people the noise is a very glistery noise you could find it at bamboo gardens i found it there
The frequency range for human audible sound is 20 Hz to 20,000 Hz.
20 Hz to 20,000 hz is the recognized range.
The range of frequency of sound that coal trains emit when moving hovers around 20 Hz to 20,000 Hz
The frequency of vibrating pendulum lies below the audible range (20 Hz to 20,000 Hz)
For the human ear, sound is audible in the range of 20 Hz (Hertz) to 20000 Hz. Sounds below 20 Hz are "infrasonic" and have too low a frequency to be heard; sounds above 20000 Hz are "ultrasonic" and are too high a frequency to be heard.
The frequency range for human audible sound is 20 Hz to 20,000 Hz.
That is the range of audibility from 20 Hz to 20000 Hz.
20 Hz to 20,000 hz is the recognized range.
The range of frequency of sound that coal trains emit when moving hovers around 20 Hz to 20,000 Hz
typically 20-20000 Hz - but this range will decrease with age
Humans can hear with in a range of 20 Hz - 20,000 Hz. Below 20 Hz is infrasound, and above 20,000 Hz (20 kHz) is ultrasound.

Humans hear sounds best in the 1,000 to 5,000 Hz range which is where speech is centered. That is why they chose the 1,000 Hz as the test tone. Being on the lower range it is more omnidirectional and can be heard easier than any other frequency. The term Hertz (Hz) comes from the German physicist Heinrich Rudolf Hertz.
Ultrasonic and Infrasonic sound waves are waves that are not audible to human beings. The audible region contains sound waves of 16 Hz to 20,000 Hz.Infrasonic sound waves have frequencies below 16 Hz. For example, an earthquake.Ultrasonic sound waves have frequencies above 20,000 Hz. For example, x-rays.Grade 11 Physics
