Enter the path length (m) and the reference integer into the Calculator. The calculator will evaluate the Destructive Frequency.

## Destructive Frequency Formula

DF = L / (n+1/2)

Variables:

- DF is the Destructive Frequency (hz)
- L is the path length (m)
- n is the reference integer

To calculate Destructive Frequency, divide the path length by the sum of the reference integer plus .5.

## How to Calculate Destructive Frequency?

The following steps outline how to calculate the Destructive Frequency.

- First, determine the path length (m).
- Next, determine the reference integer.
- Next, gather the formula from above = DF = L / (n+1/2).
- Finally, calculate the Destructive Frequency.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

path length (m) = 3

reference integer = 8
