-If the waves propagate from the source in all 3 dimensions then we need to take in to account that  as we showed in [[phy131studiof15:​lectures:​chapter17|chapter 17]], $A\propto\frac{1}{r}$. To determine [[phy141:lectures:29&#​loudness_and_decibels|perceived loudness]] we need to remember that it depends logarithmically on intensity. I have factored these considerations in the following calculations I performed in Maple. The patterns are for two speakers separated by 1m.+If the waves propagate from the source in all 3 dimensions then we need to take in to account that  as we showed in [[phy131studiof15:​lectures:​chapter17|chapter 17]], $A\propto\frac{1}{r}$.
