\subsection{Wave Leakage Time}  {\bf  The wave leakage time scale $t_{\rm leak}$ on which wave energy tunnels from the acoustic cavity into the stellar core can be calculated several ways. As shown above,  \begin{equation}  \label{eqn:tleak}  t_{\rm leak} \simeq \big( \Delta \nu T^2 \big)^{-1} \,,   \end{equation}  where $T^2$ is the fraction of the wave energy that leaks into the core each time the wave hits the outer edge of the evanescent region at $r_2$. Using a WKB approximation, the value of $T$ can be calculated from the first part of equation \ref{integral}, or a rough estimate can be made using equation \ref{integral2}.    }
