Noise Pollution

Industrial Noise Control

All factory premises shall abide by the maximum permissible noise limits set by NEA under the Environmental Protection and Management (Boundary Noise Limits for Factory Premises) Regulations. The noise limits become progressively more stringent when the affected premises require more peace and quiet, as well as during the evening and night. For instance, the equivalent continuous noise level from factory premises affecting residential premises must not exceed the noise limit of 70 dBA over any 5-minute period between 7am to 7pm, and must not exceed 65 dBA between 7pm to 11pm.
