Question:

On the decibel scale, the loudness of a sound, D, in decibels, is given by is the intensity of the sound, in watts per meter2, and I₀ is the intensity of a sound barely audible to the human ear. If the intensity of a sound is 10¹²I₀, what is its loudness in decibels? (Such a sound is potentially damaging to the ear.)
