Spring-Loaded Screw Turns Drywall Into Sound-Absorbing Panels


This looks promising for a 9db reduction in sound escape in homes.

Apparently the spring loaded screw acts as a dampener of sound vibrations that hit a regular dry-wall.In principle, the screw is split in the middle with a spring placed inside. The screw tip goes into the wooden joist, the head holds the plasterboard in place and in between a thin resilient mechanical coupling that prevents the sound waves from advancing is formed.

They have patents and are looking for mass production.https://www.akoustos.se/

I’d certainly consider it for renovations and new builds.

When room interact with recorded sound, the recorded sound is distorted. Period.

The BEST listening is in a dead room. Your statement that rooms should not be deadened is promoting that distortion. Period. It interferes with imaging, can upset the soundstage and changes musical instrument harmonics. Period.

Distortion in room is ABSOLUTELY something you want to be NULL. We must minimize distortion / reflections from the walls. Those quite simply interfere with the reproduction of the recorded signal. There will be reflected sound on that recording. We cannot add to that distortion by using a live rom.

There is nothing to say in rebuttal. If the goal is undistorted music exactly how it was recorded, then a dead listening room (or headphones that do exactly the same thing as a dead room) is the only way to go. Anything else is distorted.

DEAD ROOMS do not have to look like an anechoic chamber. They can be nicely decorated and pleasant.

Yes that what i also said but I tried to say it more simple: when someone talk to you in a room then you have reflection or like you say distortion. That is the norm and what we are used to when it is normal. So yes no need for periods.πŸ˜‰

I am not English speaking and it is not my first language. But here is the confusion. What you call a dead room and want to be NULL.
That is ONLY obtained in a an anechoic chamber.
EVERYTHING else is NOT as you write a dead room. It is like you write:
We must minimize distortion / reflections from the walls.
It is like you write MINIMIZE and in other words something is still left (usually >20% is still bouncing around in the room variation by frequencies)

So that what YOU call dead room I call it more or less lively. And my bar is much higher for what is a dead room is a anechoic chamber nothing else is a completely dead room.

What you call dead room I call that it is just a TREATED ROOM. It is FAR from a dead room in my opinion and also if we measure. So it is easily proved.

So I hope the issue is that we just use different vocabulary nothing else. πŸ€”πŸ₯³πŸŽΆπŸŽΆπŸ’–

Mho...I don't think any inspector worth his creds would sign off on those sprung screws in new construction...πŸ˜’Β  Flame spread could be one call; unsecured attachment another...
The spring looks to be the same diameter as the 'exposed finished face collar' which would allow the panels to loosen over time. Surprising any trade with something they're not familiar with tends to get the worker(s) pulled and change orders made.
And the 'mud & tape' crew would hate everything about it.Β  The seam tape mud would tend to crack when finish sanding them...
...not to mention having to potentially mud the entire wall to cover all the exposed heads of the screws, which can add to their time/bid figures going into the round file and profit out the window.
Then the painters come in to coat the room....and attempt to make the install look proper.Β  If any of the previous hits their ears, they'll spray the space and call it a day.

Better: a wall constructed to 'unlock' exterior from interior, with wider footings and upper plates employing offset studs of a narrower width.
Doubles the studs, but works not only for sounds, but for your R values as well...fill the void with rock wool and close up per Typical.

In a reno, spend $ on room treatments...better bang/buck ratio.

Unless you're already an architect with access to a acoustician...then, we're talking commercial, and none of the above will apply.

Just be firmly seated when the bids come in.... ;)

Have an exciting, fun-stuffed weak, J
