Acoustic Point Source

\epsfig{file=eps/circlegeom.eps,width=2in}

Acoustic pressure peak amplitude (or rms level) at $ \mathbf{x}=\mathbf{x}_2$ is given by

$\displaystyle p(\mathbf{x}_2) = \frac{p_1}{r_{12}}
$

where $ p_1$ is the peak amplitude (or rms level) at $ r_{12}=\left\Vert\,\mathbf{x}_2 - \mathbf{x}_1\,\right\Vert=1$

Notice that pressure decreases as $ 1/r$ away from the point source
