Acoustic Barrier Attenuation: timber_fence
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.
| barrier type | material | Fresnel number method | STC rating (dimensionless) | TL 1000Hz dB (dB) | TL 125Hz dB (dB) | TL 2000Hz dB (dB) | TL 250Hz dB (dB) | TL 4000Hz dB (dB) | TL 500Hz dB (dB) | barrier height ft (ft) | cost per sf installed (USD/sf) | expected lifespan years (years) | insertion loss dB at 10dB Fresnel (dB) | insertion loss dB at 5dB Fresnel (dB) | surface density lb per ft2 (lb/ft2) | weather resistance |
