Self-similarity in supersonic jet noise
Dr. Tracianne B. Neilsen, currently a part-time professor at Brigham Young University, earned her doctorate from the University of Texas at Austin, and completed a postdoctoral appointment at the associated Applied Research Laboratories. Her research areas include management and analysis of large acoustic data sets, numerical modeling of acoustic fields, and application of multi-dimensional inversion techniques to measured data for source characterization and sound field imaging. Her initial research activities centered on the estimation of source locations and seabed parameters from shallow-water acoustic data via adaptive inversions. Since coming to BYU, she has shifted from underwater sound to studying high-amplitude aero-acoustics, including military aircraft noise. Her current research on the analysis of military jet aircraft noise includes examining near-field propagation effects, equivalent jet noise sources, including wave packets, and inverse methods such as near-field acoustical holography and beamforming. She has recently constructed a broadband, level-based equivalent source model for jet noise that shows promise for noise exposure estimation and environmental noise modeling.
We welcome anyone who wish to attend, and typically serve refreshments ten minutes before the colloquium begins. Speakers generally keep their presentation accessible to undergraduate physics students.
