Which is the sound having frequency greater than 20 kHz?

ultrasonics
ultrasonics, vibrations of frequencies greater than the upper limit of the audible range for humans—that is, greater than about 20 kilohertz. The term sonic is applied to ultrasound waves of very high amplitudes.

At what frequency is the human ear most sensitive?

between 500 and 4000 Hz
Upper limits of hearing, indicating the maximum SPL that the auditory system can tolerate, are also indicated in Figure 2-2. Thus, the dynamic range of hearing covers approximately 130 dB in the frequency region in which the human auditory system is most sensitive (between 500 and 4000 Hz).

Can we hear sound more than 20000Hz?

Changes in Range Over Time With Age While the standard range of hearing for a healthy adult is between 20Hz and 20kHz, this number steadily decreases over time. This loss of hair results in a lessened ability to hear higher frequency ranges over time.

Can humans hear 22 kHz?

The commonly stated range of human hearing is 20 to 20,000 Hz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.

Can we hear less than 20 Hz?

Sound at 20-200 Hz is called low-frequency sound, while for sound below 20 Hz the term infrasound is used. The hearing becomes gradually less sensitive for decreasing frequency, but despite the general understanding that infrasound is inaudible, humans can perceive infrasound, if the level is sufficiently high.

What are frequencies below 20 Hz called?

At the other end of the spectrum are very low-frequency sounds (below 20 Hz), known as infrasound. Elephants use infrasound for communication, making sounds too low for humans to hear. Because low frequency sounds travel farther than high frequency ones, infrasound is ideal for communicating over long distances.

What is it called when the sound of frequency is below 20 Hz?

Sound at 20-200 Hz is called low-frequency sound, while for sound below 20 Hz the term infrasound is used. The ear is the primary organ for sensing infrasound, but at levels somewhat above the hearing threshold it is possible to feel vibrations in various parts of the body.
