Floor Impact Isolation Testing

Categories: ,



Multi-Channel Measurement System + SAMURAI Software + SAMBA Software option by SINUS Messtechnik GmbH + Microphones

Laboratory or field in-situ testing of floor impact isolation, may be conducted in accordance with a range of international standards using a multi-channel measurement system plus SAMURAI software, including the Building Acoustics (SAMBA) Software Option. The multi-channel measurement system may include the SoundBook or NoisePAD, or the Expander/Apollo/Apollo Lite Boxes plus laptop, all by SINUS Messtechnik GmbH.

Field of Application:

The transmission of impact sound through various floor/ceiling construction details are important properties to quantify when specifying tiling or other floor covering materials..

The SAMURAI Building Acoustics (SAMBA) Software Option is used to measure impact sound transmission between adjacent vertically separated spaces from which impact sound insulation indices and ratings may be determined.


Apart from reverberation time measurements (which are already included in the basic SAMURAI acoustic software bundle), the Building Acoustics (SAMBA) Software Option enables the source, receiving and background noise spectra to be measured and the data organized into a format suitable for analysis according to the standard selected. The measurements and reporting functions are integrated in the software into a cohesive and clear user interface. The excitation of the receiving room can be performed with noise, impulse or sine sweep signals played through a suitable amplifier and speaker system, with a tapping machine as the impact source.


Measurement range

50 Hz to 5 kHz

Software overview

  • Clear navigation including status display
  • Management of source/receiving rooms and transmission paths
  • Management of additional information such as manufacturer, operator, company, address, description, building volumes, areas etc.
  • Selectable frequency ranges (100 … 3150 Hz or 50 … 5000 Hz)
  • Measurement in the receiving room of reverberation time spectra EDT, RT15, RT20, RT30; automatic or manual fitting of linear approximations to level decay curves, backward integration selectable
  • Averaging of results from selected positions and measurements
  • Usage of internal or external signal generators
  • Flexible creation of measurement reports according to standards
  • Export and printing of the results
