A powerful motor has a greater extraction capacity, but also produces correspondingly more noise. You can reduce the noise by reducing the engine speed. It also reduces the air volume, but the lowest rise is good for most.
Air noise and duct noise
Air in motion causes noise. Just as when the wind rushes, sound is produced when it encounters an obstacle. The straighter - with as few bends and bends as possible - you can position your exhaust and the larger the channels the air is transported through, the less noise it will make.
