Development of Ecological Criteria of Noise Control With Application of Absorbents

The operation conditions of the industrial equipment, acoustic parameters essentially depend on type of the sound field (free, diffuse or mixed). Besides the effect of the noise control of the machine itself, the field type also important, which in turn depends on the degree and quality of acoustic preparation of the workshop. The criteria is an estimation of applicability broadband absorbents, found during the current analyses, which enable to solve the problem related to the ecology of noise control at various manufacturing processes.
