Presentation of the laboratory

During this semester, you will have the opportunity to have practical work on acoustics along various topics, among which:
  • initiation to Matlab programing to acoustics - analysis and synthesis of complex musical sounds
  • Simulation of physical sound sources and acoustic propagation on COMSOL Multiphysics, including loudspeakers
  • Sound absorption coefficient measurements of acoustic materials in an impedance tube
  • Sound absorption coefficient measurements of acoustic materials in a reverberant chamber
  • Room modes measurements in the reverberant chamber (COMSOL simulations + measurements)
  • Loudspeaker characterization in free field (COMSOL simulations + measurements)

This first week is devoted to programming Matlab codes for sound recording and analysis.

  • A 1st lab guides you through Matlab to unveil some signal processing tools for audio

  • The 2nd lab will allow you synthesize a piano notes mimicking physical features of such a sound.
