(See chart below for sound levels for common sounds). A quick look at the chart reveals that sound level is very a different thing than sound intensity. Every extra 10 dB corresponds to a sound that is ten times more intense than before.A decibel (dB) is a tenth of a Bel (“deci-Bel”). It is a relative unit of measurement used to express the ratio of one quantity to another on a logarithmic scale. Decibels are commonly used in audio to define gain, sound pressure level (dB SPL), signal level (dBv, dBu, dBFS), and even power (dBm).
