Today there is large growth in industrialization; therefore industrial noise has become a big environmental Problem. The noise that is generated by machines in industries is termed as industrial noise. This noise interferes with communication between supervisors and staff. Continuous exposure to noise can cause fatigue, which often results in accidents and reduces the pace and quality of work. Noise affects negatively on the day today life of surrounding people, who have faced with many problems mentally and physically. Workers are exposed to continuous noise throughout the workday, might results in some injuries such as hearing loss (temporary or permanent), weakness in nerves, pain in internal tissues, heart problems, and even higher blood pressure in long term. It is seen from the experimentation that a long exposure to noise over 85 dB might be a dangerous factor for high blood pressure (BP), and it may induce major problems amongst the sensitive individuals and hence more focus is required on noise control. Therefore, noise control is one of the major requirements to improve the living environment. Developed countries use sensible techniques to reduce the nuisance barrier walls, soundproof curtains, duct, acoustic panelling, sound enclosures for industrial machinery and different similar noise management treatments that area unit put in close to the supply to effectively cut back the sound level. However, India has not however yielded a lot of into this issue as noise reduction strategies area unit expensive. Therefore, it is necessary to find out cost effective methods to control industrial noise. This study emphasizes the vital role of algae dust, bamboo leaves, Coconut Coir Fiber, saw wood dust etc as natural sound reduction material, to give a solution for the existing industrial noise problems and also aimed to identifying the best practices in industries.
