Abstract

Abstract Laws governing the safety and health of employed people exist in most countries of the world, the purpose being to create a suitable working environment and eliminate unsafe practices and processes. Work areas should be designed and laid out so that they are satisfactory both, from the environmental and safety points of view. In this connection, safety also implies that noise is kept at a level, which is not likely to cause hearing damage. A noise control program should involve the following: (1) The preparation of a noise map after making measurements in all areas. (2) The setting of target noise levels for all areas. 3. A description of all measures planned, a cost analysis, and the attenuation expected. 4. The setting of priorities within a plan to achieve the agreed targets, stating start and finish times. In the context pertaining to our project, we use the concept of isolating the sound at the source itself by using a canopy system. The properties of sound absorptive materials are studied and put into practice. Research has led to combining materials with good tensile strength along with its absorptive properties into one system without affecting the system performance. We get a successful drop of 15 dB with our canopy system after conducting the various tests that are present in the following chapters of this report.
