Abstract
In the textile industry as a whole the pattern of machine layout and operation has been changed little over the years. Banks of machines, housed in large factory areas, are crowded together to preserve floor space and optimize production in both the natural and man-made fibres industries. Noise in the mills and factories is increasing, and one of the main reasons is that in the face of keen competition and already on a 24 h basis, machines are being operated at speeds higher than ever before to increase production rates. This is possible to a greater extent with the man-made fibres; continuous threads can be produced and wound more quickly because of their inherent strength and other advantageous properties compared with natural fibres. As a direct result of the speed increase, out of balance forces and vibration increase and more energy is released as sound.
