Comment on Does noise from different nearby sources 'add up'? Or do the different sources cancel each other out? In any case, please provide a formula and an example

  Two people will be about 3 dB higher, four people would be 6, eight people would increase the level by 9 dB, sixteen would be 12 dB higher and so on.

  This is only the case if they’re making identical sounds in phase with each other. The real life scenario of people walking would not scale in this way as there are too many variables. No two footsteps are the same no matter how hard you try.

    This reminded me of that one London Bridge, lol www.sciencedaily.com/releases/…/051103080801.htm

      Yeah, they were all stepping in phase with each other. Pretty cool physics going on there.
