The study was conducted in thirty renowned oil industries located in the selected cities of Marathawada region in Maharashtra state (Parbhani, Hingoli, Aurangabad, Jalna and Nanded) to know the inside and outside intensity level of noise. These oil industries were involved in expelling oil from cotton seeds for the last 10-12 years. All the selected oil industries were established by small and medium entrepreneurs. Measurement of noise level was made with a handy sound level meter (model no. 2013, serial no. F 04000) manufactured in India by CYGENT system. |
