Acoustic reduction

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

Test carried out as per the UNE-EN-ISO 140-6:1999 standard in LABEIN
