## Sound Energy Formula

The following equation is used to calculate the Sound Energy.

**E = I * A * T**

- Where E is the Sound Energy (Joules)
- I is the sound intensity (W/m^2)
- A is the Area (m^2)
- T is the Time (seconds)

## How to Calculate Sound Energy?

The following example problems outline the steps and information needed to calculate the Sound Energy.

**Example Problem #1**

- First, determine the sound intensity (W/m^2). In this example, the sound intensity (W/m^2) is determined to be 51 .
- Next, determine the Area (m^2). For this problem, the Area (m^2) is measured to be 9 .
- Next, determine the Time (seconds). In this case, the Time (seconds) is found to be 4.
- Finally, calculate the Sound Energy using the formula above:

E = I * A * T

Inserting the values from above and solving the equation yields:

E = 51 * 9 * 4** = 1836 **(Joules)

**Example Problem #2**

Using the same method as above, first, we need to measure or determine the variables required by the equation. For this example problem, these are provided as follows:

sound intensity (W/m^2) = 509

Area (m^2) = 49

Time (seconds) = 3

Enter these given values into the calculator or above yields:

E = 509 * 49 * 3 = 74823** **(Joules)
