Except for the valve, all parts are made from composite materials: glass fabric, para-aramid fabric and epoxy resin as well as a sound-absorbing textile glass compound. T he noise reduction system is designed and used by the railroad industry for track workers when coupling train cars. Its main goal is to protect the hearing of railroad personnel when testing the brakes of trains by reducing the noise Due to the use of composites, the level to only 75 dB versus 120 dB for device weighs 800 g versus 1800 g for traditional systems. earlier devices. A second version is also equipped with a pressure control The device consists of a connector system that notifies the operator if 2012 年 11 年 07-09 年 JUNE 26. 27. 28 . 20l2 JEC - 25 bd de l’Amiral Bruix -75116 Paris - France www.jeccomposites.com TCI’s noise reduction system Stickers Asia 2012.indd 1 14 jec composites magazine / No73 June 2012 07/12/2011 18:22:07http://www.jeccomposites.com
