Question

A vibrating body should oscillate minimum how many times per second to make a audible sound for humans??​

Answer 1

Answer:

20 times

Explanation:

the audible range of frequencies for human is between 20 hz to 20000hz so minimum is 20 hz = 20 vibrations per second hope this helps pls mark as brainliest

Answer 2

A vibrating body should oscillator for minimum 20 times per second to make an audible sound for humans.

• The human can hear the sounds which have frequency in the frequency range of 20Hz to 20kHz.

• So,the minimum frequency which human can hear is the sound of frequency 20Hz.

• Which means,the object has to oscillate for minimum 20 times in a second to become audible for the human ears. (Because, 1 Hz frequency means 1 vibration per second.)
