The decibel (dB) is a logarithmic unit used to express the ratio of two values of a physical quantity. One of these values is often a standard reference value, in which case the decibel is used to express the level of the other value relative to this reference.
How Decibels Apply to Music and Sound. In music, decibels are a measurement of Sound Pressure Level (SPL). When we say the speakers at a rock concert are playing at 110dB, what we really mean is that theyâre playing at 110dB SPL. Since the decibel is only a ratio, 110dB is actually a comparison to a different number: 0 SPL.
