Acoustic harassment and acoustic deterrents are technologies used to keep animals [1] and in some cases humans away from an area. Applications of the technology are used to keep marine mammals away from aquaculture facilities and to keep birds away from certain areas (for instance in the vicinity of airports and blueberry fields).
Ultrasonic devices are static sound-emitting bird deterrents, which, in theory, will annoy birds to keep them away from enclosed or semi-enclosed areas. Ultrasonic scarers are not harmful to birds, however, there is debate around birds' ability to hear these frequencies at loud enough decibels.
There are also ultrasonic avian deterrents, which are inaudible to human ears. [2] Ultrasonic bird repeller, 2008. In 2013, Dr. John Swaddle and Dr. Mark Hinders at the College of William and Mary created a new method of deterring birds and other animals using benign sounds projected by conventional and directional (parametric) speakers.

The term echolocation was coined by 1944 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. [1] [2] As Griffin described in his book, [3] the 18th century Italian scientist Lazzaro Spallanzani had, by means of a series of elaborate experiments, concluded that when bats fly at night, they rely on some sense besides vision, but he did ...
Electronic pest control is the name given to any of several types of electrically powered devices designed to repel or eliminate pests, usually rodents or insects. Since these devices are not regulated under the Federal Insecticide, Fungicide, and Rodenticide Act in the United States, the EPA does not require the same kind of efficacy testing that it does for chemical pesticides.
One way to improve tablet designs for birds is to use the camera on the device to have a better sense of where the bird is and adjust accordingly, or redesign the layout of a game with the parrot ...
The ultrasonic hearing is coupled to a motor response that causes evasion of the bat during flight. Although ultrasonic signals are used for echolocation by toothed whales, no known examples of ultrasonic avoidance in their prey have been found to date. [2] Ultrasonic hearing has evolved multiple times in insects: a total of 19 times.
French Lick, Indiana is Larry Bird's hometown. The city has plenty of Bird-related travel attractions.
