ᐅ Low Sound Insulation in a Solid Construction House – What Could Be the Cause?

Hello everyone,
We have been living in a solid brick house for just under six months and are very dissatisfied with the sound insulation.
The exterior walls are made of 36.5cm (14.4 inches) thick masonry, and the interior walls are 24cm (9.4 inches) thick Wienerberger Poroton bricks. The windows are triple-glazed, and the interior doors are hollow-core.
Normally, you would expect to hear very little noise from outside while inside the house. However, sometimes it feels as if all the windows are open because you can clearly hear people walking by the house. The closing of car doors and passing vehicles (in a 30km/h (18.6 mph) zone) is also very annoying.
The noise situation inside the house is by no means better. Our bedroom is located right next to the children's room. At normal speaking volume, it is impossible to have a conversation in the bedroom, and if the TV is on, the volume has to be very low; otherwise, our child wakes up.
When the washing machine or dryer is running in the basement, the noise can also be heard all the way to the bedroom, even though the rooms are on different floors and separated by two doors.
Do you have any idea why our sound insulation is so poor? Previously, we lived in a rental apartment and had significantly better soundproofing than we do now.
Thank you very much in advance for your help.

I guess the reason you can hear everything so clearly outside through the window ventilation slots is because of that... I have a friend who closed hers because it was so loud. And if you built with bricks, you probably don’t rely on mechanical ventilation...
What was different about the rental apartment — the construction method, size, floor coverings?
Unfortunately, I also find that modern houses with wooden floors and plastered walls often tend to have an echo...

Hello,
we will also be building with 36.5cm Poroton blocks and plan to install trickle vents in the window rebate. However, I will be installing a decentralized unit with heat recovery in the living/dining area and open kitchen space. I hope to use the trickle vents at least in these rooms as a backup if noise does actually become an issue.
Since we are still before the material selection and technical building consultation phase, it would be great if you could give me some advice on what to watch out for to avoid noise problems here.

garfunkel23 Jun 2019 12:10If you value soundproofing, avoid trickle vents in window sashes. A window with a trickle vent is never fully sealed, so I wouldn’t recommend it.
I don’t know any house with truly good sound insulation that has trickle vents or decentralized ventilation systems.
