This formula uses 1 Functions, 2 Variables

Functions Used

log10 - The common logarithm, also known as the base-10 logarithm or the decimal logarithm, is a mathematical function that is the inverse of the exponential function., log10(Number)

Variables Used

Sound Level in Decibels - (Measured in Decibel) - Sound Level in Decibels (dB) is the logarithmic measure of the ratio of a particular sound pressure to a reference sound pressure.
Pressure RMS in Micropascal - (Measured in Pascal) - The Pressure RMS in Micropascal refers to the root mean square value, it is the local pressure deviation from the ambient atmospheric pressure, caused by a sound wave.

STEP 1: Convert Input(s) to Base Unit

Pressure RMS in Micropascal: 200 Micropascal --> 0.0002 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L = 20*log10(P_m/(20*10^(-6))) --> 20*log10(0.0002/(20*10^(-6)))
