Control of Noise and Vibration in Recently Designed Forging Equipment

A noise may interfere with communication, diminish hearing, and affect health and even behaviour of human beings. Continuous exposure to loud noise for a fairly long time may produce permanent hearing loss. The approximate sound levels for jet plane take-off and rocket engine are 150 dB and 180 dB respectively and such sound levels are considered as painful. In a forge shop the noise level could be reduced by 20 dB with the idea of improving communication and to protect the health of the employee working in the forge shop. The noise problem should not be neglected as industrial workers exposed to over 115 dB of sound for eight hours daily would become "totally" deaf in a few years.
