In Environmental Engineering (Fourth Edition), 2003. Industrial Noise Control. Industrial noise control generally involves the replacement of noise-producing machinery or equipment with quieter alternatives. For example, the noise from an air fan may be reduced by increasing the number of blades or the pitch of the blades and decreasing the rotational speed, thus obtaining the same air flow.
