EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 15186-1 testing. This standard specifies a sound intensity method for determining the sound attenuation index and the level difference of structural elements normalized by element.
The method can be used as an alternative to ISO 140-3 and ISO 140-10 respectively. An important use is when the traditional ISO 140-3 method fails due to high side transmission.
The repeatability of this density method is estimated to be equal to or better than ISO 140-3 .
Some information is given about the accuracy with which this part of ISO 15186 can reproduce the sound reduction index measured against ISO 140-3.
Ten times the logarithm of base 10 of the ratio of the square of the area and time average of the sound pressure to the square of the reference sound pressure, the area average occupies the entire room except for the parts where direct radiation is direct radiation.
In theory, the sound reduction index determined using the conventional measurement method ( ISO 140-3 ) was overestimated due to underestimation of the sound power emitted into the receiving room. To account for this fact, if the purpose of density measurements is to simulate measurements according to ISO 140-3, the density sound reduction index must be changed as above.
EUROLAB assists manufacturers with EN ISO 15186-1 test compliance. Our test experts, with their professional working mission and principles, provide you, our manufacturers and suppliers, the best service and controlled testing process in our laboratories.
