The effect of lining reveals with sound absorbent material

R.W. Guy, A. de Mey

Abstract


The sill and reveal of a panel or window system are known to influence the acoustic transmission of the system and it is known that lining the reveal with sound absorbent material can increase the sound reduction index. This work examines the influence of a window to sill or reveal ratio upon the known effects, by testing two window sizes whilst maintaining sill or reveal depths. The potential for marked increase in sound reduction index by reveal absorbent lining is also examined and deductions concerning its use are made
