Title
(EN) SOUND DAMPENING AND PASS THROUGH FILTERING
(FR) AMORTISSEMENT SONORE ET FILTRAGE TRAVERSANT
Abstract
(EN) A sound monitoring system (60) for collecting and processing an environmental noise level surrounding a work machine (20) is disclosed. The sound monitoring system (60) may include an acoustic sensor (52) having a plurality of microphones (54) arranged into a signal detection array to capture the environmental noise level and generate an acoustic output signal. Additionally, the sound monitoring system (60) may include a controller (44) communicably coupled to the acoustic sensor (52) and programmed to perform a signal processing to identify a first portion and a second portion of the acoustic output signal. Furthermore, the controller (44) may be programmed to generate a controller output signal based on the first and second portions of the output level. A speaker (80) may be located on the work machine (20) and communicably coupled to the controller (44) such that the speaker (80) receives and emits the controller output signal.
(FR) L'invention concerne un système de surveillance sonore (60) destiné à collecter et traiter un niveau de bruit environnemental entourant une machine de travail (20). Le système de surveillance sonore (60) selon l'invention peut comprendre un capteur acoustique (52) pourvu d'une pluralité de microphones (54) agencés dans un réseau de détection de signal pour capturer le niveau de bruit environnemental et générer un signal de sortie acoustique. En outre, le système de surveillance sonore (60) peut comprendre un dispositif de commande (44) couplé en communication au capteur acoustique (52) et programmé pour effectuer un traitement de signal afin d'identifier une première partie et une deuxième partie du signal de sortie acoustique. De plus, le dispositif de commande (44) peut être programmé pour générer un signal de sortie de dispositif de commande en fonction des première et deuxième parties du niveau de sortie. Un haut-parleur (80) peut être situé sur la machine de travail (20) et couplé en communication au dispositif de commande (44) de sorte que le haut-parleur (80) reçoive et émette le signal de sortie de dispositif de commande.
