With numerous acoustic considerations to take into account when carrying out a refurbishment, there is no single solution for compliance. It is clear, however, that planning is of the utmost importance, which should ensure that the nature and interaction of all the appropriate variables are assessed. Common challenges Residential developments being pursued for a material change of use tend to present a range of acoustic issues, with some more obvious than others. Those less apparent usually occur in cavity masonry party walls. A common source of sound test failure within this type of construction is the incorrect use of wall ties. The presence of mortar snots in the cavity would also cause sound leakage. When upgrading an original wall to a separating wall, the sound insulation achieved will depend upon the existing construction. Under these circumstances, the provision of a composite lining is generally thepreferred remedial solution. However, if further improvement is necessary, an independent plasterboard stud partition should provide the required acoustic performance. When refurbishing a listed building, any exposed glazed facades will need to be retained. Whilst this undoubtedly adds character, it also presents a challenge to meeting acoustic standards. One option is to refurbish the existing frames, by removing from the casing structure for treatment and then reinstalling. If this is not feasible, secondary gLazing can be placed behind the exposed glazing.
