Murray Campbell studied physics at the University of Edinburgh (Edinburgh, Scotland). He was appointed to the teaching staff there in 1971, and in 1985, he founded the University’s Musical Acoustics Research Group. He is now professor emeritus and senior professorial fellow at the University of Edinburgh, where he continues to carry out research on the acoustics of lip-excited wind instru- ments. He is a Fellow of the Acoustical Society of America and in 2019 was awarded the ASA Silver Medal in Musical Acoustics. He has coauthored three textbooks on musi- cal acoustics, including The Science of Brass Instruments (Springer, 2021).

Joël Gilbert is Directeur de Recherche CNRS in and a former head of the Acoustic Laboratory of Le Mans University (Le Mans, France). He read physics and acoustics at the École Normale Supérieure (ENS) of Fontenay-aux-Roses and at Le Mans University. He received a doctorate from Le Mans University for investigating the acoustics of reed musical instruments. He currently researches nonlinear acoustical systems, nonlinear acoustic propagation, and nonlinear dynamics of self-sustained oscillators, with application
existing designs of a mute but will also provide brass players with exciting new possibilities for shaping the sounds that emerge from their musical horns.
