The today’s socio-physical needs demand for conducive acoustical environment for living & working, than never before. In the industrial areas, awareness regarding the noise reduction & control is increasing day by day. According to ASHREA, it’s mandatory for all the industries to maintain noise below the certain levels. In this paper, study has been carried out on barrier design to reduce the noise level at the receiver, for any type of fin tube heat exchanger. In this method, noise is treated along the path. The paper includes mathematical calculations for noise in fin tube heat exchanger with and without barrier. A C++ program has been coded to eliminate substantial amount of manual calculations & possibility of error associated with it and to have speedy of calculations. A case study is presented in this study where barrier design results in nearly 15 dB noise reduction.
