Question 1206719: The intensity level of sound is measured on a logarithmic scale. The intensity level, β, of sound is defined in the following equation β=10 log I/I_o where β is measured in decibels, and I_o is the intensity of a reference level. The reference level is 1.0x10^-12 W/m^2
1) What is the intensity level of a whisper if the intensity is 1.0x10^-12 W/m^2?
2) How much louder (i.e. more intense) does a siren at 30 m away, with an intensity of 1.0x10^-2 W/m^2, sound compared to a whisper?
