It is a measure of the sound pressure level or loudness. The decibel scale is not a linear scale, it is a logarithmic scale. A doubling of your decibel reading does not mean a doubling of the noise—for every 10dB increase in sound our perception of loudness doubles. So 60dB is twice as loud as 50dB and 70dB is four times as loud as 50dB.

For example, you can listen to a noise that is 85 decibels for 8 hours …
