Unless requirements are laid out in codes, control of noise in buildings is often an afterthought. The measures taken to control noise, however, are invariably linked to other building subsystems. Mechanical and plumbing subsystems generate noise; the design of walls, ceilings and floors affects sound transmission.
This paper addresses four topics:
- sound transmission through concrete blocks
- plumbing noise
- flanking noise
- noise leaks.
It assumes a certain background in acoustics and will explain briefly only those terms and ideas relevant to the topics under discussion. Readers not familiar with some of the basics of noise control are referred to BSI '85 Noise Control in Buildings and the C MHC publication Noise Control authored by IRC research officers.
