JBER 24 Pack Charcoal Acoustic Panels 2" X 12" X 12" Studio Foam Wedges Fireproof Soundproof Padding Wall Panels

Haven't really tested the product, But they claimed that it's a "Rapid Expansion" Which is clearly not, It took 3 days to expand, Some of the panels aren't fully expanded, But the more you wait the better expansion.

Utilisé derrière mon frigo pour en atténuer les bruits car il siffle fort, le résultat est parfait, j'entends plus rien.

やはり両面テープでは接着しません。

مكتوب انه ٢٤ قطعه وياتي ناقص اربع قطع اي انه ٢٠ قطعه فقط وكتب للبائع ولم يرد او يحاول الرد على هذا النقص

Très bien. RAS
