The non-dispersive wave propagation in air is not only important by physical means: imagine that sound incidents in different distances from the source would be composed d

Fundamentals of Wave Propagation,ated sound incidents (e.g. a child rhytmically bouncing a ball, hammers blowing at a construction site, etc.) a time-delay can easily be determined between the optical perception and the arrival of the acoustic signal which increases with increasing distance of the observer from the source.

Structure-borne Sound, the term ‘structure-borne sound’. Structure-borne sound has major importance with respect to solving noise control problems: the air-borne sound into (or from) the above mentioned solid structures is caused by motion of the structure surface. In many cases it is the structure-borne sound that is re
