@ShailKumar
What sound level corresponds to the threshold of human hearing?

120 dB
0 dB
80 dB
20 dB

Answer 1

Not sure what to do

Answer 2

The threshold of hearing is frequency dependent. Take it 0 db for 1000Hz

Answer 3

So only 20 is in range of 20 to 20000

Answer 4

Would 0and 20 b right

Answer 5

20Hz to 20 KHz is the frequency range. Sound level in db is energy per unit area. 0 db is the threshold of sound level for humans.
