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.
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.

What you refer to is called Echolocation and is used by such creatures as Whales, dolphins, bats, some birds and shrews.
The unit for one cycle per second is called a hertz (Hz).
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.
The animal that can hear a sound producing 75,000 vibrations per second is likely a bat. Bats are known for their echolocation abilities, which involve emitting high-frequency sounds and then listening for the echoes to navigate and locate prey. Their hearing range typically extends into the ultrasonic range, allowing them to detect such high-frequency vibrations.
One Megahertz is one million cycles per second.

One hertz is one cycle per second... A megahertz is 1 million cycles per second
