ABSTRACT

Selection of Quiet Processes In many cases no feasible alternatives have been found for common and important noise processes, in which case the question may not arise. However, there are cases when there is a choice of method or process, in which case the noise factor should be included with the others at an early stage. Clearly noise is not the only factor but must be given due consideration. If the choice of one process is going to result in an expensive noise control bill at a later stage, this should be included when an initial cost comparison is made. This may show that an apparently more expensive but quieter process may turn out to be cheaper in the long run.
