Select the correct answer from each drop-down menu. The decibel level of a normal conversation, which has an intensity of 3.2 x 10^-6 watts/m2, is dB. If the decibel level goes up to 80, the intensity of the sound will be watts/m2. Use the formula , where is the sound level in decibels, I is the intensity of sound you are measuring, and is the smallest sound intensity that can be heard by the human ear (roughly equal to watts/m2).
