With larger values of t of about 6 to 12 mm, material with excellent acoustic properties is obtained which can be used (for example in a sound studio) for sound absorption). Wells of such great depth t are more likely to be referred to as "honeycombs" (and the resulting structure rather than “honeycomb”).
  • the subject matter of the invention therefore continues to be the use of the damping layer according to the invention for sound absorption.

  • the wall material of the recesses lying between the two planes has a stiffening effect, because it is loaded only in its longitudinal direction when loaded from above (for example, tread loading in an artificial turf).
