WebFeb 23, 2024 · To understand what dB means, remember that it is a ratio used to compare and calculate levels of power change. Unlike voltage or current, which are measured in volts and amperes, respectively, the decibel is a dimensionless quantity. If you need to find sound intensity levels in decibels, look at our dB calculator. WebThe decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). ... dB SIL dB sound intensity level – relative to 10 −12 W/m 2 dB SPL dB SPL (sound pressure level) – for sound in air and other gases, relative to 20 μPa in air or 1 μPa in water

WebReference sound intensity I0 = 1 × 10 −12 W/m 2 ≡ 0 dB Sound field sizes: sound pressure, particle velocity, particle amplitude. Field sizes, such as the sound pressure are always expressed in RMS. This is mainly proportional to the electric voltage V. Sound energy sizes: sound intensity, sound energy, sound energy density, acoustic power. WebThe decibel scale is logarithmic, which means that loudness is not directly proportional to sound intensity. Instead, the intensity of a sound grows very fast. This means that a sound at 20 dB is 10 times more intense than a sound at 10 dB. Also, the intensity of a sound at 100 dB is one billion times more powerful compared to a sound at 10 dB.
