Case Todd · Answer 1

Coefficients of Absorption for Common Materials

Perforated acoustic ceiling material 60%

Heavy curtains 50%

Carpeting 20%

Wood 5%

Plaster 3%

Clay tile 3%

Concrete 2%

The answer is C. Heavy curtains

Athena Herman · Answer 2

I would say D. Concrete. It has more molecules packed together in a square shape ... The tighter the molecules, the less sound waves that are able to travel through the medium.
