    Device for studying acoustic & mechanical noise Device for studying acoustic & mechanical noise Presentation Transcript

    • Device for studying acoustic & mechanical noise
    • Acoustic & Mechanical Noise Reader Condenser Mic
    • Noise Investigator and Helper
    • Tone Generator
    • Scanning a electromechanical device for mechanical noise
    • Scanning the vent-wall
    • Scanning the optical table
    • Airborne noise detection in hood
    • Mechanical vibration (noise) transmissibility test Tone generator : frequency generated from 100 to 600Hz
    • Mechanical vibration (noise) transmissibility test Three different sample holders tested Aluminum plate Acrylic plate Acrylic plate with less surface Diaphragm cut
    • Mechanical vibration (noise) transmissibility test result
    • Mechanical vibration (noise) transmissibility test Three different piezo – stage holder tested On the floor
    • Aluminum stage Aluminum stage holder+ piezo stage Polypropylene stage Polypropylene stage holder + piezo stage
    • Polypropylene stage with rubber cushion Upside down Polypropylene stage holder + piezo stage
    • Mechanical vibration (noise) transmissibility test result
    • Listen & see a specific band
