SOUNDMIX 350 Plus is a complex made up of a sheet of synthetic EPDM rubber, of 2 kg/m2, which has a sheet of 2mm-thick high-density reticulated polyethylene adhered to one side of it.
SOUNDMIX GM/ON between a single direction framework (25 + 5 cm) and a 5 cm thick layer of cement on top gives the following results in acoustic reduction:
|Rw (C; Ctr)||= 57 (-2; -7)||dB ISO 717-1 to airborne noise|
|R (A)||= 56,4 dB(A)||NBE CA-88 to airborne noise|
|Ln,w (Ci)||= 58 (-1)||dB ISO 717-2 to impact noise|
|Ln(A)||= 65.4 dB(A)||NBE CA-88 to impact noise|
