ᐅ Soundproof transfer air devices for wall installation (controlled residential ventilation)

Hello.
We are currently considering options to avoid cutting down doors (to maintain sound insulation). We are already familiar with the usual alternatives, such as frame ventilation, U-seals on the door, and so on. Now, we are interested in the "professional" solution of soundproof transfer elements (through-wall grilles) for wall installation.
Has anyone installed such elements, and do they really improve sound insulation?
Perhaps someone can also recommend a manufacturer you are satisfied with. I have found the following companies but do not personally know any of them...
·Durrer
·Kiefer
·Lindab
·LTG
·Schako
·Swegon
·Systemair
·Westaflex

It would be simpler to have one supply and exhaust vent per room where increased sound insulation is required. That way, you avoid a lot of problems.
Isn't that the same as what I mean? Those are also installed in the wall, right? What is the advantage of the supply vent you mentioned?

No, it is not the same. Because with supply and exhaust air in the same room, there is no need for air transfer openings. In other words, the room can then be sealed off completely if desired.

I agree with that. When properly planned, a maximum of 15-20m3 (cubic meters) will flow through. This passes under any standard-compliant door gap. Completely without frame modifications or other elements.

I understand. As far as I know, your solution would require an enormous extra effort in terms of ductwork, or am I mistaken? Exhaust air goes outside, of course. The supply air in your solution with the supply air vents would mean that a separate supply air duct runs into every room. I think this is certainly the best solution acoustically, but the huge extra effort and all the additional supply air ducts seem a bit excessive to me. I hope I’ve understood you correctly...

I have also been considering this issue; the effort required for supply and exhaust air in each room is quite significant.

I will take a closer look at drop seals.

We have no experience with transfer grills; a friend looked into it more closely, but as far as I know, they haven’t been installed either.

For the utility room, we have a soundproof door with a drop-down seal (with transfer function).
