Hello everyone,
we will have our screed installed next week. Today, the laundry chute was installed. Since the pipe riser is right next to it, there is naturally an air gap around the laundry pipe.
What should be used to fill the gap to achieve the best possible sound insulation? PU foam and then screed around it on top?

Even if it’s not 100 percent soundproof, clothes aren’t falling down there all day, just briefly once in a while....You’re right from a technical perspective. The main goal here is to ensure the system doesn’t transmit sound from other noise sources. It’s problematic if, for example, impact noise is amplified due to insufficient decoupling, or if an unintended multi-room sound system is created as soon as a radio plays somewhere.seat88 schrieb:

Noise from the utility room into the room where you throw the laundry?
That’s what it’s about, not the laundry itself...

Last week, someone here was mainly concerned that the noise in the laundry chute should above all be germ-free.
In principle, this pipe is like a simple telephone, and it is only by preventing sound from passing through that the air column inside becomes truly effective. Transmission through the vibration of the pipe itself is not reliably reduced by plugging its opening or sealing wall penetrations, since fastenings still act as excellent transmitters. What is this really about: the fear that the banging of the spinning washing machine will be transmitted into the sleeping area, and possibly even amplified by the pipe acting as a resonance chamber?
In most cases, this will probably be what could politely be called a luxury problem—any disturbances to residential comfort caused by an unsealed "connecting pipe" will likely be noticed only by very sensitive individuals. The family being unable to sleep because the dryer is humming would more likely be considered a serious issue.

Traum201910 Feb 2020 21:18My concern is more about the noise transmission through the opening around the pipe. I am, of course, fully aware that the pipe itself transmits sound.
As I tried to explain above, the passing sound actually reduces the transmission quality of the air column inside the pipe, and also results in a broader spectrum. This means that this sound does not have a sharply defined peak at any frequency like the one that travels through the pipe (because the pipe has one inner diameter = one resonance frequency = one particularly well-transmitted range within the spectrum, while the surrounding frequencies are more varied but without any specific range that is notably loud). Therefore, my conclusion is that you are dealing here with a philosophical rather than a practical problem, and you can relax without needing to approach the sound with heavy countermeasures.
