Audible and Inaudible sounds || What is audible range of sound?
The sounds produced in our environment can be of different frequencies. Humans cannot hear sounds of all frequencies. For example, if the frequency of the sound is less than 20 Hz (the unit of measurement of frequency), humans cannot hear it, and if the frequency of the sound is more than 20,000 Hz, it is also not audible to humans. This means that the human ear cannot hear frequencies below 20 Hz and above 20 thousand Hz. The human ear can hear frequencies of 20 to 20 thousand hertz. The frequency range of 20 to 20 thousand hertz is called an audible range of sound. So we can also say that “the range of sound frequencies that can be heard by the human ear is 20 to 20 thousand hertz.”
sounds with a frequency of less than 20 Hz are called………..Continue Reading
