Enter the sound intensity (W/m^2) into the calculator to determine the sound intensity in decibels.

## Decibel Formula

The following formula is used to calculate the total number of decibels from the sound intensity level.

B = 10 * log ( I / I_{0} )

- Where B is the sound intensity decibels
- I is the sound intensity (W/m^2)
- I
_{0}is the reference sound intensity (equal to 10^{-12}W/m^2 for ambient noise)

## Decibel Definition

A decibel is a unit of measure that defines the intensity of a sound pressure wave.

## Decibel Example

Calculating decibels is typically a process of converting a sound intensity in one unit to another. This can be seen through the formula above that converts W/m^2 into decibels. Since decibels are a measure of the difference of sound pressures, a reference sound pressure must be given.

## FAQ

**What is a decibel?**

A decibel is a unit of measure of the intensity of sound. It’s also a measure of the intensity of power of an electrical signal.

**What is a safe decibel level?**

The human ear can safely endure levels of less than 80 dBA. Any louder and extended exposure will likely lead to ear damage.
