ultrasonic
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.
Studies show humans can hear up to 300 WPM with full comprehension, although most audio books are at about 150-160 WPM.
These are frequencies less than 20 Hz (cycles per second) which represent sounds that most of us cannot hear. More information is available on the wikipedia article about infrasound.
When you see those fractions on paper and you read them, you say "two fifths" and "three fifths". When you hear that, you immediately realize that three of anything is always greater than two of the same thing.
It is not uncommon to hear professional athletes state, fervently if not logically, that they are giving "110 percent."
the range of sound frequencies that humans can hear is about0to200Hz
Assuming you mean the lowest frequency humans can hear, that's about 20 Hz.
20 Hz.

Humans can hear sounds of 20 to 20,000 Hz. Hearing is best in the middle part of this range. However, the acuity varies between individuals and changes with age so that there is no specific frequency at which humans hear best.
Humans are able to hear infrasound, depending upon frequency and amplitude.
Most animals can, but dogs can definitely hear them.
I think so, they also hear higher frequency sounds.
A higher frequency.
It depends on the type of animal. Dogs can hear a higher frequency than humans, which is the concept behind a dog whistle. Elephants can hear lower sounds than humans.
because of more efficient hearing power than humans and it is because of the frequency.
An ultrasonic wave is a sound pressure wave that has a very high frequency. The frequency is higher that what humans can hear.
