Soundproofing Help If Needed

[XANTECH]

Hi every one this is my first posting and did not know where to post this, so here goes. I work for a company who do a lot of custom installations, multi room video audio, lighting control, and over the last 3 years a lot more soundproofing of clients properties. If any one out there wants any advice or guidance on either mounting a flat panel tv to a wall or how to get cables hidden, or soundproofing there house just email me.

That does not sound like an advert to me , so I will just ask

Whats the best way to achieve compliance with Part E in a multi-occupancy four storey property, of predominantly timber framed construction?

Hi woody,
thanks for your question, we are not a building company, we only specialise in installation of av systems, and more recently soundproofing peoples properties. From what I am aware of, Part E lays down that walls between dwellings must be capable of reducing the passage of sound through the air. Now even though Part E is being achieved the overall db rating that is allowed is around the 54 - 60db range. Now these figures are very good, but what we have found is that with the increased use of home cinema systems then these figures are to low. Everytime we referance of a home cinema system we weigh the meter at c and look for a referance of 75db. This may not seem to much higher but in a fast paced movie the db range can hit a figure as high as 120db. The original 75db figure is purely the referance to work from and not the true output that can be achieved from any system. With sound ingress being a problem the reason for the posting is to offer advice if required by any one, also advice with regards to the installation of plasmas or lcds.

120db!!! that's the same as a plane taking off, and is beyond the threshhold of pain!

Question:

How to hide cables ? I recently decorated a room then the wife decided to mount a 42" lcd ( that sounds dirty doesn't it) maybe i should re fraise that

Hanging wasn't a problem but there was no way i was going to hack off the plaster and new wall paper. Is there a way to "disguise" the cables rather than totaly hide them ?

Cheers

square plastic conduit, or some camo tape from the army surplus shop.
Alternatively fork out for the new 'predator' range of cabling, they sneak up on ya!

Yes you are right, 120db is the equivalent of a Boeing 747 flying above your house, movies are mastered so that the referance volume level is 75db, when people are speaking on the display then you should not have to raise your voice to be heard, however if a bomb explodes on screen then the systems will output up to 120db and in certain circumstances slightly more. With regards to the question about hiding the cable, then if you have a stud wall or dabbed wall then you may be able to feed the cables between the voids, alternaively there are cable covers which are available to cover the cables, they are slightly more attractive then the normal conduit.

We have been asked by a customer to improve the sound insulation of there party walls. After searching the web for suitable options we went for some panels call M20 Panel Insualtion.
It is supposed to be better than Isowooll etc, and you loose less room space.
Do you have any opinions on these panels or other products?
Cheers

If I were you have a word with your customer and explain that it would be better to loose some room, with regards to sound reduction methods this is how we normally soundproof any party walls, 50mm air gap, then 4x2 studding around the area, rockwool between the uprights, then 1 skin of 18mm plasterboard, then 1 skin of 12mm plasterboard, dont go for the sound deadening plasterboards their density can in certain circumstances increase sound ingress. Between the 2 layers of plaster board we use a special compound called green glue, which is simply applied to the 12mm plasterboard prior to installation. It works at considerable reducing the sound the travels through the party walls, and after about 4 weeks it is even more efficient. If you want details on this product please let me know we are a distributor for the American manufacturer.
