Abstract

Die Erfindung betrifft eine Vorrichtung (1) zur akustischen Messung von Luftschallwellen zur Anordnung in einem Fahrzeugprüfstand, wobei die Vorrichtung (1) zumindest ein Mikrofon (13) zur Aufnahme von Luftschallwellen und ein das Mikrofon (13) umgebendes Gehäuse (2) aufweist, wobei das Gehäuse (2) zumindest eine Öffnung (10) zum Durchgang der Luftschallwellen von außen zum Mikrofon (13) aufweist. Aufgabe ist es, eine besonders robuste Vorrichtung anzugeben, die Störgeräusche verringert. Diese Aufgabe wird dadurch erfüllt, dass zumindest ein erstes Schutzelement (3) in der Öffnung (10) angeordnet ist, das zumindest ein erstes Gitter, das einen Eintritt von Partikeln in das Gehäuse (2) verhindert, besitzt und zumindest ein zweites Schutzelement (7) in der Öffnung (10) angeordnet ist, das das Entstehen von Störgeräuschen einer Luftströmung verringert.The invention relates to a device (1) for the acoustic measurement of airborne sound waves for arrangement in a vehicle test bench, the device (1) having at least one microphone (13) for recording airborne sound waves and a housing (2) surrounding the microphone (13), wherein the housing (2) has at least one opening (10) for the passage of the airborne sound waves from the outside to the microphone (13). The object is to specify a particularly robust device that reduces background noise. This object is achieved in that at least one first protective element (3) is arranged in the opening (10), which has at least one first grille that prevents particles from entering the housing (2) and at least one second protective element (7 ) is arranged in the opening (10), which reduces the occurrence of noise from an air flow.
