Noise is a sound, especially the one that is loud or unpleasant or that causes disturbances. There are many causes for generating loud and unpleasant sounds viz, Industrialization, Poor Urban Planning, Social Events, Transportation, Construction Activities, and Household Chores. Excessive noise in working areas can influence psychological health. Sometimes it causes hearing loss, the occurrence of aggressive behavior, hypertension, sleeping disorders, cardio-vascular disease, etc.
Accidents may happen in the industry due to high noise which is generated due to the operation of compressors, generators, exhaust fans, grinding equipment. The purpose of noise monitoring is to ensure employees are protected from a high decibel (dB) of noise.
It is necessary to monitor the actual noise levels in the workplace for a periodic interval for workmen’s safety. High noise can also be generated from the faulty machinery which can be identified by periodic measurement of the noise level of that particular machine or that particular zone. Various forms and sources of sound energy can be measured, e.g. Indoor/Work Zone Noise, Ambient Noise, DG Noise, Instrument Noise, and Source Monitoring.
