You are at a rock concert, standing 11.9 m from one of the loudspeakers. Based on the pain in your ears, you estimate the decibel level to be about 102 dB at this location. You are worried that this intensity level may be harmful to your ears and result in a degradation of your hearing in years to come, so you want to move farther away from the loudspeaker to reduce the sound to a "dull roar" at a decibel level of 82.7 dB. From your present location, how much farther away from the loudspeaker would you have to move to reach this reduced decibel level?
