• fyp WWCB untuk mr siroji . present mggu depan. tolong ak woi. plzzz la. :-) The unfinished WWCB has very good acoustic properties since the open surface structure allows for a high level of acoustic absorption. This is illustrated in Figure 11 for different board types and different constructions. Line A of this graph represents a 25 mm board fixed directly to a concrete substructure. Line H is a 25 mm board fixed with 24 mm space between the board and the substructure. The board for line I is a composite panel of 50 mm wood wool and 40 mm mineral wool fixed with a 40 mm space between the board and the substructure.
