The accuracy of this standard can only be specified in detail after widespread comparisons with field data, which can only be gathered over a period of time after establishi

It is the responsibility of the user (i.e. a person, an organisation, the authorities) to address the consequences of the accuracy,

32、 inherent for all measurement and prediction methods, by specifying requirements for the input data and/or applying a safety margin to the results or applying some other correction.

BS EN 12354-5:2009EN 12354-5:2009 (E)5 Introduction The estimation of sound levels due to service equipment in buildings is a complex task and stru

35、cture-borne sources and transmission are not completely understood. In addition there are large variations between different equipment and installations and an installation often results in both airborne and structure-borne sources. This document contains a framework within which this subject can be

36、 treated. The main part (Clause 4) describes general models for sound transmission and related sources for ducts, airborne sound through buildings and structure-borne sound through buildings. For airborne and structure-borne sound transmission, parts 1 and 2 of EN 12354 are used wherever possible. I

37、n Clause 5 the application of these models to the different types of service equipment in buildings is addressed, specifying what is already known and available and what is not. Informative annexes give additional information on various aspects, related to sources and their sound production as well

38、as to specific aspects of sound transmission through buildings. Wherever possible references are made to available handbooks, literature or ongoing standardization work. Over the course of time some annexes or parts of them, especially those relating to the sound production by sources, can be delete

39、d when appropriate standards become available. For sound transmission through ducts there are standardized methods available to determine the sound power level of sources or the transmission loss of elements. Various handbooks are widely used for these estimations. For airborne sound transmission th

40、rough buildings information exists about sources and transmission, but some aspects that are particularly relevant to service equipment are less well known, such as the effect of acoustic near-fields, non-diffuse spaces and excitation and transmission at low frequencies. For these aspects some indic

41、ations are given as to how they could be treated and also as an indicator for the direction of further research and future improvements to the models. For structure-borne sound transmission similar solutions and problems exist as used for airborne sound. However, here the appropriate methods to char

42、acterize the sources for structure-borne sound excitation are just starting to become available, largely due to standardization work started within CEN (TC126/WG7) Therefore in this document a choice has been made to use a general quantity in the models, called “the characteristic structure-borne so

43、und power level“ of sources, even though there is no practical measurement method available at the moment. This allows the estimation models to have a general form that could be developed and refined in the future. For some types of equipment indications are given in an informative annex as to how t

44、his quantity can be deduced or estimated from available and current measurement methods, such as the ones already developed within CEN. The aim of this document is to provide a general basis for a practical approach to the estimation of sound levels due to service equipment. It also clarifies the ne

45、ed for work on source characterisation with an indication of areas where further research work is needed. BS EN 12354-5:2009EN 12354-5:2009 (E)6 1 Scope This document describes calculation models to estimate the sound pressure level in buildings due to service equipment. As for the field measurement

46、 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 others equipment attached to or

47、 installed in buildings. The estimation is primarily based on measured data that characterises 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 qua

48、ntities 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 descri

49、bed 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 dimensio
