Acoustic Barrier Attenuation

Sound barrier insertion loss and noise reduction data for highway, industrial, and residential acoustic barriers — concrete, masonry, earth berm, metal, timber, acrylic, absorptive, jersey barrier, and composite types. Includes STC rating, octave-band transmission loss (125–4000 Hz), insertion loss at Fresnel numbers 5 and 10, NRC, lifespan, and installed cost per FHWA-HEP-10-025, ISO 9613-2, and Bies & Hansen Engineering Noise Control.
