Increase In Sound Power Level Calculator

Sound power is the cause for the effect of sound pressure. The increase in sound level is the total sound energy emitted by a source per unit time. The sound power level is expressed in decibel (dB). It is often used to specify the noise or sound emitted from technical equipment like fans, pumps or other machines. Use this Increase In Sound Power Level Calculator for the calculation of sound power level increase in dB. Sound power is calculated in Wattage (W)

Formula:

I = ls + 10 x Log(n) Where, I = Increase in Sound Level ls = Sound Power Level n = No of Sources

Example

2 Sound Sources produces a sound power level of 120 dB.
Given :
n = 2
ls = 120 dB
Hence,
Increase in Sound Power Level = 120 + 10 x log(2)
= 123.0103 dB
