Course content

improving non-invasive techniques for measuring the acoustic impedance, impulse response and internal geometry of ducts such as musical wind instruments, airways and pipeline sections. Such techniques include acoustic pulse reflectometry, a two-microphone-four-calibrations impedance measurement procedure, and capillary-based impedance measurement methods. The group is also involved in developing acoustical methods for the non-invasive monitoring of soils and the roughness of water channels.

The research is carried out by PhD students working individually or in collaboration with the group’s other PhD students, postdoctoral researchers and academic staff.

Potential research projects

Projects in all of the above areas are possible. Also, please approach us if you are interested in another topic that remains within the broad interests of the research group.
