Intensity of Sound Solution

STEP 0: Pre-Calculation Summary

Formula Used

Sound Intensity = Power/Normal Area
I_s = P/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.
Power - (Measured in Watt) - Power is the amount of energy liberated per second in a device.
Normal Area - (Measured in Square Meter) - Normal Area is the area in the direction of propagation.

STEP 1: Convert Input(s) to Base Unit

Power: 900 Watt --> 900 Watt No Conversion Required
Normal Area: 45 Square Meter --> 45 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I_s = P/A --> 900/45

Evaluating ... ...

I_s = 20

STEP 3: Convert Result to Output's Unit

20 Watt per Square Meter --> No Conversion Required

FINAL ANSWER

20 Watt per Square Meter <-- Sound Intensity

Length of Open Organ Pipe

Go Length of Organ Pipe = Number of Nodes/2*Velocity of Wave/Wave Frequency

Loudness

Go Loudness = 10*log10(Sound Intensity/Reference Intensity)

Velocity of Sound in Liquid

Go Velocity of Wave = sqrt(Bulk Modulus/Density)

Velocity of Sound in Solids

Go Velocity of Wave = sqrt(Elasticity/Density)

Mass per Unit Length of String

Go Mass per Unit Length = Tension of String/(Velocity of Wave^2)

Time Period given Velocity

Go Time Period of Progressive Wave = Wavelength/Velocity of Wave

Time Period using Angular Frequency

Go Time Period of Progressive Wave = (2*pi)/Angular Frequency

Tension in String

Go Tension of String = Velocity of Wave^2*Mass per Unit Length

Length of Closed Organ Pipe

Go Length of Organ Pipe = (2*Number of Nodes+1)*Wavelength/4

Wave Number using Angular Frequency

Go Wave Number = Angular Frequency/Velocity of Wave

Frequency of Wavelength using Velocity

Go Wave Frequency = Velocity of Wave/Wavelength

Frequency of Progressive Wave

Go Wave Frequency = Angular Frequency/(2*pi)

Intensity of Sound

Go Sound Intensity = Power/Normal Area

Wave Number

Go Wave Number = (2*pi)/Wavelength

Frequency of Wave using Time Period

Go Wave Frequency = 1/Time Period of Progressive Wave

Time Period using Frequency

Go Time Period of Progressive Wave = 1/Wave Frequency

Intensity of Sound Formula

Sound Intensity = Power/Normal Area
I_s = P/A

What is power of sound?

The sound energy consumed per unit of time is known as power. SI Unit of power of sound is watt. In older works, power is sometimes called activity. Power is a scalar quantity.

How to Calculate Intensity of Sound?

Intensity of Sound calculator uses Sound Intensity = Power/Normal Area to calculate the Sound Intensity, The intensity of Sound is amount of energy flowing per unit time through a unit area that is perpendicular to the direction in which the sound waves are travelling. Sound Intensity is denoted by I_s symbol.

How to calculate Intensity of Sound using this online calculator? To use this online calculator for Intensity of Sound, enter Power (P) & Normal Area (A) and hit the calculate button. Here is how the Intensity of Sound calculation can be explained with given input values -> 3.777778 = 900/45.

FAQ

What is Intensity of Sound?

The intensity of Sound is amount of energy flowing per unit time through a unit area that is perpendicular to the direction in which the sound waves are travelling and is represented as I_s = P/A or Sound Intensity = Power/Normal Area. Power is the amount of energy liberated per second in a device & Normal Area is the area in the direction of propagation.

How to calculate Intensity of Sound?

The intensity of Sound is amount of energy flowing per unit time through a unit area that is perpendicular to the direction in which the sound waves are travelling is calculated using Sound Intensity = Power/Normal Area. To calculate Intensity of Sound, you need Power (P) & Normal Area (A). With our tool, you need to enter the respective value for Power & Normal Area and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
