What is the maximum sound level?
Under normal atmospheric conditions the maximum sustained sound level achievable on earth is 194 decibels. The reason for this is that the oscillation of the sound wave can not drop below a vacuum created by the sound pressure in air. However, peak sound levels can achieve levels substantially higher than 194 decibels. One incredible example of this would be the volcanic eruption in Tambora, Indonesia in 1815 which ejected 36 cubic miles, equivalent to a 14 gigaton nuclear bomb based on ejected volume. The internal pressure is believed to have been 47 million pounds per square inch resulting in a measured peak decibel level of 347 dB. Click here for a chart of typical noise values.
