ᐅ Sewer Pipe Noise Passing Through the Room?

In our single-family home, a wastewater pipe from the bathroom above (shower room with WC) is planned to run through the living area, enclosed with 11cm (4.3 inches) bricks. My question is whether this will be noticeably noisy. Until now, I have lived in the attic and am not familiar with this. If noise is an issue, are there soundproofing options? We do not want to change the floor plan.

Thank you for your answers.

Yes, you will hear it. That’s why it is usually planned accordingly to avoid this exact situation, because it’s not pleasant when guests are sitting in the living area and hear your toilet flushing 😉 Redesigning is not an option... well, then it just is what it is.

Thanks for your answers.

The question would be whether you could soundproof this by enclosing it with Silentboard drywall panels from Knauf or similar products. The sound insulation values are quite good when used as a drywall partition.

There is an improvement, but you cannot make it completely inaudible. It will always remain clearly noticeable. The only effective solution is a different cable routing or, as is usually done, a practical floor plan that takes such issues into account.

There are also "sound-optimized" wastewater pipes available, for example from Geberit. Maybe you can get a bit more noise reduction that way.

But it will probably be as @Tego12 says – it likely won’t be completely silent.

My question is whether the noise level will be significantly disturbing. I currently live in the attic and have no experience with something like this. If yes, are there any options for soundproofing? We do not want to change the floor plan.
Thanks for your answers.

Assuming proper insulation behind the brickwork, there should be almost no noise. I had a similar situation behind drywall once – it was only noticeable when the room was completely silent.
