The sound in the test room, produced as airborne sound radiated from the object, is measured. The source sound power is then estimated from the measured sound corrected for background noise, and from the measured reverberation time of the test room. Later in the process of calculation, a single value descriptor for the source sound power is calculated (see Clause 10). SIST EN 15657-1:2009

EN ISO 140-3:1995, Annex F. 6.2 Requirements for the acoustic measuring equipment The measuring equipment shall comply with the requirements of EN ISO 140-3:1995, Clause 4. 6.3 Requirement for the vibration measuring equipment The vibration transducers used shall be calibrated according to ISO 16063-21:2003 and fixed according to ISO 5348:1998. 7 Test facilities 7.1 Test room 7.1.1 Construction requirements For airborne sound measurements, the test room shall have a volume of at least 50 m3. Each of the test room walls shall not be less than 3,5 m wide and shall have a minimum mass per surface area of 230 kg/m2 if the equipment is directly connected to it. 7.1.2 Acoustic requirements According to EN ISO 140-1:1997, the reverberation time shall be in the range 1s - 2s.

Key 1 Resilient material Figure 1 — Schematic drawing of the three plate test rig The three plates shall be isolated from each other (see Figure 1), the corresponding velocity level difference, measured according to EN ISO 10848-1 without the equipment installed, being greater than 10 dB in each frequency band. The three plates shall be made of concrete (density of 2300 ± 200 kg/m3), have a thickness of 10 ± 1 cm, a minimum surface area of 5 m2 and preferably more than 7 m2, a ratio length/width close to 2 and a minimum loss factor at low frequencies (50-100 Hz) of 8 %. The loss factor η can be estimated from the structural reverberation time Ts of the plate using: η = 2,2 / (f Ts) (1) The minimum dimension of the plates must be equal or greater than the maximum dimension of the specimen. The specimen must not overhang the edge of the reception plate when installed. The example of an existing three plate test rig is given in Annex D. 8 Mounting of the specimen The mounting is performed exactly according to the instructions given by the manufacturer (or distributor or other interested party) of the product; it shall be described in full detail in the test report. The bathtub is measured with skirt according to the instructions given by the manufacturer. If the three plate test rig is located in the test room, the measurement of airborne and structure borne sound power can be made sequentially on the same setup of the specimen; the bathtub is connected to the three plate test rig as in real building, according to the instructions given by the manufactur
