Abstract: Railway is considered one of the cheap, eco-friendly and comfortable means of transportation. They are demolishing the natural sceneries, led to death or declining the wildlife inhabitants and producing an intolerable noise. The noise produced by railway is of high frequency and sound pressure level (SPL). The peaceful sound of the park and the high speed railway noise are recoded to evaluate their SPL by the sound spectrum curves. The sound pressure level (SPL) of the peaceful environment is around 42 dB and for the high speed train running at 300 km/h has a value of about 82 dB. The noise generated by high speed railway with high SPL produced inhibition phenomenon in the growth and the production of the microbial. Also, the exposure of railway noise disturbing the routine of human beings and caused many diseases. The impacts of the high speed railway noise exposure on the microbial can be described experimentally by using acoustic chamber. Low frequency sound exposure produces positive effects while higher frequency sounds (noise) exhibit inhibition and destructive phenomenon in the growth rate of the microbial. In literature, most of the authors studied on the effects of audible sound on the microbial, but there is not much work has done to investigate the effects of railway noise exposure on them. This article presents the impacts of noise generated by railway on the human and microbial.
