Air sound emission

Professional Definition
> Airborne sound emission is the radiation of sound by a specific source during its operation.

Described by the level of acoustic power ( LWL_WLW​

), it theoretically does not depend on the room.

## Acoustics in Simple Words
Think of a light bulb. Emission is its power (e.g., 100W). It doesn’t matter whether you screw it into the bathroom or into a warehouse – the bulb “produces” the same amount of light. How bright the room seems is the immission.

## Summary
A parameter necessary for creating acoustic maps and comparing the loudness of household appliances.
