The Decibel (dB) Scale & Audio Rules 101 | Audioholics
https://www.audioholics.com/room-acoustics/the-decibel-db
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. It’s abbreviated dB. As you may or may not be aware, the decibel (dB) scale is a logarithmic system, as opposed to a linear scale.
Decibel Definition & Meaning - Merriam-Webster
https://www.merriam-webster.com/dictionary/decibel
Definition of decibel. 1 a : a unit for expressing the ratio of two amounts of electric or acoustic signal power equal to 10 times the common logarithm of this ratio. b : a unit for expressing the ratio of the magnitudes of two electric voltages or currents or analogous acoustic quantities equal to 20 times the common logarithm of the voltage or current ratio.

Sound is measured in units called decibels (dB). The higher the decibel level, the louder the noise. On the decibel scale, the level increase of 10 means that a sound is actually 10 times more intense, or powerful. Share this: Source 1, Source 2, Source 3.

The decibel (dB) is a logarithmic unit used to measure sound level. It is also widely used in electronics, The dB is a logarithmic way of describing a ratio. intensity or several other things. Later on we relate dB to the phonand to the sone, which measures loudness. But

Decibel (Symbol: dB) is a logarithmic unit that indicates ratio or gain. Decibel is used to indicate the level of acoustic waves and electronic signals. The logarithmic scale can describe very big or very small numbers with shorter notation.
Decibel (voltage) (dBV) | RecordingBlogs

A voltage decibel (dBV) is a unit of measurement of the ratio of an amount of voltage V to V 0 = 1 volt given by the formula 20 log 10 (V/ V 0) = 20 log 10 (V). For example, the consumer audio level of -10 dBV means -10 = 20 log 10 (V) and so V = (10^ (-10/20)) = 0.31623 volts approximately.

The Decibel A Scale (dBA) is a logarithmic system of measuring sound as the human ear experiences it. The scale assigns a weight to the decibel value of sound based on the sensitivity of the ear at a particular frequency. The scale is calibrated in units called A-weighted decibels or dBA for short.

TechTarget Contributor. A-weighted decibels, abbreviated dBA, or dBa, or dB (a), are an expression of the relative loudness of sounds in air as perceived by the human ear. In the A-weighted system, the decibel values of sounds at low frequencies are reduced, compared with unweighted decibels, in which no correction is made for audio frequency. This correction is …
