Decibels measure intensity. If you whisper in an empty room it will measure between 0 and 1 db. This indicates the intensity of sound is minimal. This is considered the threshold of hearing.
A sound that measures 30 decibels is a 1000 times louder than the the threshold of hearing. An example of this is the noise of a regular computer produces between 20-40 dB.
