ᐅ Unfinished ventilation system (mechanical ventilation with heat recovery), noise disturbance when sleeping in the room below?

Hello everyone,
The installation of the controlled residential ventilation system was planned for our attic. This way, the ducts can be better distributed to the rooms below, and we saved space in the utility room.
Our bedrooms are located on the upper floor (master bedroom, walk-in closet, two children’s rooms, and bathroom). The ceiling to the attic is a wooden beam ceiling with OSB boards, which is insulated but naturally does not provide as much soundproofing as a conventional concrete ceiling on the ground floor. The intended location for the unit is directly above the bedroom. The intake opening is planned to face the gable side. On this side, there is also a children’s room.
Now, I am a bit concerned about noise. I’m wondering if the operation noise of the controlled ventilation system might disturb our sleep at night, or if it is usually quiet enough not to be noticed?
Relocating the system to the other gable side would be possible (there is the bathroom and another children’s room on that side), so we would position the ventilation unit directly above the bathroom, hoping that the noise would then not be heard in the second children’s room.
The disadvantage is that the chimney is also located on this gable side, connected to a wood stove. Could it be possible that, depending on weather conditions and chimney draft, the intake opening of the controlled ventilation system might draw in exhaust gases from the chimney?
Has anyone else installed the controlled residential ventilation system in the attic (within the insulated building envelope)?

I’ll call it an intake nozzle since I can’t think of a better term.
So the component doesn’t come from the ventilation system manufacturer but from a separate supplier, and it has an unnecessary grille—am I understanding that correctly?
Does it actually make a difference whether I vent through the gable wall or through the roof at the top? I’m thinking about air temperature, noise levels, intake of dirt, or anything else.
I didn’t mean to question that it’s a good tip; I just wanted to make sure I understand what you meant correctly.
Thanks and best regards.

These facade grilles (air intake vents) are usually purchased by contractors as accessories from wholesale suppliers.
When choosing the location, wind direction and neighboring properties should be considered. After all, you don’t want to disturb others with noise or draw in unpleasant odors from nearby sources (such as the fireplace lighting process). The roof is generally a good choice, but make sure that the outdoor air intake cannot mix with the exhaust air. (Maintain a sufficient distance and take the prevailing wind direction into account.)
