So I have this problem, every Sunday we have about 200 kids come over to our house in town, and they make a LOT of noise. We also have mildly nice neighbors that do not like noise Sunday afternoon when they are trying to watch a movie on their front porch. They live directly across the street, with only two vine-covered fences on either side of the road. They are getting somewhat fed up with all the noise, (imagine 100/200 kids yelling at the top of their lungs) and my dad had the idea that we build a brick wall to stop the sound. So my question is, how high would this have to be to be efficient, and is it worth the cost? (a 7ft wall would cost about $200-500) Or would it not work at all?

I previously posted this question as an acoustics physics question, it was closed for being off-topic, they suggested engineering as better, so I posted it here.

  • $\begingroup$ How high do they make those sound "walls" by main roads ? due to people trying to sleep who live close to roads - have you done any research? $\endgroup$ – Solar Mike Oct 27 '17 at 11:28

    $\begingroup$ @SolarMike road noise (mostly low frequency) and children yelling (mostly high frequency) are very different spectra of noise to attenuate. $\endgroup$ – ratchet freak Oct 27 '17 at 11:31
  • $\begingroup$ This is my main research, asking this question. And living in Uganda, I have never seen sound walls by main roads. If you know of any website that can help me, it would be of great help. Problem is, we do not want to spend much money on the wall. Another thing, this is my dads idea, it just sparked my interest to see if this concept would work, for us that is. I already know sound stopping walls exist, but I am asking if us makeing one would be worth the cost. Thanks for telling me what to clarify. $\endgroup$ – TimothyTuininga Oct 27 '17 at 11:34
  • $\begingroup$ @ratchetfreak so wall or move the children?? I wanted to know what the OP had found so far.... $\endgroup$ – Solar Mike Oct 27 '17 at 11:35
  • $\begingroup$ This is just am idea, I want to know if it is practical. (I know it's possible) Moving the children is not possible in this case. $\endgroup$ – TimothyTuininga Oct 27 '17 at 11:37
