In electronics and communications, the decibel (abbreviated as dB, and also as db and DB) is a logarithmic expression of the ratio between two signal power, voltage, or current levels.
One of the most important concepts in audio is the decibel, the unit of measure denoting the ratio of a change in level, whether that level is acoustic Sound Pressure Level (SPL) or electrical signal level.Itâs abbreviated dB.As you may or may not be aware, the decibel (dB) scale is a logarithmic system, as opposed to a linear scale. Being aware of the relationships inherent in this scale is important for a variety of reasons, which will hopefully become clear by the time you reach the end of this article.tâs abbreviated dB.
