Sound Intensity Solution

Follow our step by step solution on how to calculate Sound Intensity?

FIRST Step Consider the formula

I = \frac{W}{A}

Next Step Substitute values of Variables

∴

I = \frac{1.4E-9W}{14m²}

Next Step Prepare to Evaluate

∴

I = \frac{1.4E-9}{14}

LAST Step Evaluate

∴

I = 1E-10W/m²

How to Evaluate Sound Intensity?

Sound Intensity evaluator uses Sound Intensity Level = Sound Power/Area for Sound Intensity to evaluate 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 evaluate Sound Intensity using this online evaluator? To use this online evaluator for Sound Intensity, enter Sound Power (W) & Area for Sound Intensity (A) and hit the calculate button.

FAQs on Sound Intensity

What is the formula to find Sound Intensity?

The formula of Sound Intensity is expressed as Sound Intensity Level = Sound Power/Area for Sound Intensity. Here is an example- 1.8E-10 = 1.4E-09/14.

How to calculate Sound Intensity?

With Sound Power (W) & Area for Sound Intensity (A) we can find Sound Intensity using the formula - Sound Intensity Level = Sound Power/Area for Sound Intensity.

What are the other ways to Calculate Sound Intensity Level?

Here are the different ways to Calculate Sound Intensity Level-

Sound Intensity Level=((Pressure RMS^2)/(Density of Air*Velocity of Sound Wave))
Sound Intensity Level=(10^-12)*10^(Sound Level in Decibels/10)

Can the Sound Intensity be negative?

No, the Sound Intensity, measured in Intensity cannot be negative.

Which unit is used to measure Sound Intensity?

Sound Intensity is usually measured using the Watt per Square Meter[W/m²] for Intensity. Watt per Square Centimeter[W/m²], Watt per Square Millimeter[W/m²], Kilowatt per Square Meter[W/m²] are the few other units in which Sound Intensity can be measured.
