Virtually all sounds are composed of several (or many) frequencies all going at once. Some level of harmonics on the network are acceptable and to eliminate them completely would not be practicable. The issue is to find out at what level for a particular site is an acceptable condition Good Vibrations:. Standing waves can be produced on a string fixed at both ends if the length of the string .
