Review Conceptual Example 8 as background for this problem. A loudspeaker is generating sound in a room. At a certain point, the sound waves coming directly from the speaker (without reflecting from the walls) create an intensity level of 78.1 dB. The waves reflected from the walls create, by themselves, an intensity level of 70.9 dB at the same point. What is the total intensity level? (Hint: The answer is not 149.0 dB.) Number i Units
