This is defined as 0 dB. Sound pressure level, which is often abbreviated as SPL or Lp, in decibels (dB), can then be obtained using the following formula. You can click on the demo button to learn the formula. In the following chart, some sounds are expressed both linearly in ÂµPa and logarithmically in dB.
Adding Decibels. The logarithmic decibel scale is convenient calculating sound power levels for two or more sound sources. The decibel (dB) is a logarithmic unit used to express the ratio of two signal values - like power, sound power or pressure, voltage, intensity etc. - where one value is a reference value. more about decibel.
