Acoustic control within buildings can be a complex area traditionally  involving either specialist consultants or a purely subjective approach. However, higher density living and the growth in noise sources today have increased awareness and driven measures to reduce problems resulting from noise pollution.

In particular, Part E of the Building Regulations 2003, as amended in 2004, 2010, 2013 and 2015 includes quantifiable acoustic performance levels to ensure reasonable conditions in a wider range of residential buildings. It also establishes requirements for schools, linked to Department for Education guidance. Although not regulated, the best approach to non-residential building types should also be reconsidered along similar lines.

The effects of acoustic privacy and nuisance noise are subjective and influenced by background noise within the room, distance from sound source and general context, amongst others. When considering walls containing doors, the combined performance of both elements may be relevant: with the proportion of door to wall being particularly important.

Whether or not required by law, the latest generation of acoustic doorsets is capable of satisfying useful sound reduction requirements economically.
