, neurosis, hypertension, low productivity and reduced performance; it even impairs the development of cognitive processes.
In addition to the above, noise also causes problems in other species; some animals develop complications in capturing their prey, some females reject males and marine species appear lost and disoriented, some remaining stranded or stranded on the sand.
WHO warns that one in four people will have hearing problems by 2050
More than 5% of the world's population – that is, 466 million people – have disabling hearing loss (432 million adults and 34 million children) that affect their quality of life. By the year 2050, more than 900 million people - that is, 1 in 10 - will have this deficiency.
Noise-Induced Hearing Loss Is Irreversible Exposure to loud sounds, regardless of their duration, causes exhaustion of the auditory sensory cells, resulting in temporary hearing loss or a sensation of ringing in the ears. Hearing improves as sensory cells recover, except when exposure occurs regularly or over a long period of time, sensory cells and other structures may be permanently damaged, resulting in irreversible hearing loss.
Some people may be more prone to noise-induced hearing loss than others. Genetic predisposition, chronic diseases such as diabetes, and exposure to tobacco smoke are known to increase the risk of noise-induced hearing loss. Since we cannot know who is more prone, prevention is the most effective strategy to avoid this type of hearing loss.
