Sound Intensity Level Calculator

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 intensity level - (Measured in Decibel) - Sound intensity level is the level (a logarithmic quantity) of the intensity of a sound relative to a reference value.
Sound Intensity - (Measured in Watt per Square Meter) - Sound Intensity is defined as the power carried by sound waves per unit area in a direction perpendicular to that area.

STEP 1: Convert Input(s) to Base Unit

Sound Intensity: 0.00128 Watt per Square Meter --> 0.00128 Watt per Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

β = 10*log10(l/10^-12) --> 10*log10(0.00128/10^-12)

Evaluating ... ...

β = 91.0720996964787

STEP 3: Convert Result to Output's Unit

91.0720996964787 Decibel --> No Conversion Required

FINAL ANSWER

91.0720996964787 ≈ 91.0721 Decibel <-- Sound intensity level

(Calculation completed in 00.004 seconds)

Sound Intensity with respect to Sound Pressure

Go Sound Intensity = ((Sound pressure^2)/(Density of Air*Velocity of sound wave))

Density of Air given Sound Intensity

Go Density of Air = Pressure RMS^2/(Sound Intensity*Velocity of sound wave)

Sound Intensity Level

Go Sound intensity level = 10*log10(Sound Intensity/10^-12)

Power of Sound Wave given Sound Intensity

Go Sound Power = Sound Intensity*Area

Unit Area given Sound Intensity

Go Area = Sound Power/Sound Intensity

Sound Intensity

Go Sound Intensity = Sound Power/Area

Sound Intensity using Sound Intensity Level

Go Sound Intensity = (10^-12)*10^(Sound intensity level/10)

Sound Intensity Level Formula

Sound intensity level = 10*log10(Sound Intensity/10^-12)
β = 10*log10(l/10^-12)

What is sound intensity?

Sound intensity, also known as acoustic intensity, is defined as the power carried by sound waves per unit area in a direction perpendicular to that area.

How to Calculate Sound Intensity Level?

Sound Intensity Level calculator uses Sound intensity level = 10*log10(Sound Intensity/10^-12) to calculate the Sound intensity level, The Sound Intensity Level is the level (a logarithmic quantity) of the intensity of a sound relative to a reference value. Sound intensity level is denoted by β symbol.
