TY - JOUR AU1 - Ford, R. D. AB - Abstract Noise can occasionally be reduced at source, although this is really the job of the plant manufacturer. The user should specify acceptable noise levels, should locate the machine in the least annoying position, and should supervise the installation. Extra protection from noise may then be achieved by erecting barriers, or even total enclosures around the machine. Absorbents can be used to cut down the reflected noise and the reverberant build-up of noise, but they will not reduce directly radiated noise. If access is required through the enclosure, doors and panels should be well sealed, and permanent access for ventilation or material conveyance should be through lined ducts.
