Infrastructure and equipment

Currently coordinated by Prof. Julio Apolinário Cordioli, LVA has a state-of-the-art infrastructure for the development of teaching, research and extension work in the area of acoustics and vibrations. This infrastructure includes:

  • Two reverberating chambers;
  • A semi-anechoic chamber;
  • An anechoic chamber for aeroacoustic tests;
  • A temperature-controlled chamber (-30°C to 50°C / -22°F to 122°F) for vibration testing;
  • Tank for calibration of underwater acoustics equipment;
  • Critical listening room with speaker arrangement for virtualization of sound sources;
  • Experiment rooms and garage for car testing;
  • Classrooms and meeting rooms;
  • Various digital analyzers and multi-channel acquisition systems (B&K, LMS, NI, Head-acoustics, etc.);
  • Wide range of transducers for acoustic and vibration testing (accelerometers, microphones, pressure sensors, laser vibrometers, impedance heads, impact hammers, magnetic vibration sensors, hydrophones, etc.);
  • Wide range of equipment for acoustics and vibration testing (NPS meters, NPS and vibration calibrators, speakers, electrodynamic exciter, power amplifiers, turntable for microphones, oscilloscopes, impedance tube, etc.);
  • Equipment for subjective acoustic testing (KEMAR and HeadAcoustics artificial head and torso, equalizers, headphones, speakers arrangement for acoustic virtual reality, etc.);
  • AC40 interacoustics audiometer with circum auricular, supra auricular and insert headphones;
  • Various experimental analysis software (B&K Pulse, LMS Test.Lab, NI Labview, HeadAcoustics Artemis, etc);
  • Various numerical simulation software (ESI VA-One, LMS Virtual.Lab, MSC Nastran/Patran, COMSOL, etc.).

Here are some of the acoustics and vibration tests that LVA is able to do:

  • Experimental modal analysis;
  • Sound power measurement;
  • Measurement of the acoustic absorption coefficient of materials;
  • Characterization of visco-elastic materials;
  • Sound transmission loss measurement;
  • Measurement of electroacoustic parameters of speakers.
