Yes, factories are one of the prominent sources of noise pollution and if they are built-in industrial areas, they have to make sure that the permission noise limit does not exceed:
|Area or Zone||Limits in dB(A) Leq* (Day Time from 6.00 am. to 10.00 p.m)||Limits in dB(A) Leq* (Night Time from (10.00 p.m. to 6.00 a.m)|
If any employee faces hearing loss1 after working in a factory, then any doctor who detects this must inform the chief inspector of factories with the details of the employee.
