Open Plan Office Module

With the release of version 1.4, IRIS can come equipped with a powerful set of tools for Open Plan Office measurements. The new tools will measure:

  • Spatial decay rate (D2,S)
  • Level of speech at 4 m from source (Lp,A,S,4m)
  • Distraction distance (rd)
  • Privacy distance (rp)
  • VDI 2569 room acoustic class

These new metrics are calculated according to procedures detailed in two recently published office acoustics standards, ISO 3382-3:2012 Acoustics -- Measurement of room acoustic parameters -- Part 3: Open plan offices and VDI 2569:2016-02-Draft Sound protection and acoustical design in offices.

These features are available in the Open Plan Office module, an add-on option to base installations of IRIS for versions 1.4 and higher.

Please contact your nearest distributor for pricing details.

What people are saying

  • I regard the acoustic designs of Marshall Day Acoustics to be amongst the finest and probably the most innovative in the world.

  • The success of a musical performance depends on the sense of proximity of performer to listener. This sense is mediated largely by the directional properties of the reflected sound field.

    Sir Harold Marshall
  • Marshall Day Software is like having an acoustic laboratory in the palm of your hand.
