Sonic sound emitters are one of the most effective repellers on the market today. The system emits distress calls, and, if it is a quality product, calls of predators of the target species. Effective emitters randomize pitch, magnitude, time interval and other factors to prevent birds’ getting used to them. Ultrasonic electronic devices produce high pitch emissions in ultrasound. The sound is too high pitched for people to hear, but audible to most birds. This has the advantage to preventing disturbance to neighboring households.
