\textbf{192.} If we multiply the amplitude of a sound source by 4, for a certain listening point, the sound intensity level increases by $1/3$. In this case, the sound intensity level for that listener reaches how many decibels? $(\log 2 = 0.3)$
\begin{itemize}
\item[(1)] $12$ \quad (2) $32$ \quad (3) $50$ \quad (4) $52$
\end{itemize}
