PhoneStar TRI

Acoustic panels for effective soundproofing filled with high-density silica sand

A truly ingenious noise control product: corrugated cardboard filled with sand. On the one hand these panels are quite heavy (up to 29 kg/m²) which increases the effectiveness of each sound proofing construction. On the other hand the internal damping of the sand reduces resonances which leads to a raised sound insulation and an improved room acoustics. Wall, ceiling and floor constructions are realizable with Phone Star. In many studio projects we have successfully used the Phone Star TRI plate.

But as using any acoustical product does not guarantee the solution of every possible acoustical problem we are happy to advise you; benefit from our experience of two decades of studio construction and ask for your acoustical concept.

Product information

Phone Star combines three key criteria mechanisms for sound insulation:

  • High mass
  • Multiple layers
  • Low stiffness
