What will happen to the loudness of sound if the
a)amplitude of the wave is tripled?
b)distance between the source and listener is doubled?
c)density of the medium decreases?
d)wind is blowing in direction of propagation of sound?

Dear Student,
Please find below the solution to the asked query:

1) The loudness will become three times the earlier loudness since, loudness is directly proportional to the amplitude.

2) The sound will take more time to reach the listener and the more time it take the more energy it will loose and hence the loudness will decrease for the listener.

3) The density if the medium will decrease and hence the loudness which is directly dependent on the density of the medium.

4) The time taken by the sound to reach the listener will get reduced and hence the loudness will increase.

Hope this information will clear your doubts about Sound.
