Decibels are a measure of sound on a logarithmic scale, where the number in front of the zero represents the number of powers of 10 (can think of as the number of zeros). As an example, a whisper is around 10 dB (power ratio of 10 / 1 zero) while a jet engine is around 120 dB (power ratio of 1,000,000,000,000/ 12 zeros). Convert the value of a washing machine at 80 decibels into a power ratio.
