About

Dr David Skulina gained his PhD in Musical Acoustics at the University of Edinburgh in 2006. His PhD thesis is entitled: 'A Study of Non-Linear Acoustic Flows at the Open End of a Tube using Particle Image Velocimetry'. This work focuses on the application of Particle Image Velocimetry (PIV) to the study of the acoustic velocity field at the open end of a tube in which a high amplitude sound field was generated by a loudspeaker. Phenomena such as vortex shedding and the formation of synthetic jets are observed and analysis is performed using vortex sound theory to quantify the acoustical energy loss due to vortex generation.

David has also piloted a study using Laser Doppler Vibrometry (LDV) into the operational deflection shapes of prototype loudspeaker diaphragms and holds a Bachelor of Science degree (with 1st class honours) in Physics with Music, also gained at the University of Edinburgh.
