Acoustic bricks, Fair tunnel, Karlsruhe

Made of fired clay, Hagemeister acoustic bricks feature specific material properties which are highly effective in abating sound and avoiding the reflection of sound waves. In accordance with Germany's ZTV-Lsw 88 (supplementary technical directive on nois

e barriers), clay brick constructions are certified to reduce sound levels by as much as 10 db, depending on type. The sound absorbent effect of Hagemeister acoustic bricks has been proven through independent sound absorption tests. By specifying Hagemeis

ter acoustic bricks, architects and planners opt for a sophisticated, permanent, purely natural and high-quality solution which lends itself to a wide range of soundproofing applications.
