During last summer in my neighborhood, a DJ had his speakers produce a very high volume of the sound, and many people had to walk away from the nice music but with uncomfortable loudness. The loudness of a sound decreases with the distance from the source of the sound. Tripling the distance from a sound source such as a DJ multiplies the relative intensity of the sound by 1/6. If the sound from a DJ has a reading of 100 decibels at a distance of 4 meters, what is the decibel reading at a distance of 12 meters?
