This high quality acoustic product is made on our precision machinery according to DIN 7715 Part 5 P3.

In the production (foaming) of this acoustic material different sized pores (voids) can arise. Voids are typical for the material, do not represent a quality defect and do not affect the acoustic properties of the absorber.

For those who expect more - aixFOAM Premium sound absorbers

Our sound absorbers made of thermoset acoustic foam are the ideal solution for rooms with particularly high soundproofing and fire protection requirements. They owe their unsurpassed acoustic properties to the extremely fine, open pore structure that almost completely absorbs sound. They are flame retardant without the addition of flame retardants and thus meet many regulations to ensure fire safety in public buildings.

Sound absorber/ sound insulation in the reverberation chamber when determining the absorption values
  • Maximum sound absorption
  • Flame retardant according to DIN 4102 B1
  • Form-stable and colour-fast – no yellowing!
  • Very low weight
  • Antistatic, fibre-free and elastic

Absorption values

The measurements of the sound absorption coefficient were determined according to DIN EN ISO 354 (reverberation room) and refer to an absorber area of 100 cm x 50 cm.
