To evaluate acoustic pollution

To evaluate acoustic pollution, the sound power emitted by a sound source must be measured. This must be done in such a way that any kind of noise source, regardless of where it will later be used, can be quantified. One of the most accurate methods for measuring the sound power of small and medium sound sources is described in standard EN ISO 3741:1999 “Acoustics. Determination of sound power levels of noise source using sound pressure. Precision methods for reverberation rooms”. Eurovent chose this measurement method for the certification programme for air conditioners.
In 1994, the heat pump laboratory of CEIS (Centro de Ensayos, Innovación y Servicios, S.L.) was selected by Eurovent as an independent laboratory to perform the above measurements. The actual sound power measurements are carried out by the external laboratory UPLA at the Polytechnic University of Madrid.
