Practical methods for predicting low-frequency behavior in enclosed spaces, including Sabine, Eyring, and NRC models applied to modern concert hall design.
Signal structure, propagation loss in seawater, and how cetaceans exploit the SOFAR channel for long-distance acoustic information transfer across ocean basins.
Windowing functions, time-frequency tradeoffs, and practical implementation considerations for real-time acoustic monitoring and machine learning pipelines.
The interplay between player embouchure, bore geometry, and standing wave formation that defines pitch selection and timbral variation in wind instruments.
Engineered subwavelength structures that manipulate sound propagation beyond natural material limits, enabling acoustic cloaking, superlensing, and topological insulation.
