ᐅ Issues with Impact Sound Insulation in a New Condominium

Good day

We have been living in a new condominium for six months. It was traditionally built with concrete ceilings, shuttered masonry with external insulation.
We wonder if it is normal to hear the upstairs neighbors walking around, water running, and the washing machine vibrating, etc. Shouldn’t this be avoidable in a building from 2012 with today’s standards?

According to the plans, the construction is as follows: 24 cm (9.5 inches) concrete ceiling, 4 cm (1.5 inches) insulation (of which 2 cm (0.75 inches) is impact sound insulation), 7 cm (2.75 inches) anhydrite screed, and finished with tiles or parquet.

The plans also show that a “Swedish cut” was made everywhere at ceiling/wall junctions, and the walls rest on BASYDIL LDS sound insulation supports.

We are now almost ready to carry out a noise measurement because the general contractor and the architect deny any issues. They claim it was built according to standard 181.

Can anyone share similar experiences or possibly recommend an acoustician in the Solothurn area?

Thank you very much

Hi Wilma 66,

You are responsible for providing evidence of this noise level. Values alone won’t help here. Hire an expert who can take precise measurements, and with those results, you can then confront the architect.

Good luck

I completely agree. It’s not very effective to try to confront the landlord using cheap devices you bought yourself, because they will want to see measurements done by a qualified expert. It’s also possible they will hire one themselves to prove that the noise is not that bad.

It is quite frustrating when all these noises can be heard. Only experts can really help in such cases, and often both parties arrange for this. I know this from experience with an older apartment.

Thank you for all the replies and advice.
In the meantime, we have had a ceiling measurement conducted. The result is just within the standard. However, this standard only applies to sounds above 100 hertz, and our problem is with the low, deep tones below 100 hertz, which cannot be measured precisely and are therefore not covered by the new standard. Our acoustician believes that the issue is not caused by the ceiling but by the plumbing installation shafts, as we hear the most noise near these shafts. The problem is that this cannot be measured, and it is extremely difficult to determine the exact source of the noise. So, despite the measurement, we are still at square one, and the architect remains unwilling to compromise. By the way, in his view, it is normal to hear people walking on the ground floor when living in the attic.
Now we are left with only two options: pursue legal action or sell the property again.

Hi Bern 66,

That’s really unfortunate, but I think legal action won’t help if these measurements don’t exist. So the only option left is to sell. It’s really a pity.

Best regards
