Soundproof room - Ceiling attic hatch and AC duct

[morr]

So, a sound eater! I would love to have one of those! (Sorry, it's not nice to laugh at typos but this one was so good!)

What I noticed when I had an acoustician acquaintance visit to check my troublesome ventilation was that he could quite easily say HOW something should be fixed, or at least suggest measures that could help. And he pointed out which of my ideas probably WOULDN'T help in removing the noise. WHAT is making the noise is usually quite easy to find, but finding the right solution is not as obvious and it's easier for someone who is on site. But finding such a person and affording it is not as obvious. People who build studios or hi-fi enthusiasts can sometimes be good at this too.

By the way, this might possibly go under housing adaptation? If it's considered a disability and the renovation necessary. Check with the municipality if so. If you/they can manage.

Sound eaters would be really good to have, yes. :3

Yes, it's the housing adaptation grant I intend to apply for these constructions, actually.
Thanks for the reminder. :3

I have contacted the specialist doctors and such, so the certificates are in progress.
I just hope the municipality doesn't cause any trouble.

Try to get the municipality to approve a consultation with an acoustician as well, maybe?! That way you won't end up building something that might not help...

You might have already checked this, but in some municipalities, the municipality decides who will build the adaptation. It might be good to check with that company as well (and make sure they know what they're doing. I've experienced a bathroom company that claimed to be knowledgeable but still installed the toilet incorrectly, making it unusable with a hygiene chair, which was the purpose of the adaptation...). Good luck!

Okay, consulting is fine with me, and someone else can happily do the actual construction too... Heheh...

How do you know if a company knows what they're doing?
Since I'm not a professional builder, I'm not quite sure what to look for, besides the obvious parts.

Thanks!

In general, not all construction companies have a clue, so you should have a person and company specialized in room acoustics.

Good to know. Thank you~

I doubt that the local authorities know anything about room acoustics (a guy who was responsible for housing adaptation told me that you could hang up curtains to soundproof, and he also claimed that there are no other ways to soundproof...), so I hope they are willing to find someone who really knows.

Curtains to improve the sound environment are great but maybe not for what you need. I think you need to find a sound consultant/acoustic expert yourself. Search for "acoustic expert" + your location and contact those who seem promising. Describe the problem (you can use this thread) and ask if they are familiar with your diagnosis. Request a quote and then contact the housing adaptation department at the municipality again.

What I think will be the hardest to solve is, as mentioned, proper ventilation in the room that doesn't allow sound to pass through. The rest, you've gotten answers here that seem good (but it's always good to check with a professional).
By the way, is it possible to switch rooms so that you avoid the fan on the other side of the wall?

If I'm not mistaken, there was recently a ruling regarding housing adaptation and soundproofing. However, I believe it concerned the opposite, that it was about not disturbing neighbors.
The verdict, if I remember correctly, was that this type of measure is not covered by the housing adaptation law.
I'll see if I can find it when I am TB at work.

Forget it! Mixed it up with LSS 9:9, in the form of a specially adapted residence, which cannot mean soundproofing etc.
For soundproofing of bedrooms, etc., there are administrative court rulings. For example, Stockholm, 200629 case 8367-19

Nice that you found rulings to refer to!

The doctors reached out today and claimed they can't assist with the housing adaptation application at the moment. I have to submit my application anyway.

 

[Toppentuppen]

I'll have to send in my application anyway.

Nope, apparently not. The application must include a certificate from an "Occupational therapist or expert." I didn't expect the specialist doctors to dig their heels in.
