This draft standard is a complement to EN ISO 140-3 and specifies the laboratory measurement of the improvement of the sound reduction index of a wall or ceiling, when covered by an additional acoustical lining. Dependent on the application of the lining, the tests are carried out on a massive heavyweight wall or floor with its coincidence frequency near 125 Hz and without any abnormalities concerning its airborne sound transmission (like thickness resonances). The results, including the single number improvement values, can be used to compare and predict the acoustic performance of additional linings, when combined with walls or ceilings meeting the above mentioned conditions of low coincidence frequency and absence of abnormalities and having a mass per unit area at least ten times larger than that of the lining. As additional linings are often applied to more lightweight homogeneous massive walls, another basic wall is defined with a given coincidence frequency around 500 Hz. As a strong interaction of lining and wall is expected in this case, the results, including the single number improvement values, are limited to this type of basic walland may thus be mainly used to compare and estimate the acoustic performance of linings under similar conditions. If individual, non-standardised basic elements are used, the only way to state a single number result is to calculate the direct difference of the weighted sound reduction indices of the basic element with and without lining. This value depends on the features of the test facility and of the basic element and thus mainly allows a comparison of different linings under the same measuring conditions. This draft standard does not deal with the sound reduction improvement by linings on flexible lightweight structures such as timber frame floors or double leaf gypsum board walls.
