Answer :
The least intensity is necessary for the frequency of about 3000 Hz.
The ear may react to a huge variety of intensities. The lowest intensity that the human ear can pick up at 3000 Hz is around [tex]10^-16[/tex] W/cm². A sound's maximum acceptable volume is at [tex]10^-4[/tex] W/cm². The threshold of hearing and the threshold of pain are the two extremes of the intensity spectrum, respectively. The eardrum and the ossicles may get permanently damaged by sound levels that are above the threshold of pain.
A sound that is a million times louder than another does not cause the ear to perceive it as louder by a million times. This is because the ear does not respond to sound intensity linearly. The ear's reaction to intensity is more akin to a logarithmic function than a linear one.
