Acoustic impedance measurements of wind instruments

Measurements of the acoustic input impedance of wind instruments and their subparts can be useful for analyzing playing aspects, such as intonation, ease of response, and for comparison with numerical models. This talk will start with a discussion of commercial and custom measurement equipment options overviewing their particular features, calibration methods, advantages, disadvantages, and their associated costs. The remainder of the talk will focus on a custom-built, multi-microphone system developed in the Computational Acoustic Modeling Laboratory at McGill University, with a demonstration of its use in measuring one or two wind instruments. The authors are happy to share all hardware and software details of this system with anyone interested.
