### Explanations

Note that it uses the same audio filter for all components of the calculation is the most common and widely used variant is the dB (A).

### Input

In this series fills in the audio data for the respective frequency range before the noise-reducing measure.

### Silencer

This fills in the sound-absorbing acoustic data for the respective frequency range.

### Results

This shows how the audio data is after the sound deadening measures for each frequency.

### Sum

Displays the weighted sum of the input frequencies for resperktive row.

### The decibel (dB)

is a logarithmic measure that indicates a relation to a reference value. Commonly used in sound determinations, but also occur in other areas. The basic unit is actually Bel but used almost exclusively with the prefix deci ie 10.1 Bel.

### dB

Refers to the unfiltered sound also called because the sound which it assumes when you then put the filter on top to mimic the ear.

### dB(A)

A-weighting filter is the most commonly used, and is applicable for normal frequencies and ljustyrkor. A-weighting attenuates the low frequencies and amplifies the medium, A-weighted filter is primarily intended to be used in the measurement of the level sounds

### dB(B)

B-weighted filter is supposed to handle the between loud sounds but these B-weighted filter is used rarely lower.

### dB(C)

C-weighted filter is for the loudest sounds sound filter with a C-weighting is used mainly for sound with strong and low frequencies such as fan noise but is also used for short, sharp beeps mean when the C-weighted filters do not suppress the low frequencies in contrast to the A-weighted filter.
