What frequency do birds not like?
ABSTRACT: Ultrasonic or high-frequency sound-producing devices are marketed as a scaring or frightening method for bird control. Although inaudible to humans, most birds also do not hear in the ultrasonic frequency ranges of above 20,000 Hz, thus the credibility of advertised claims raises questions.
What animals can hear above 20000 Hz?
Humans generally have a hearing range of between 20 and 20,000 hz, which is actually very impressive. However, elephants can hear waves as low as 14 hz, while cats can hear up to 64,000 hz frequencies, and bats can sometimes pick up noises as high as 200,000 hz.
How many decibels is too loud?
Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.
