The human body is influenced by a lot of interdependent factors of natural and socioeconomic origin that determine its health. The environment is a factor with a particular impact on the state of health, influencing the occurrence of multiple diseases, such as: chronic respiratory deseases, cardiovascular, allergic, endocrine, metabolic, psychological and neoplastic disordes. In this group of health determinants can be included: the quality of air, water, soil, food, workplace, living area and physical factors such as: noise and radiation. An important factor in the pollution of the environment, currently, has become noise, a real scourge, a form of pollution much more damaging and with much more serious effects than numerous other pollutants. Communal noise assaults people's ears with an intensity close to the level that produces permanent hearing damage. Around the airports, the intense noise of the planes "bombards" people’s ears of the area, producing them not only discomfort, but even otic injuries, somatic and mental disturbances. Numerous workers are exposed to noise not only in heavy industry, transport, but even in agriculture. The effects of noise on the body depend on three variable elements: sound intensity, frequency and duration of exposure. The purpose of this paper was to determine the impact of noise pollution on the environment and human health. The researches took place in the city Chisinau with different areas of the intensity of public transport and atmospheric noise pollution. Sonometric determinations were made regarding the evolution in time of the street noise level on the main traffic arteries in the municipality of Chisinau; as well as at the train departure and arrival stations. The most intense sources of noise are those with a sound intensity over 100 dB. One of the regions with major noise pollution is the area of the railway station, which produces negative effects on the health of the population in that area. In such a way, on the road Muncesti in Chisinau, the noise caused by railway transport beats the normative levels, which requires compliance measures on the protection of the population from the influence of railway noise. Also, the sonography results on the streets of Chisinau also determined high noise pollution also in the streets Ion Creangă, Alba-Iulia, Grenoble, Ștefan cel Mare, Dacia and Moscovei. Therefore, it was found that the people who live on these streets more often have dysfunctions of the hearing aid, as well as of the nervous system, influencing most of the homeostatic indices. Clinical and audiometric research on exposed subjects to noise has demonstrated a decreasing of hearing acuity as a result of damage to the cells that transmit sound from the ear to the brain. Based on the given study, it is recommended to amelioration noise pollution by: planting trees along the crowded arteries of the municipality; redirection of heavy transport to peripheral areas; location of car and railway stations in less crowded areas; as well as the creation of sound-absorbing surfaces that lead to a relative reduction of the noise level both in the case of the noise produced in the respective spaces and the one coming from outside them.
