please reply me
i have a doubt. if two jet planes are flying together each producing 130 db sound. then what is the level of loudness heared by a person standing there. no other parameters are known. I have two concepts in mind ie) 1. every fundamental frequency produce hormonics and when two similar sin waves travel together they form a single sin wave. 120 db sound is threshold of pain.i don't know whether this concept is useful or some another concept is there please explan it.
thanks in advance
