Elimination. Elimination is a process that eradicates the noise source it is the most effective way to prevent risks to workers and should always be considered when introducing a new work process, selecting new work equipment and designing the layout of the workstations.

What causes aircraft noise?

If we’re talking basic physics, the noise from a plane is caused by two things: by air going over its fuselage and wings (or ‘airframe’) and by the engines. Engine noise is created by the sound from the moving parts of the engine, and also by the air being expelled at high speed once it has passed through the engine.
