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.
Sounds include predator cries and distress calls of a variety of birds to discourage pest birds from coming into an area. Common locations for these devices include vineyards, reclamation plants, airports, and other open areas. There are also ultrasonic avian deterrents, which are inaudible to human ears.

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 ...
The cricket will steer itself away from the source of the sound within a very short time frame (40–80 ms). The response is evoked by brief ultrasonic pulses in the 20 to 100 kHz range, pulses that fall within the range of bat ultrasonic echolocating calls (20–100 kHz).
