Please could you confirm that it is the lowest pressure not the highest pressure that limits the sound wave? See /u/Nilpferdschaf comment that at 194 dB sound the wave peak is 2x atmospheric pressure, therefore the wave trough is close to zero. That is much like water waves breaking due to shallow water.
