# Decibel Calculator

The dB calculator tool is really a great tool. If you don’t know how to calculate dB then you can use this tool to calculate dB.

#### Input Data

$$Ref.\ pressure = 0.00002\ Pa$$ $$Pressure = 10\ Pa$$

#### Solution

$$Sound\ pressure\ level\ (SPL)= 113.9794\ dB$$

#### Formula

$$Sound\ pressure\ level\ (SPL) = 20log_{10} \frac{P}{Pref}$$ where:
SPL is the sound pressure level in dB
P is the sound wave pressure, measured in pascals; and
Pref is the reference value of sound pressure. Typically, it is assumed to be equal to 0.00002 Pa.

## How to use dB calculators?

The dB calculator tool is really a great tool. If you don’t know how to calculate dB then you can use this tool to calculate dB. This tool will help you calculate your dB with a second.

There is so many people in this world who want to have an calculator which make their life easy. This calculator is really a great tool for them and this can help them a lot and this can help lot of people.

This tool is really a quick tool. It can be used in all over the world. Its really simple to use and even there is no any registration and not any one have to provide the email.

## What is dB Calculators?

At the point when we hear a noisy commotion, we experience terrible emotions. It is a direct result of the pressing factor of a sound wave. Despite the fact that this pressing factor can be estimated in Pascals, similar to pneumatic force, it is more down to earth to utilize decibels - a logarithmic unit. The sound pressing factor level, or SPL, is just the proportion of sound pressing factor concerning the human hearing limit.

SPL = 20log(P/Pref)

where:

SPL is the sound pressing factor level in dB;

P is the sound wave pressure, estimated in pascals; and

Pref is the reference estimation of sound pressing factor. Commonly, it is thought to be equivalent to 0.00002 Pa.

As you likely saw, the SPL increments logarithmic-ally. Likewise, it is a relative measure, while the customary sound wave pressure is a flat out proportion of uproar.
