Swedish building regulations set limits on the A-weighted equivalent and maximum sound pressure levels from service equipments in dwellings, schools, offices and hospitals. In bedrooms, a special limit is given as a C-weighted equivalent level. Furthermore, Swedish environmental regulations introduced other limits in 1996, on the room average sound pressure levels in third octave bands 31,5-200 Hz. Until recently, measurements have been conducted according to national standards or guidelines, but there has been a request to refer to international standards rather than national. For this purpose, a new guideline has been developed. Measurement procedures have been described, one for the standard EN ISO 10052 and one for the EN ISO 16032. Several changes as well as some new instructions had to be included to make measurement results compatible with the national requirements, e.g. using third octave bands rather than octave bands. The standards focus on sound from one type of source at the time, whereas in our regulations, sound in rooms may stem from multiple sources. Hence, the guidelines had to describe measurement conditions as well as define handling of background noise in some detail.
