Sound Intensity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sound Intensity Level = Sound Power/Area for Sound Intensity
I = W/A
This formula uses 3 Variables

Variables Used

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).
Sound Power - (Measured in Watt) - The Sound Power refers to the rate at which sound energy is emitted, reflected, transmitted or received, per unit of time.
Area for Sound Intensity - (Measured in Square Meter) - The Area for Sound Intensity refers to the surface over which sound power is distributed, determining how much sound energy passes through per unit area, typically in m².

STEP 1: Convert Input(s) to Base Unit

Sound Power: 1.4E-09 Watt --> 1.4E-09 Watt No Conversion Required
Area for Sound Intensity: 14 Square Meter --> 14 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I = W/A --> 1.4E-09/14

Evaluating ... ...

I = 1E-10

STEP 3: Convert Result to Output's Unit

1E-10 Watt per Square Meter --> No Conversion Required

FINAL ANSWER

1E-10 Watt per Square Meter <-- Sound Intensity Level

< 7 Sound Intensity Calculators

Sound Intensity with respect to Sound Pressure

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

Density of Air given Sound Intensity

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

Sound Intensity Level

Go Sound Level in Decibels = 10*log10(Sound Intensity Level/10^-12)

Power of Sound Wave given Sound Intensity

Go Sound Power = Sound Intensity Level*Area for Sound Intensity

Unit Area given Sound Intensity

Go Area for Sound Intensity = Sound Power/Sound Intensity Level

Sound Intensity

Go Sound Intensity Level = Sound Power/Area for Sound Intensity

Sound Intensity using Sound Intensity Level

Go Sound Intensity Level = (10^-12)*10^(Sound Level in Decibels/10)

Sound Intensity Formula

Sound Intensity Level = Sound Power/Area for Sound Intensity
I = 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 Level = Sound Power/Area for Sound Intensity to calculate the Sound Intensity Level, The Sound Intensity formula 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 Level is denoted by I symbol.

How to calculate Sound Intensity using this online calculator? To use this online calculator for Sound Intensity, enter Sound Power (W) & Area for Sound Intensity (A) and hit the calculate button. Here is how the Sound Intensity calculation can be explained with given input values -> 1.8E-10 = 1.4E-09/14.

FAQ

What is Sound Intensity?

The Sound Intensity formula 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 I = W/A or Sound Intensity Level = Sound Power/Area for Sound Intensity. The Sound Power refers to the rate at which sound energy is emitted, reflected, transmitted or received, per unit of time & The Area for Sound Intensity refers to the surface over which sound power is distributed, determining how much sound energy passes through per unit area, typically in m².

How to calculate Sound Intensity?

The Sound Intensity formula 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 Level = Sound Power/Area for Sound Intensity. To calculate Sound Intensity, you need Sound Power (W) & Area for Sound Intensity (A). With our tool, you need to enter the respective value for Sound Power & Area for Sound Intensity 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 Level?
