Answer 2

Question:

Human ear can not hear sounds of frequency less than ..

$\mathsf{human \: ear \:can \: not \: hear \: a \: sound \: less \: than \: \red{20hz}}.$

Although this range of hearing is flexible on the basis of age and surrounding condition . our ear is so small to take all the sound waves inside it . when a sound is releases it goes through several layers and stages to pass through our ears , being a sound less than 20 Hz cannot work because it can't reach our ear .

the healthy range in which a human can hear is 20 to 20,000Hz .

people loos this range with growing age.
