The decibel level of a sound is given by the equation D = 1010810 ( where / is the sound's intensity and lo corresponds to the intensity of the weakest sound that can be detected by the human ear. A sound of 140 decibels produces pain in the average human ear. Approximately how many times greater than / must the intensity / of a sound be to reach this decibel level? A. 22026 times greater B. 14 times greater
