Description

8002653-7 består av en reflekterande yta.
Genom att absorbenterna 2 placeras i hörnet l mellan vägg och tak bryts rumsmoderna och en effektiv ljudabsorption erhålles även vid frekvenser under 50Hz.
En lämplig utföringsform av uppfinningen kommer härnedan att närmare beskrivas under hänvisning till bifogad ritning.
Ritningen visar med schematisk genomskärning ett hörnparti 1 av ett rum med en plan akustisk absorberande skiva 2 anordnad i direkt anslutning till och i vinkel 4 mot ett hörnomrâde mellan vägg och tak. Skívornas ljudabsorptionsyta är vänd mot lokalens inre, och i hörnomrâdet l bakom skivorna 2 är inneslutet en luftvolym så att skivorna ha membranverkan, varjämte lokalens innertak består av en reflekterande yta. Det ljudabsorberande materialet 2 är placerat i ett ramsystem 3 direkt anslutet till vägg och tak.
