ACOUSTICAL ASSEMBLY TEST RESULTS: ASTM E90
9mm (~3/8") Magnesiacore vs ~15mm (5/8") gypsum board
​
[~15mm gypsum] + [metal stud & batts] + [~15mm gypsum] = STC 43
​
magnesiacore only wall [9mm] + [metal stud & batts] + [9mm] = STC 48
​
[9mm / goo / 9mm] + [wood stud & batts] + [~15mm gypsum] = STC 50
​
[9mm / goo / 9mm] + [wood stud & batts] + [9mm / goo / 9mm] = STC 55
​
[9mm / goo / 9mm] + [metal stud & batts] + [9mm] = STC 55
​
[9mm / goo / 9mm] + [metal stud & batts] + [9mm / goo / 9mm] = STC 60
