Prosonic External Acoustic Rubber Panels


Recycled rubber acoustic absorption panels designed specifically for external use.

Ideal for reducing the reverberation time (and hence omni-directional reverberant sound pressure levels) in road tunnels, railway sidings, construction sites, loading yards etc.


Panels are simply bolted to the substrate. The additional internal cavity depth improves low frequency absorption.
