I think they(longitudinal waves)hits the air,but they are not reflected back because air is very light.In the same way,when they hit a wall,as the wall is not going to vibrate vigorously,Some of the waves are absorbed(i.e. they make the wall vibrate)and the others are reflected back.
If I am right,I don't understand why the wall reflects others back.
Can you help please!
