Analysis and control of noise in a textile factory

Abstract

Increased noise level with the technological advancement becomes a serious problem in the textile industry and it has become a crucial occupational hazard to its workers. Maximum noise level of some textile machines is as high as 95dB and locating many machines inside a single room causes to increase the cumulative noise level by at least 5dB beyond maximum noise level of a machine. So the noise level inside a textile factory is well above the limits specified by NIOSH and it amounts to be hazardous. This article analyzes the quality of noise and its distribution inside the factory. A mathematical model is developed to predict the noise distribution pattern and the model is validated with the noise data gathered following the standard methods. Economically viable noise control panels are designed and carry out a pilot implementation in order to prove the effectiveness of the noise control method experimentally. Further, authors present the potential applications of the proposed design and evaluate its usefulness.
