Noise level reduction values of Sound-STOPcubes®

The below-mentioned sound level reduction values were determined in fully assembled Original-Sound-STOPcubes® in both Standard and Premium versions.

The tested Sound-STOPcubes® were fitted with an entrance door with windows (Premium version with 2 doors), different window configurations on the longer cube side, standard fittings including ventilating system and air conditioning unit, as well as wiring in the wall elements.

The tests were carried out by a public appointed and authorized appraiser of noise emmissions and pollution - Dipl. Ing. Arno P. Goldschmidt of the IHK (Chamber of Industry and Commerce) Lübeck.

We would be happy to provide the official test documentation on request.

 

The tests were carried out at four different positions of each Sound-STOPcube®, namely:

  • Entrance door
  • Window side
  • Ventilation system / air conditioning system / cable outlets
  • Closed end wall

Measurements: inner generation / outer reception - without additional absorber on the cube walls.

The below-mentioned figures comply with the average determined values with a tolerance margin of +/- 3dB.
