Abstract
Some manufacturing processes are accompanied by significant noise and vibration. Sources of intense noise and vibration are machines and mechanisms with unbalanced rotating masses, as well as technological installations and apparatuses in which the movement of gases and liquids occurs at high speeds and has a pulsating character. The modern development of technology, equipping enterprises with powerful and fast-moving machines and mechanisms leads to the fact that people are constantly exposed to noise of increasing intensity. Increasing noise and vibration in the workplace has a harmful effect on the human body. As a result of prolonged exposure to noise, the normal activity of the cardiovascular and nervous systems, digestive and hematopoietic organs is disturbed, and professional hearing loss develops, the progression of which can lead to complete hearing loss. Among industrial hazards, noise and vibration occupy one of the leading places among production hazards. The harmful effects of increased noise levels on the human body are well khown, therefore, the relevance of this problem is obvious.
Highlights
In production conditions, a variety of machines, apparatus and tools are sources of noise, vibration.Noise and vibration are mechanical vibrations propagating in gaseous and solid media
One of the areas of noise control is the development of state standards for vehicles, engineering equipment, household appliances, which are based on hygiene requirements to ensure acoustic comfort
Permissible levels and measurement methods ”establishes noise characteristics, methods for their measurement and acceptable noise levels of cars of all samples accepted for state, interdepartmental, departmental and periodic control tests
Summary
A variety of machines, apparatus and tools are sources of noise, vibration. Noise and vibration are mechanical vibrations propagating in gaseous and solid media. Noise and vibration differ in frequency of oscillations. Noise is an erratic combination of sounds of different strength and frequency; able to have an adverse effect on the body. The source of noise is any process that causes local pressure changes or mechanical vibrations in harsh, watery or gaseous media. Sources of noise can be engines, pumps, compressors, turbines, pneumatic and electric tools, hammers, threshers, machine tools, centrifuges, silos and other installations that have moving parts. In recent years, due to the significant development of urban transport, the noise intensity in everyday life has increased, because he has acquired an enormous social significance as an unfavorable factor [1,3,5,7]
