ASK YOUR TEACHER With the installation of noise suppression materials, the noise level in an auditorium was reduced from 95 to 81 decibels. The level of sound ß (in decibels) with an intensity of I is B(I) = 10 log10 (I/I0), where Io is an intensity of 10-16 watt per square centimeter, corresponding roughly to the faintest sound that can be heard. Use this information to find the percent decrease in the intensity level of the noise as a result of the installation of these materials. (Round your answer to the nearest percent.) % Need Help?
