ᐅ After reviewing the development plan, are noise protection measures necessary?

Hello,
I have completed all the preliminary planning and sent all the documents to the builder.
The builder has determined that, according to the development plan, specific soundproofing measures are required for the plot.
The house upgrade includes a decentralized ventilation system, special soundproof windows, soundproof insulation for the roller shutter boxes, and a noise protection expert.
Of course, with additional costs.
However, I am not very satisfied with the decentralized ventilation system and believe a central ventilation system would be better.
What is your opinion?

There are often a few more issues in show homes:
- Covers damaged or not properly secured.
- System set too high ("party mode")
- No proper central mechanical ventilation with heat recovery, but often an air-to-air "heat pump" instead (based purely on my experience, these air-to-air units were consistently noisier, even in summer operation, than a regular central mechanical ventilation system with heat recovery).
- Incorrectly sized ventilation system (this can also happen during planning; too much power at the outlet = noise). Now that I think about it, you’re right.
In the show home exhibition park, it felt like every second system I saw was showing an error message. One system was even rattling continuously.

Is there any useful information about it? Which system exactly? What do you mean by "useful"?
Zehnder works and does what it is supposed to do. Is that sufficient?

Not just one. That’s half a dozen units. Each requires a 150–180 mm (6–7 inch) duct inside the wall. You don’t want that. It definitely gets really loud inside the house. Blah blah blah. Honestly, on setting 1, even first-time visitors don’t notice it.
With your idea of “really loud,” 85% of people wouldn’t be able to sleep. Every passing car with closed windows is louder than a decentralized ventilation on level 1.
The advantage is that I don’t have dozens of meters of ventilation ducting inside walls or ceilings that I’ll never be able to access again.
Better to have that than no ventilation at all for cost reasons.

The additional cost for switching from a decentralized controlled residential ventilation system to a centralized controlled residential ventilation system is reasonable, and I will most likely order the latter.
It is a system from Zehnder. I already mentioned that a general contractor’s preference for decentralized systems can indicate a lack of expertise, and I named several prefabricated house consultants (Beuler and Freyermuth, nationwide as far as I know, Zink probably not covering all of Bavaria).
