You're right, it's far higher. A high frequency sonic burst could completely incapacitate someone before they could react. In the time you would have to make the lava or set up the combustion, the sound wave would have already hit you; mainly cause it moves at the speed of sound. The speed of sound is approx 340 mps which is about 761 mph. It's so fast no one could react in time.
