Investigations on the Fundamental Suitability of Sprayed-on and Plaster-covered hygrothermic active Cellulose-Compact-Soundabsorber

Project: Research project

Description

Development of a new kind of spray-on and plastered noise absorber on the basis of cellulose from recycled paper. The absorber system preferably attenuates the low-frequency range, that can usually only be controlled with rather complex systems, and can also be used where conventional absorbers could cause problems due to impermissible water vapour condensation.
