Definitions

  • the invention relates to an arrangement of an applied on the inside of a building exterior wall sound-absorbing element and a method for its preparation.
  • Sound-absorbing elements which can be attached to walls or ceilings play an important role in structural engineering for damping environmental noise and influencing the frequency response of rooms.
  • the reverberation time of rooms can be shortened and the formation of resonance sound, which is caused by unfavorable dimensioning or geometry of the space caused standing waves, can be reduced.
  • the attenuation of frequencies below 100 Hz is often associated with considerable effort or previously had an unsatisfactory architectural appearance.
  • Prior art sound absorbing elements E04B are widely constructed as plate resonators, such as in U.S. Pat EP 0 811 097 described.
  • Plattenresonator for broadband attenuation of rooms includes a thin front panel made of metal, which is excitable at sound waves below 125 Hz for resonant oscillation, further a back plate made of an elastomer, and a full-surface solid connection between the front panel and back plate, for example by double-sided adhesive tape and, finally, a boundary which is closed on all sides by the back plate and does not hinder lateral sound entry into the back plate.
  • This plate resonator can be attached to the ceiling or wall using edge fasteners.
  • an arrangement of a sound absorbing member applied to a ceiling or wall is known.
  • the element has a construction of a lower layer with cellulose and a surface layer connected to the lower layer, which has a higher specific gravity than the lower layer.
  • a disadvantage of this known sound-absorbing element is the fact that it can develop satisfactory effect only in small rooms, if one does not accept that the sound-absorbing element is sized as large as the wall or ceiling to which it is attached. Since the latter is hardly feasible for visual and practical reasons, the sound-absorbing element can only "punctually" in Space act.
  • Another disadvantage of the known sound-absorbing element is that its attachment has to be done very carefully and optionally with the use of vibration damping elements so as not to become the cause of resonant vibrations that can lead to unpleasant noise.
  • vibration damping elements In the attachment of the known sound-absorbing elements to the wall or ceiling, there is also the risk of the formation of sound bridges by sound impinging on the sound-absorbing element via the fasteners is forwarded to the masonry.
  • the known sound-absorbing element also has a problem that it acts as an internal insulation without vapor barrier in the case of application to the inside of a building exterior wall and can lead to condensate formation at the boundary layer to the masonry due to dew point shift. This can lead to mold growth.
  • the above-mentioned moisture problems become greater, the greater the area proportion of the known sound-absorbing elements in comparison to the sum of the wall and ceiling surfaces.
