Sound question

  1. Jun 4, 2004 #1
    I have a question. If there are 2 (only 2) big speakers at opposite ends of an outdoor stadium, will the sound be good? Can you explain this in terms of physics. Thank you!

    As the sound waves pass by eachother they will creating what is called a standing wave. What will happen is there will be places in between the speakers where the two waves will cancel out (remember sound waves are just changes in pressure in the air) and will create dead spots (where no sound will be heard). However, there will are also points where the waves will have constructive interference and the sound will be amplified.
