Enter the sound intensity (W/m^2), the Area (m^2), and the Time (seconds) into the calculator to determine the Sound Energy. 

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

  1. First, determine the sound intensity (W/m^2). In this example, the sound intensity (W/m^2) is determined to be 51 .
  2. Next, determine the Area (m^2). For this problem, the Area (m^2) is measured to be 9 .
  3. Next, determine the Time (seconds). In this case, the Time (seconds) is found to be 4.
  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)
