Interior walls sound - door gap

[Ulf1]

Hello
We are building a new house and are considering the best solution for interior walls regarding sound without making them too wide. One thing I'm thinking about is that there are special connection rails with rubber strips against the floor that seal well.. but then there's a gap for ventilation under the door and the door itself is thin compared to the wall. Is it really worthwhile to focus on the walls when the doors are the weak point??

If you have a gap under the door, you will get noise even if you have insulated walls. Why do you have a gap under the door when it's a new house?
To get quiet interior walls, there are some threads on the forum if I remember correctly, just insulation is usually enough, but then there are different panels specifically for sound.

sure, solutions can be done that way. but eventually you will have wear where the door goes.
otherwise, consider one that goes down when the door is closed.
also, you have thresholds on/in the door opening.

preferably invest in slightly more expensive doors that have a better sound classification if it is so important.

We have FTX ventilation. What other simple alternatives are there to reduce noise?

This problem is probably common to most prefabricated houses. We build using lösvirke and can hopefully create a better solution ..

When looking at solutions for the walls online, the gypsum should be sealed at the corners and against the floor, etc., but then the doors leak like a sieve

depends entirely on what door you have. and you can order whatever doors you want.

Do you have tips for a quiet interior door with ventilation?

Do you have any tips for a quiet interior door with ventilation?

depends entirely on what price you want to pay. completely quiet you won't get anyway

 

[Ulf1]

That's right. Considering a silent door without a gap at the bottom and installing overhead air vents with sound dampers. Do you have any experience with this solution?

As I said, as long as there is a gap, it will be heard...

What is the room/requirement?

 

[Ulf1]

All rooms except the laundry basement, requirement: There is no decibel requirement but want to find a good solution that eliminates sound leakage in the door gap. The walls consist of 45 studs that overlap, 70 insulation OSB and gypsum boards.

Search for EI30/35DB

Thanks - with doors at 35Db, it seems an over-air vent is needed.

Isn't it overkill to use double gypsum, seal gaps in the walls, cross braces, insulation, rubber strips against the floor and ceiling, etc., when the door is still the weak point? A regular interior door isn't exactly good for sound, 30mm thick with a gap of 5-10mm at the bottom...
