[GSBN] SB & Acoustics

[Graeme North]

Hi Sarah

Acoustic separation is mainly due to mass. although some deflection can occur.

Is this a temporary or permanent structure they are looking for?

Durability of an exposed landscape s/bale wall probably not reliably much more than an open pile of strawbales  - but will act as a great formwork for a plaster base if you are OK with it hollowing out over time - 

Might be a great experiment

cheers
