  • Noise monitoring solutions for sound intensity mapping

    Sound Intensity is the measure of acoustic energy passing through a unit area. By integrating over a surface enclosing an object under test, you can calculate the object`s sound power. This can be done regardless of background noise, allowing convenient, in situ measurements of sound power. Other advantages of sound intensity measurements include the ability to determine the directionality of sound, and to quickly localise noise `hot spots`. Mapping software takes this a stage further by providing you with a...

  • 2-Channel sound insulation for building acoustics

    Façade sound insulation is measured like sound insulation between rooms, except that one `room` is actually open space. The sound level is measured inside the receiving room and outside the façade of the building. The level difference is then corrected for the influence of the reverberation time and background noise level in the receiving room. Finally a single-number index is calculated by averaging over all the frequency bands. A loudspeaker source can be used for the measurement, giving a choice...

  • Sound Insulation solutions for building acoustics

    Sound energy does not remain in the room where it is produced, but propagates throughout the building by any available path, intruding into other rooms as noise. Each country has its own standards of sound insulation in buildings, but it is measured in the same way all over the world. The noise levels in the two rooms under investigation are measured and subtracted, and the level difference is corrected for the influence of the reverberation time and background noise level in the receiving room. The measurements...
