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)
The first session will consist in an introduction to the labs, explaining the connection with the Audio lectures, followed by a quick tour of the facilities.
The actual laboratories will start the following week.
This first week is devoted to programming Matlab codes for sound recording and analysis.
The 2nd lab will allow you synthesize a piano notes mimicking physical features of such a sound.
