Acoustic Barriers A complete range of certified, high performance solid and louvred acoustic barriers to solve a wide variety of environmental noise pollution problems. • • • • • Guaranteed, proven, sound reduction Sound absorptive surfaces minimise reflected noise Rugged, abuse-resistant, long-lasting steel construction Weather resistant and almost maintenance-free Wide choice of finishes to blend with individual landscapes A Complete Range of Barrier Systems Absorptive Free standing barrier systems - Type FS and SFS - are sound absorptive on one or both sides, offer excellent sound transmission...

Free-standing Solid Barriers Barrier Attenuation Theoretical attenuation, provided by solid barriers, is shown on the graph below. In practice, the maximum barrier attenuation cannot be greater than the barrier’s sound transmission loss (STL). Fresnel Number Where: Sound absorptive surfaces reduce reverberant build-up between parallel barriers and other reflective surfaces and increase the ability of barriers to attenuate noise. Acoustic Performance All IAC Acoustics Noishield™ barriers offer exceptional transmission loss characteristics and incorporate proven, sound absorbing materials which...

Acoustic Barriers Installation & Maintenance We offer a full design, delivery and installation service, which can also include all necessary structural steelwork. Barriers can be erected by IAC’s own, trained personnel. Alternatively, they can be installed by others (contractors, end users etc), preferably under the supervision of an IAC Acoustics engineer. All IAC Acoustics barriers have guaranteed, rust-proof finishes. Periodic cleaning can be undertaken using water/mild detergent. More stubborn stains and graffiti can be removed using harsher cleaning chemicals, though we only recommend these...
