Abstract

Noise is one of the most found physical contaminants in the manufacturing Industry. Professional deafness or even permanent hearing loss may produce due to most negative effect caused by noise exposure. It also produce ill effects on people’s health, since basic activities such as sleeping, resting, studying and communicating etc. are highly affected. It endures high environmental pollution. We have collected different noise related parameters like Leq (Equivalent sound level), Lav (Average sound level), LAE (Sound exposure level) and TWA (Time Weighted Average level) from different machines used in an industry, especially power press machine, grinding machine etc. We propose a noise exposure minimizing technique with the help of Karnaugh map which is generally used in Boolean algebra simplification. By implementing Karnaugh map technique, different noise exposure parameters are minimized, and maximum sound exposure sources are identified.
