Decibel Distance Calculator

Formula

The formula to calculate the Decibel Distance (D2) is:

$\text{D2} = \frac{\text{D1}}{\sqrt{\frac{\text{I2}}{\text{I1}}}}$

Where:

A decibel distance is a measure of distance that a certain decibel level is reached given an initial distance and sound level from the sound source.

Let's assume the following values:

Using the formula:

$\text{D2} = \frac{10}{\sqrt{\frac{50}{100}}} = 14.14 \text{ units}$

The Distance at point 2 (D2) is 14.14 units.
