Horizontal elements for

DELTA chamber

It consists of two identical reception rooms on which have first set up the support frame of the test sample and the mobile emission room realizing a couple of reverberant rooms. These three rooms are in accordance with NF EN ISO 10140-5 (ex – NF EN ISO 140-1) and NF EN ISO 15657-1.

This testing facility is designed to acoustical evaluation of any kind of horizontal element (floors, flooring, roofing, skylights …)

Evaluation can be done with respect to airborne noise (NF EN ISO 10140-2 (ex - NF EN ISO 140-3)), impact noise (NF EN ISO 10140-3 (ex-NF EN ISO 140-6, 8 ans 11) and NF S 31-074) and rainfall noise (NF EN ISO 10140-1 amd 2 and NF EN ISO 10140-5 amd 1pr )

In this facility, we also have implemented the reception plate method in order to measure airborne and structure borne noises generated by equipments (SPA, compressor…) according to NF EN ISO 15657-1.

Main characteristics :

  • Low background noise ("box in a box" system for all three rooms)
  • Referent concrete floor of 140 mm
  • Referent light weight floor, type 1 according to NF EN ISO 140-2 (ex-NF EN ISO 140-11)
  • R’maxw = 80 dB for heavy floors
  • R’maxw = 74 dB for light floors
  • Max. testing surface 15 m²
