The loudness of sound is measured in units called decibels. The decibel rating of a sound is given by D(i) = 10 - log where i is the intensity of the sound and i, is the minimum intensity detectable by the human ear (the so-called threshold sound). Find the decibel rating of each of the sounds with the given intensities. (a) Whisper, 114i, (b) Average sound level in a movie, 1010i (c) Jackhammer, 31.600,000,000i, (a) If the intensity of a sound is 114io, the decibel rating is approximately (Round to the nearest whole number as needed.) (b) If the intensity of a sound is 100lo, the decibel rating is approximately (Round to the nearest whole number as needed.) (c) If the intensity of a sound is 31.600,000,000i, the decibel rating is approximately (Round to the nearest whole number as needed.) Question Viewer Enter your answer in each of the answer boxes

The loudness of sound is measured in units called decibels. The decibel rating of a sound is given by D(i) = 10 - log
where i is the intensity of the sound and i, is the minimum intensity detectable by the human ear (the so-called
threshold sound). Find the decibel rating of each of the sounds with the given intensities.
(a) Whisper, 114io
(b) Average sound level in a movie, 10i
(c) Jackhammer, 31,600,000,000io
(a) If the intensity of a sound is 114ig, the decibel rating is approximately
(Round to the nearest whole number as needed.)
(b) If the intensity of a sound is 10ig, the decibel rating is approximately
10.
(Round to the nearest whole number as needed.)
(c) If the intensity of a sound is 31,600,000,000i,, the decibel rating is approximately
(Round to the nearest whole number as needed)
