There are many interesting problems we can create in the study of waves, for instance, in problems related to sound and earth quake intensities. This problem is the following: Someone's whisper has a sound level of 15 decibels, while the sound level of a noisy pep rally in a gym can reach 105 db. In theory, how many whispering people must be accommodated in a gym in order to reach a sound level equivalent to a pep rally?
