No. Ultrasonic sound is directional, very much like a torch beam. We sell two variations of the Sentinel ultrasonic repeller. One has a single speaker and the sound travels in only one direction. The other sentinel unit has a speaker pointing to the left, two pointing to the front and one pointing to the right which gives about 300 degrees of coverage.
