It
32、 is the task of WG 7 to prepare laboratory test methods to determine the source characteristics, while WG 2 concentrates on the method predicting the airborne and structure borne sound levels produced in the buildings; the prediction method, described in standard pr EN 12354-5, is based on power flo
33、w considerations and uses the laboratory test results as input data. The link to WG 2 is explained in more details in an informative annex (Annex B). The quantities considered in this standard are the following: a) the airborne sound is characterized by the airborne sound power radiated by the equip
34、ment; this power is calculated from the airborne sound measured in a test room in which the equipment is mounted b) the structure borne sound is characterized by the structural power injected by the equipment to the receiving structure to which the equipment is connected. Since in general the equipm
35、ent is connected up to three building elements (two walls and one floor), a three plate test rig is used and three structural power components are determined, calculated from vibration velocities measured on the plates. When the equipment is mounted on low mobility structures (having point mobilitie
36、s much lower than the mobilities measured on the equipment), the coupling between the source and the receiving structure is simpler and the way of transforming the power components measured in laboratory into the power components injected in situ to the building elements, greatly simplifies. This fi
37、rst part (part 1) of the standard is restricted to these simplified cases; a second part (part II), applicable to the other cases will be a future task of WG 7 and is not available yet.

38、ontrolled Copy, (c) BSI prEN 15657-1:2007 (E) 5 1 Scope Part 1 of the standard should apply to any source receiver configuration where the receiver mobility is 10 dB below the source mobility (see definition of mobility in clause 2 below). However, part 1 is restricted for the moment to whirlpool ba
39、ths since only this type of building equipment has been experimentally studied so far; for other types of building equipment, the principle of the method is still valid but some details in the standard might not be relevant. Therefore, this first part: specifies methods for the measurement under lab
40、oratory conditions of airborne and structure borne sound produced by whirlpool baths connected to low mobility structures. For the case of whirlpool baths, building structures of mass per unit area equal or greater than 220 kg/m2, hollow elements excluded, are considered as low mobility elements. de
