Noise pollution is one of the causes of occupational diseases
People lose hearing more often than we can imagine. Loss of hearing or deafness today is one of the most common occupational diseases not only in Ukraine but also in the world. Every day we are accompanied by a whole range of the most diverse sources of noise - household appliances at home and in the office, neighbors repairs, televisions, the road to work - metro, people in public transport or loud headphones music. And this can not be avoided, because each of us lives in a society, co-exists with other its representatives. All our life – a global communication. Many experiments found that noise is a general biologic stimulus and under certain conditions can affect all human life systems. The influence of noise on the human auditory organ is most fully studied. Intense noise, especially at high frequencies – 4000 Hz or more, with daily exposure leads to a professional illness – hearing loss, the symptom of which is the slow loss of hearing on both ears. According to official statistics of the World Health Organization, more than 5% of the Earth's population suffers from a disabling hearing loss. That is, such loss results not only in the deterioration of hearing quality, but also has certain social consequences, namely:
- more than 360 million people around the world have hearing problems (about 328 million adults and 32 million children);
- 1.1 billion teenagers and young people are at risk of hearing loss mainly due to listening to high-volume music as well as excessive noise levels;
- more than a third of people lose hearing as a result of excessive noise levels in the workplace. The rest is congenital deafness, loss of hearing due to various diseases and injuries;
- an average of almost ten years is passed before hearing impaired people turn to a doctor;
- studies have shown that about 1/3 of people over 65 years have hearing problems.
