Acoustic optimizations in the music rehearsal room

If you only want to improve the room acoustics, i.e. to dampen the room inside so that the acoustics and noise level are reduced for the people in the room or the hearing quality is optimized, we can recommend the following products with a thickness of 40 mm or more:

• Silphon® Trapezprofilschaumstoffe
  
• Silphon® Noppenschaumstoffe
  
• Silphon® UniversalStudioabsorber
  
• Silphon® Pyramidenschaumstoff Basotect G+ Melaminschaumstoff
  

For lower frequencies such as bass etc., a thicker foam of between 60 mm and 100 mm should be used - the thicker the foam, the better the absorption effect.

Conclusion:

High frequencies: 40-60 mm
Depth frequencies: 60-100 mm

If you prefer products with high fire protection and high quality and do not want to darken the room too much with the anthracite-colored absorbers, Basotect® G+ in the color light gray and Basotect® B in the color white are available.

This is referred to as noise insulation and can generally be achieved at a greater financial cost. The aforementioned nap foams, pyramid foams and trapezoidal profile foams are almost ineffective when it comes to sound insulation. Heavy panels must be used here to achieve sound insulation. These are, for example, composite foam panels or heavy foils such as Terodem and Teroform. The 140 kg/m³ composite foam board with a thickness of approx. 50 mm can be mounted on the wall. Glue a heavy foil such as Terodem or Teroform onto the composite foam board and, if necessary, you can glue on another composite foam board of 50 mm or more.

With this installation, you achieve efficient sound insulation by allowing the sound to penetrate the first composite foam panel and be attenuated. The sound waves then hit the heavy foil, causing it to vibrate, destroying further energy, and the next composite foam panel absorbs additional sound before the sound waves are attenuated and minimized and hit the wall. Boxes, amplifiers or drums are often placed directly on the floor; these should be decoupled from the floor so that structure-borne sound is not transmitted. The following products such as Sylomer or Vibra® 3D rubber granulate mats are available. You can find specific online advice on drum pedestals here: Drums.
