Abstract (en)
[origin: EP1950357A1] The sound-absorbing absorption element has a baseplate from glass, which has a micro slot with a width between 0.05 and 1 millimeter, particularly between 0.1 and 0.9 millimeter. The micro slot is formed by an open surface particularly from 0.8 to 18 percent related to a surface of the baseplate. The micro slot concentrates multiple uneven micro slots in the baseplate that is distributed in individual ranges of the baseplate. An independent claim is also included for a method for production of sound-absorbing absorbent element.
