Problem P. 4745. (May 2015)

P. 4745. The topic of a physics lesson is the decibel scale. One of the students asks the teacher whether there is an upper limit of the maximum intensity sound. The answer is ``yes, the theoretical upper limit for the intensity of sound is 194 dB''. How is this strange value gained?
