Acoustic Lab

The technical equipment of the Acoustic Lab enables measurements to be carried out on components subjected to combined loads. Using electrodynamic shakers, components can be subjected to frequency-selective loads up to a frequency of 5 kHz in addition to their static/dynamic operating load. The Acoustic Lab is equipped with extensive state-of-the-art measuring equipment:

• 3 modal shakers (1 kN, 200 N, 10 N)
• Rotary laser vibrometer
• Fine balancing device with analysis functions
• Intensity measuring probe
• Free-field measuring microphones
• Extensive range of vibration transducers
• CAE Intensity Inspector for sound source localization

We also have a low-noise measuring room at the IMW. Common analysis methods are available for the machine acoustic assessment of machine structures:

• Sound power determination according to DIN EN ISO 3744, DIN EN ISO 3745, DIN EN ISO 9614-1 and -2
• Experimental modal analysis
• Acoustic resonance analysis for component diagnosis
