"A 0.96 sone rating means total silence." Fact: Total silence (0 sones) is physically impossible in an occupied space. 0.96 sones is the threshold of human hearing—effectively silent for practical purposes.

This is where "full" matters. Use and acoustic sealant along all four edges of each panel. Acoustics follow air: if air passes, sound passes. A full sheet with sealed edges maintains the 0.96 sone rating. Unsealed edges drop you to 2.5 sones. sone096 full
