Preface
Since the Walsh-Healy Act of 1969 was amended to include restrictions on
the noise exposure of workers, there has been much interest and motivation
in industry to reduce noise emitted by machinery. In addition to concerns
about air and water pollution by contaminants, efforts have also been direc-
ted toward control of environmental noise pollution.
In response to these stimuli, faculty at many engineering schools have
developed and introduced courses in noise control, usually at the senior
design level. It is generally much more effective to design ‘‘quietness’’ into
a product than to try to ‘‘fix’’ the noise problem in
