Noise complaints have quadrupled in Scotland since new laws to deal with the problem came into force. The following has been taken from the Scottish Government web site and may be of interest to our readers.
Loud stereos and televisions, shouting, barking dogs, rowdy parties and DIY are the main sources of complaints, according to Scottish Government figures.
It has been said
“Excessive noise can seriously affect people’s quality of life. This four-fold increase in complaints is an inevitable consequence of local authorities publicising their complaints service and thus increasing awareness. But nevertheless this shows the new legislation is working and that the public now have the chance to report problems and get a speedy response.
“Reassuringly, less than one per cent of complaints received require a fixed penalty notice. The rest are dealt with by a verbal or written warning, and confirm the quick deterrent system is effective.”
Figures presented at the Euronoise conference show that 40,000 domestic noise complaints were made in 2008, compared to about 10,000 a year prior to 2004 when new anti social behaviour domestic noise laws were introduced and councils and police set up and publicised 24/7 call centres to handle complaints.
The figures, from the Scottish Government Air, Noise and Nuisance Team, were presented at the eighth Euronoise conference held at the Edinburgh International Conference Centre and attended by 800 delegates from around the globe.
The European Acoustics Association asked the UK Institute of Acoustics to host this year’s event and Scotland was chosen in recognition of the work done by the Scottish Government and local authorities to implement the 2002 EC Environmental Noise Directive.

Noise from neighbours through any party wall, particularly at night is a particular problem that affects many people. Noise at night is always difficult to address because your normal background noises are usually switched off and when you are trying to get to sleep, noise from elsewhere can make it difficult. Noise that is intermittent is the worst kind because it is not so easy to get used to whereas, noise that is more constant such as outside traffic is more easy to get used to and over a short period of time, is no longer noticeable in many cases.
What can be done about it? Well this article is to deal with noisy neighbours so will involve the noise heard from the other side of a party wall and how to soundproof a party wall by stopping flanking noise. We will deal with outside noise in another article.
Now for the neighbour noise. Obviously the first thing that should be done is talk to them to explain the noise problem that is being heard. The best way to do this is to invite them round for a cup of tea or something stronger then bring up the subject. If you can replicate the sounds that are being heard from your side of the wall for your neighbour to hear, they would then have a greater understanding of the noise problem and hopefully, be more amenable to doing something about it so that your peace and tranquillity are restored. The last thing that should be done is to go hammering on their door because the noise is so upsetting. That would only antagonise them and make them less likely to co-operate. Co-operation is always more successful than confrontation. If all else fails then soundproofing is your last resort. If the property is pre-war with solid structural walls then any soundproofing measures will be more effective but if the walls are cavity walls with lightweight internal blocks then flanking noise is likely to be a problem. This is when noise flanks around the noise barrier and in the case of cavity walls, through the lightweight blocks and the cavity from one side of the wall to the other. If the cavity has been filled with foam type cavity wall insulation the problem will still be evident but if the cavity has been filled with blown mineral wool, this will act as a sound absorber and the flanking noise will be less noticeable. Flanking noise can also penetrate through the floors and ceilings if they are timber joist supported so before any work is started to soundproof the party wall, steps must be taken to reduce the flanking noise coming through the floor and ceiling.
Starting with the floor, if the floorboards are parallel with the wall then they will be easier to take up and only about four feet or 1.25 metres need to be removed to gain access to the joists. Once the floorboards have been removed, check for gaps where the joists are fitted into the party wall because gaps will allow any noise to penetrate from one side to the other more easily. If any gaps are found and they are simply small gaps then seal them with our flexible Acoustic Sealer but if the gaps are larger then they will have to be sealed with a sand/cement mixture. Once the joists are suitably sealed in the party wall, install as a loose fit, 100mm of AMW100 Acoustic Mineral Wool between the joists. AMW100 is supplied in slabs 1200 x 600 so they should be cut with a sharp knife so that you have a piece that is 1200mm long by just under the width of the joists then insert it so that one end is butted right up to the party wall. Offcuts can be used in the same way so there is no wastage. When complete replace the floor boards and screw them down. However, if the floorboards are perpendicular to the party wall then the joists will be parallel and so not so easy to remove a small section of the floorboards. So to compensate for this leave the floorboards alone and overlay with a double thickness of 2mm SBM5 Soundproofing Mat followed with a layer of polythene to contain any potential smells from this recycled sound insulation. Although smells are not usually a problem, because the sound insulation is produced from recycled materials some times a smell is evident and although not noxious, will not be desirable so the polythene will seal it in.
Now for the ceiling. If the ceiling is a top floor bedroom ceiling then it should be possible to check in the loft to see if the joists are correctly sealed into the party wall and if not, can be sealed as described earlier. If the joists are in the other direct and parallel to the wall then sound leakage will not be so much of a problem and it will be just the flanking noise to deal with and that can be addressed from below. From below all you have to do is screw up a 15mm layer of high density Acoustic Plasterboard with our 1mm SoundBlocker Membrane sandwiched between the new and old layers of plasterboard to break up the mass of the ceiling thus enhancing the noise blocking properties of the ceiling.
OK so now flanking noise through the floor and ceiling have been addressed you may wish to do something about flanking noise through the external structural wall if that is an issue and for this I suggest you fit our Thin Wall Soundproofing System. This system is only 45mm thick or 50mm if 15mm Acoustic Plasterboard is used and should be applied over the entire wall surface.

Flanking noise round a party wall has now been covered in this Blog.
