Concrete Walls NOT Soundproof AT ALL - Let's Make Them!

  For people in existing houses, I think the most important thing here is to identify the types of sounds, the level, and precisely where they are coming from. Humans are pretty good at ignoring sounds below a thresholds (JNDs) and you can often get close to your "don't care anymore" point with soft furnishings and heavy furniture like bookcases. Also, think about parallel walls and ceilings with tile and concrete (especially coincident ones). You are unwittingly in an echo chamber and might only need a thick rug, a runner with wool or rubber underneath, or a plush headboard to interfere with several dB.  You can buy decorative acoustic wall hangings in Ikea. Place them at nodes.  If it's impact, you will have to figure out what part of the structure is resonating. Hard things like concrete resonate when vibrated. Figure out what causes the sound (chairs sliding, banging) and you might be able to find what the weaknesses are. Chairs aren't on the wall, for example

  <a href="https://www.youtube.com/watch?v=V2MToMPFAvQ&amp;t=189">3:09</a> I think we have different definition of concrete wall. What you have here is concrete blocks wall, not full concrete wall. Those blocks are empty inside with only thin conrete wall. Not to compare with concrete walls with regular rebar support.

  Was in the building sector in Sweden for 8 years, been in concrete houses from the 50s and 60s 90% of my time and most of it is built bad. When someone is over or under you with a big concrete grinding machine you hear if it&apos;s built good enough. If made correct it&apos;s superb.

  This might work for airborne noise, but what about impact noise?<br>For me, that&apos;s a MUCH bigger issue!

  Concrete is over 3 times denser than drywall, plywood, mdf or osb. <br>But a single wall of cinder blocks is not going to do magic.

  I&apos;d recommend put your reading material near the camera lol<br>Also saying that 1 layer of air gap is sufficient isn&apos;t always true when trying to block out a low frequency bass sound

  I&apos;m buying a property in Mexico during the construction phase. The developer said they can modify anything at cost. What&apos;s the best solution? The whole apartment is polished concrete. Floors walls etc. Cinder block on the dividing walls and slab ceiling. I&apos;m concerned about the cinderblocks partioning each apartment.
