As dogs hear higher frequency sounds than humans, they have a different acoustic perception of the world. [24] Sounds that seem loud to humans often emit high-frequency tones that can scare away dogs. Whistles which emit ultrasonic sound, called dog whistles, are used in dog training, as a dog will respond much better to such levels. In the ...
USVs serve as social signals, [2] and are categorized according to their frequency. Different categories of USVs are elicited in response to different situations and varying affective states. [ 3 ] The behavioural functions of USVs vary as a rat or mouse pup reaches the juvenile/adult stage of their development. [ 1 ]
It is a common understanding in psychoacoustics that the ear cannot respond to sounds at such high frequency via an air-conduction pathway, so one question that this research raised was: does the hypersonic effect occur via the "ordinary" route of sound travelling through the air passage in the ear, or in some other way?
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.

As blood temperature rises, TTS increases when paired with high-frequency noise exposure. [12] It is hypothesized that hair cells for high-frequency transduction require a greater oxygen supply than others, and the two simultaneous metabolic processes can deplete any oxygen reserves of the cochlea. [27]
Audio frequency, otherwise known as the pitch, is currently the only characteristic of sound that is known with certainty to be topographically mapped in the central nervous system. However, other characteristics may form similar maps in the cortex such as sound intensity, [ 18 ] [ 19 ] tuning bandwidth, [ 20 ] or modulation rate, [ 21 ] [ 22 ...
Violet noise is also called purple noise. Violet noise's power density increases 6.02 dB per octave with increasing frequency [8] [9] "The spectral analysis shows that GPS acceleration errors seem to be violet noise processes. They are dominated by high-frequency noise." (density proportional to f 2) over a finite frequency range.
