As we all know, we are always surrounded by a "sea" of sound(Of cars,air,farts etc . Lol) How can our voice be transmitted by the air without getting disturbed by other sounds? Sound is a longitudinal wave. So imagine another wave travelling perpendicular to our wave. Then at the point of intersection, there will be movement of air in both forward-backward and right-left. So the sound wave should be disturbed here. Am I wrong?
