Abstract:
Noise is known as an irritant both in industrial and living space settings. Also thenegative effect of noise on people’s health and wellbeing is widely recognised. Usually in thework environment the impact of noise can be easily reduced, for example, by providingpersonal protective equipment or using the appropriate administrative tools. However, inresidential areas near by to industry, the problem is quite different. Although the populationdensity in Estonia is quite low compared to other European countries, there are rural areaswhere industrial noise sources are located nearby to people’s homes.Also the awareness of noise hazard is rising among people, and company owners are forced todiminish the noise levels of production. This generates a need for knowledge about noisereduction. Current study aims to compile data about the noise emission of grain dryers withmain concern towards noise direction. Results of the study can be applied in developing layoutsof grain dryers or in noise barrier development.Noise levels around the perimeters of different type grain dryers were measured with a TES-1358A sound analyser in 1/3 octave band segregation. Measurement data was compiled intonoise maps. Specifications of Estonian laws were taken into account. Key words: grain dryer noise, noise emission, non-occupational noise.
Key words:
grain dryer noise, noise emission, non-occupational noise
