Does sound waves interact with each other and cancel each other out. I'm not talking about constructive or deconstructive interference either. If a strong sound source is pointed towards a weak one does the compression of air interact with other waves. I don't know if I asked it right or if anyone understands what I am trying to say. I'm wondering because from a mile away I can hear cars on a freeway at night yet I can't in the daytime. Whats the reason?
