===== Woodwind Instruments Design Optimisation =====

**Participants:** Antoine Lefebvre and Gary Scavone

**Period:** 2005 - 2012

----

==== Summary ====

This research was focused on the design of woodwind instruments with improved acoustical and mechanical characteristics, accomplished with the aid of new materials, physical modelling, impedance measurements, and collaborations with professional musicians. It included experiments to characterize the influence of important acoustical parameters in assessing the quality of instruments. The work also involved computer-based design optimisation using the Transfer Matrix Method, which parameters derived from Finite Element Modeling.

The [[wiat:wiat|Wind Instrument Acoustic Toolkit (WIAT)]] is a Python package that was developed in the course of this research.
