Extending the Low Frequency Acoustic Centre Concept to Directional Loudspeakers (2023)
Conference Proceeding
Hargreaves, J. (2023). Extending the Low Frequency Acoustic Centre Concept to Directional Loudspeakers.

The Acoustic Centre of a loudspeaker is defined as being the point from which spherical waves appear to radiate. This is useful to know when performing phase, level, or time alignment, for example. For a single driver in a sealed box, it is typically... Read More about Extending the Low Frequency Acoustic Centre Concept to Directional Loudspeakers.

Adventures in High Intensity Acoustic Testing: a Loudspeaker System for Small-Scale Tests (2023)
Conference Proceeding
Hargreaves, J., Hipperson, J., Wong-McSweeney, D., & O'Doherty, N. (2023). Adventures in High Intensity Acoustic Testing: a Loudspeaker System for Small-Scale Tests.

In the space and aerospace industry, there is a need to perform High Intensity Acoustic Testing (HIAT). This aims to recreate in the laboratory, for the purpose of qualification testing, the extreme acoustic environments that designs must survive in...
