Top 7 Ways to Reduce Noise in Factories

This article throws light upon the top seven ways of reducing noise in factories. The ways are: 1. Noise Reduction at Source 2. This gives greatly increased flexibility to the plant layout. (iv) Other Considerations: For reducing the noise in a factory, equally important is the isolation of a vibrating source within a machine from other parts that can radiate the noise. Noise may, for


plant or mobile plant which move over a relatively small distance ( point sources), can be calculated using the equation given in BS5228 ( Attenuation =20Logd). For the plant moving over larger distances, lorries, the attenuation due to distance forms part of the equation in BS5228 ( Attenuation = 10Logd).
