The Intensity and Loudness of Sound Waves Calculator will calculate the:
|The intensity of sound waves when energy of sound and distance from the source are known is W/m2|
|The loudness of sound waves when their intensity is known is dB|
|Intensity of sound wave calculation|
|I = E × v/4π × r3|
I = × /(4 × ) × 3
I = / ×
I = /
|Loudness of sound wave calculation|
|L(dB) = 10 × logE × v/4π × r3 × I0|
L(dB) = 10 × log × /(4 × ) × 3 ×
L(dB) = 10 × log/ × ×
L(dB) = 10 × log/
L(dB) = 10 × log()
L(dB) = 10 ×
|Intensity And Loudness Of Sound Waves Calculator Input Values|
|Energy of sound waves (E) J|
|Speed of sound wave (v) m/s|
|Distance from the source (r) m|
|Archimedes constant (π)|
|Threshold of hearing (I0) W/m2|
Please note that the formula for each calculation along with detailed calculations are available below. As you enter the specific factors of each intensity and loudness of sound waves calculation, the Intensity And Loudness Of Sound Waves Calculator will automatically calculate the results and update the Physics formula elements with each element of the intensity and loudness of sound waves calculation. You can then email or print this intensity and loudness of sound waves calculation as required for later use.
