Sound proofing and wall batons

with 3 comments

I live in a semi-detached house and therefore have to be considerate to our neighbours when it comes down to making noise, so adding more sound-proofing to to the dividing wall ahead of a AV install is a bit of a no brainer.

After doing a bit of google searching I found a wall-mounted product that should decrease noise by about 50%. Padding out the dividing wall with another layer of plaster board with about 50mm of acoustic wool attached however creates some challenges when it comes down to mounting a TV to the wall (what the hell do you screw the brackets into?).

So before adding the sound proofing to the wall, I added a couple of batons in the correct place for the LCD wall-mount and (hopefully) the center speaker. These should provide a good backing to screw a mount into.

I also ran some trunking over the wall to manage the hidden cables.

I have run power, a couple of HDMI, a SCART, and a VGA cable through the conduits (note that power takes it’s own path to minimise interference with AV signals. The challenge after adding these cable runs and batons is to make sure the sound insulation will be able to snugly attach to the *plaster* of the original wall. The only way to make this happen is to spend a long time with a craft knife and a ruler.

Believe it or not, cutting the above piece to size, channelling out cable runs to the minimum required depth, and attaching it to the wall took a couple of hours. And yes, I know that cutting into the insulation will decrease it’s effectiveness but It’s better than nothing and allows me to hide a lot of cable.

  1. Could you do me the imense favour, I am a little new to linux but am trying to learn about Snort and so far I’ve managed to install Snort.tar.gz no problem, so then I went one better and installed Snortsp beta 3.0 however I have run into one snag, when I type snortsp I get the following error.

    snortsp: error while loading shared libraries: cannot open shared object file: No such file or directory

    I did a whereis and located the missing library in;


    How do I tell snortsp where to find it?

  3. Our neighbours decided to use additional acoustic insulation ad soundproofing when they did up their house.

    They got some Floating Flooring as well as wall batons.

    I thinks it’ made a big difference – it also measn that we don’t hear the washing machine as much either!!!
