A speaker emits 3.00 W of sound.

(a) What is the sound level in decibels for an observer that is 6.00 m away from the speaker?

(b) Suppose the volume was turned down so that the speaker only emits 1.00 W. If the observer remains the same distance away from the speaker, what is the new sound level in decibels in this case?
