Comparison: Sounds In Decibels
In this comparison video we look at the magnitude of sounds measured in decibels! Sound is measured in units called decibels (dB). The higher the decibel level, the louder the noise. On the decibel scale, the level increase of 10 means that a sound is actually 10 times more intense, or powerful. Do you what the loudest sound ever recorded is ...

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
