It always bothered me when someone on America's Funniest Home Videos leaned into a wall (or, ran into it, gently), making a giant hole in it.

- vlozko 5y agoVideos where you see that happening is usually because the drywall was built on studs spacing more than 16" on center. 16" on center is pretty universal and it takes a significantly larger amount of directed force to create such holes.
- lotsofpulp 5y agoWhy? I cannot think of a reason to invest in solid walls that cannot be broken unless you are living in a war zone.
- gambiting 5y agoSound insulation? My mum has a house that's literally built from concrete, and it's impossible to hear anything from one room to another, it's amazing.
- lotsofpulp 5y agoYou can get the same by using quality drywall and insulation and proper air gaps. The minimum code built house will not get you that, but it is easily achievable with stick built. Concrete and steel are still superior of course, and I opt for those in commercial construction. But I have never seen a need for concrete and/or steel in suburban home construction just for noise.
- geoduck14 5y agoBy the way, sound travels better through solids (like concrete) than air.
- gambiting 5y agoI mean......that's true but only if the emitter is attached to the solid, and also only if you measure the transferrence in the solid itself, the solid to air transmission after is extremely poor. Otherwise you'd be telling me that if I suddenly put a concrete wall between us I should hear you better, not worse, right? /s
- geoduck14 5y ago>the solid to air transmission after is extremely poor. >Otherwise you'd be telling me that if I suddenly put a concrete wall between us I should hear you better, not worse, right? /s What if I put 2 sheets of dry wall with an air core in between us? Are you telling me that would give better sound transmission than a solid concrete wall?
- gambiting 5y agoNo, but it's not the air that's deadening - it's the drywall, because just like with concrete, you need to transfer the energy of the sound from the air into the drywall, then air, then drywall, then air again. It's the change between mediums that provides insulation here, in addition to the vibration damping properties of drywall. In fact if you already have concrete walls and want to add sound insulation in your house, the easiest solution and most common solution is to cover them in drywall.
- geoduck14 5y agoSo can we agree, houses built with 2 layers of dry wall and an air core will have more sound deadening than a house built with concrete walls? And that the original posters tale of "superior sound insulation" in a house with concrete walls is likely due to factors other than the concrete walls?
- gambiting 5y agoAll I said was that my mum has a house made entirely of concrete and the noise insulation in that house is insane, you can't hear a single thing from room to room. I'm not a structural engineer however and I have no idea why that is.
- refurb 5y agoI lived in a concrete building and sound travels more than in a wood framed house.
