Sound Level in Bels Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sound Level in Bels = log10(Sound Intensity Level/Standard Sound Intensity)
L_b = log10(I/I_o)
This formula uses 1 Functions, 3 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 Bels - (Measured in Decibel) - The Sound Level in Bels refers to the intensity of sound. It is measured in bels.
Sound Intensity Level - (Measured in Watt per Square Meter) - The Sound Intensity Level refers to the logarithmic measure of the sound power per unit area, expressed in decibels (dB).
Standard Sound Intensity - (Measured in Watt per Square Meter) - The Standard Sound Intensity refers to the reference sound power per unit area, typically taken as watts per square meter.

STEP 1: Convert Input(s) to Base Unit

Sound Intensity Level: 1E-10 Watt per Square Meter --> 1E-10 Watt per Square Meter No Conversion Required
Standard Sound Intensity: 1E-12 Watt per Square Meter --> 1E-12 Watt per Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_b = log10(I/I_o) --> log10(1E-10/1E-12)

Evaluating ... ...

L_b = 2

STEP 3: Convert Result to Output's Unit

2 Decibel -->0.2 Bel (Check conversion here)

FINAL ANSWER

0.2 Bel <-- Sound Level in Bels

(Calculation completed in 00.004 seconds)
