Decibel Levels and Chart: How Loud Is Loud?

The range of sound intensities that the human ear can detect is so large that a special decibel scale (named after Alexander Graham Bell) is used to measure and compare sound intensities. The decibel level d B of a sound is given by d B(I)=10 log((I)/(I0)) where I0 is the intensity of sound that is barely audible to the human ear. Find the decibel level for the following sounds. Round to the nearest tenth of a decibel. Sound Intensit Intensity a. Automobile traffic I=1.58 ×10^8 ·I0 b. Quiet co
