Abstract

Auf spezielle Standard-Gründungselemente installierte Vorrichtungen (nachherein auch Absorptionsbalken genannt), die den durch Fahrverkehr auf Gleisanlagen erzeugten hörbaren Luftschall autodynamisch mittels der axiomatisch bekannten physikalischen Mechanismen der Absorption/Dissipation in nicht hörbare Schwingungsenergiewellen umzuwandeln. Die Vorrichtung ist dadurch gekennzeichnet, dass sie aus einem balkenförmig gestalteten Bauteil (U-Profil aus Metall oder gleichwertigen verformbaren Stoffen in beliebigen statisch zulässigen Längen) mit quadratischem oder rechteckigem Querschnitt besteht, das an drei (3) Seiten und den Kopfenden völlig geschlossen ist. Die vierte (4.) Seite ist als offener Schalleintritt ausgebildet und so verkleidet, dass die von der Schallquelle abgestrahlte Luftschallenergie so widerstandsfrei wie technisch möglich in das Innere des Absorptionsbalkens und damit in das dort befindliche Granulat einströmen kann.

Devices installed on special standard foundation elements (also referred to as absorption beams) convert the audible airborne sound generated by road traffic on track systems into the inaudible vibrational energy waves by means of the axiomatically known physical absorption / dissipation mechanisms. The device is characterized in that it consists of a beam-shaped component (U-profile made of metal or equivalent deformable materials in any statically permissible lengths) with a square or rectangular cross section, which is completely closed on three (3) sides and the head ends. The fourth (4th) side is designed as an open sound inlet and covered so that the radiated from the sound source airborne sound energy can flow without resistance as technically possible in the interior of the absorption bar and thus in the granules located there.
