Description

BeschreibungDescription

Apparat zur Reduzierung bzw. Auslöschung von Lärm Nach Rücksprache mit einem Professor an der Hochschule in Frankfurt am Main soll dieses Prinzip im Fahrzeugbau bereits verwendet werden. Patent-Recherchen auch international waren ohne Erfolg.Apparatus for reducing or eliminating noise After consulting a professor at the university in Frankfurt am Main, this principle is already being used in vehicle construction. Patent searches, including international ones, were unsuccessful.

Ortsfeste sowie ortsveränderliche Anlagen, BertiebsstädtenrEinrichtimgeivMaschinenr Geräte, und Fahrzeuge emittieren Geäusch- und Schallwellen.Fixed and mobile systems, industrial facilities, machines, equipment and vehicles emit noise and sound waves.

Mit dem Apparat wird erreicht, dass vom Emittenden ausgesendete Geräuschbeziehungsweise Lärmwellen vom menschlichen Ohr in vernachlässigbarer weise wahrgenommen werden.The device ensures that the sound or noise waves emitted by the emitter are perceived by the human ear to a negligible extent.

Der ortsfeste oder ortsveränderliche Apparat empfangt die Schallwellen mittels eines bewegungsgelagerten, sensorgesteuert auch arretierbaren Richtmikrophon. Der Schall wird in ein wetterfestes Gerät weiter geleitet. Dort berechnet ein Programm auf Microchips die destruktive Interferenzwelle und den nötigen Schalldruck. Mittels Verstärker und Lautsprechern) (auch wetterfest) wird die entsprechende Schallwelle ausgesendet.The stationary or mobile device receives the sound waves using a motion-mounted, sensor-controlled and lockable directional microphone. The sound is passed on to a weatherproof device. There, a program on microchips calculates the destructive interference wave and the necessary sound pressure. The corresponding sound wave is emitted using amplifiers and loudspeakers (also weatherproof).

Ausgenommen wird der Einsatz im FahrzeugbauPlants, operating sites, facilities, machines, equipment and vehicles As well as mobile plants, operating sites, facilities, machines, equipment and vehicles. Use in vehicle construction is excluded

Beispiele: Einflugschneisen von Flughäfen, Baumaschinen, Eisenbahnunterführung, Autobahnen und deren Zubringern, Fabrikhallen.Examples: approach paths of airports, construction machinery, railway underpasses, motorways and their feeder roads, factory buildings.
