It is accepted than the most humans can hear from 20 Hz to 20,000 Hz.
Of course it depends on the exact person because there are so many variables to consider in this topic. In fact, most humans are unable to hear in these limits. Older people hears less than young people.
By the way, the CD audio is coded at 44,100 Hz due to this fact. There is a theorem (Nyquist theorem) which establishes that any wave can be sampled and recover without loss if you use a sampling of 2 times limit frequency. Due to the fact that humans hears only until 20 kHz, 40 kHz is enough for sampling.
For waves the unit of one wave cycle per second is Hertz
There can be any number. Cycles per second are referred to as Hertz
Two people die per second. :(
Hertz (Hz) is the SI unit of frequency, equal to one cycle per second.
2000 cycles per second can also be referred to as 2000 hertz(HZ). This can be found by using the conversion of 1 Hz=1 cycle/second.
Dogs can hear sounds with frequencies up to 65,000 vibrations per second, which is higher than what humans can hear. While they may not be able to hear a sound with exactly 75,000 vibrations per second, they have a wider range of hearing than humans.
Humans can usually here sounds from about 20 to 20,000 HZ. (cycles per second) Women and children can hear better than men.
Hertz is another term for cycle per second. It represents the frequency of a periodic phenomenon, such as a wave or vibration, and is defined as one cycle per second.
For waves the unit of one wave cycle per second is Hertz
The unit for one cycle per second is called a hertz (Hz).
What you refer to is called Echolocation and is used by such creatures as Whales, dolphins, bats, some birds and shrews.
Humans can hear a sound if it has between 20-20,000 vibrations per second (hertz). The range gets smaller for old people. Any sound outside of this range can't be heard.
One Megahertz is one million cycles per second.
There can be any number. Cycles per second are referred to as Hertz

Hertz (Hz) is the SI unit of frequency, equal to one cycle per second.
One hertz is one cycle per second... A megahertz is 1 million cycles per second
