Scope

This document describes calculation models to estimate the sound pressure level in buildings due to service equipment. As for the field measurement document (EN ISO 16032) it covers sanitary installations, mechanical ventilation, heating and cooling, service equipment, lifts, rubbish chutes, boilers, blowers, pumps and other auxiliary service equipment, and motor driven car park doors, but can also be applied to other equipment attached to or installed in buildings. The estimation is primarily based on measured data that characterizes both the sources and the building constructions. The models given are applicable to calculations in frequency bands. This document describes the principles of the calculation models, lists the relevant quantities and defines its applications and restrictions. It is intended for acoustical experts and provides the framework for the development of application documents and tools for other users in the field of building construction, taking into account local circumstances. The calculation models described use the most general approach for engineering purposes, with a link to measurable quantities that specify the performance of building elements and equipment. The known limitations of these calculation models are described in this document. Users should, however, be aware that other calculation models also exist, each with their own applicability and restrictions. The models are based on experience with predictions for dwellings and offices; they could also be used for other types of buildings provided the constructional dimensions are similar to those in dwellings. This revised version better takes into account low frequencies down to 50 Hz and allows predictions in lightweight constructions.

Purpose

Reactivation of WI 0126123
