Abstract
A method of and system for sonifying a portion of a given area to rid the area of unwanted pests comprising providing at least one ultrasonic point source each producing a set of pulsed signals having a randomly varying frequency in the range of about 18-30 KHz and having an intensity of at least 90 dB at the periphery of a cone shaped area extending outwardly therefrom and having a predetermined maximum length and a predetermined maximum width. The point sources are spaced in the given area to maintain the minimum sound intensity level at any point in the sonified portion at not less than 90 dB by disposing point sources opposite one another when the distance therebetween is greater the maximum length, disposing point sources adjacent one another to effect a longitudinal overlapping of adjacent cones when the room width is greater than the maximum width and disposing point sources perpendicular to the adjacent point sources to sonify any dead space therebetween.
