Sound Intensity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sound Intensity = Sound Power/Area
l = W/A
This formula uses 3 Variables

Variables Used

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.
Sound Power - (Measured in Watt) - Sound Power is the rate at which sound energy is emitted, reflected, transmitted or received, per unit of time.
Area - (Measured in Square Meter) - The area is the amount of two-dimensional space taken up by an object.

STEP 1: Convert Input(s) to Base Unit

Sound Power: 16 Watt --> 16 Watt No Conversion Required
Area: 50 Square Meter --> 50 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

l = W/A --> 16/50

Evaluating ... ...

l = 0.32

STEP 3: Convert Result to Output's Unit

0.32 Watt per Square Meter --> No Conversion Required

FINAL ANSWER

0.32 Watt per Square Meter <-- Sound Intensity

< 7 Sound Intensity Calculators

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 Formula

Sound Intensity = Sound Power/Area
l = W/A

What is sound power?

Sound power or acoustic power is the rate at which sound energy is emitted, reflected, transmitted or received, per unit time.

How to Calculate Sound Intensity?

Sound Intensity calculator uses Sound Intensity = Sound Power/Area to calculate the Sound Intensity, The Sound Intensity is defined as the power carried by sound waves per unit area in a direction perpendicular to that area. The SI unit of intensity, which includes sound intensity, is the watt per square meter. Sound Intensity is denoted by l symbol.

How to calculate Sound Intensity using this online calculator? To use this online calculator for Sound Intensity, enter Sound Power (W) & Area (A) and hit the calculate button. Here is how the Sound Intensity calculation can be explained with given input values -> 0.32 = 16/50.

FAQ

What is Sound Intensity?

The Sound Intensity is defined as the power carried by sound waves per unit area in a direction perpendicular to that area. The SI unit of intensity, which includes sound intensity, is the watt per square meter and is represented as l = W/A or Sound Intensity = Sound Power/Area. Sound Power is the rate at which sound energy is emitted, reflected, transmitted or received, per unit of time & The area is the amount of two-dimensional space taken up by an object.

How to calculate Sound Intensity?

The Sound Intensity is defined as the power carried by sound waves per unit area in a direction perpendicular to that area. The SI unit of intensity, which includes sound intensity, is the watt per square meter is calculated using Sound Intensity = Sound Power/Area. To calculate Sound Intensity, you need Sound Power (W) & Area (A). With our tool, you need to enter the respective value for Sound Power & Area and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Sound Intensity?

In this formula, Sound Intensity uses Sound Power & Area. We can use 2 other way(s) to calculate the same, which is/are as follows -

Sound Intensity = ((Sound pressure^2)/(Density of Air*Velocity of sound wave))
Sound Intensity = (10^-12)*10^(Sound intensity level/10)
