Need Help? Submit Answer ARHSCALC1 5.2.062. Read It MY NOTES With the installation of noise suppression materials, the noise level in an auditorium was reduced from 95 to 81 decibels. The level of sound 3 (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.
