An optional accessory available for the QB4 and the Bird- X Peller PRO bird repellent are Remote Extension Speakers. For the QB4 ultrasonic bird repellent. Ultrasound is cyclic sound pressure with a frequency greater than the upper limit of human hearing. Although this limit varies from person to person, it is approximately 20 kilohertz (20,000 hertz) in healthy, young adults and thus, 20 kHz serves as a useful lower limit in describing ultrasound. So in other words, you cannot hear the mount emitted, bu the birds can. Custom configurations or areas divided by walls, use up to four remote speakers to stretch sound farther. For the BirdXPeller PRO sonic bird repeller, replace the built-in speakers' sound with portable sound located to your convenience. Keep the controls close at hand, and put the remote speaker where the birds are - tree, roof, ledge, anywhere. Click either picture for greater detail.
