Use the following information to answer question 32 The equation that defines the decibel level for any sound is L 10log( where L - loudness in decibels I -intensity of sound being measured 1, intensity of sound at the threshold of hearing 32. Given that a vacuum cleaner is 10 000 000 times as intense as Io then the loudness of a vacuum cleaner is A. 120 decibels B. 90 decibels C. 70 decibels D. 20 decibels Solve the equation 2- nearest hundredth. algebraically. Show all your work and round your final answer to the

Explanation / Answer

Hi
32. Given Intensity = 10,000,000 * I0
substituting in the formula we get
Loudness = 10 log (10,000,000) = 70 decibels
?
