conferência - Sociedade Portuguesa de Acústica
Computers combined with acoustic sensors now make it possible to measure various properties of musical instruments at low cost. This talk examines the functioning of brass instruments like the trumpet from the viewpoints of the acoustical engineer, the performer, and the instrument maker. The engineer can take an instrument and measure its acoustic input impedance and impulse response as well as the tones produced when it is played. The performer can evaluate the effects of changes in the construction of the instrument to help the maker improve it. Topics covered include the mathematical modelling of these instruments and what is known about how variations in the construction of an instrument affect its playing characteristics.

Among other projects, he worked on the NASA space program in the 1960s, on the joint US/UK Sonar Research Program in the 1970s, and on the ArpaNet (the ancestor of today’s InterNet) in the 1980s. At the end of 1994 he helped start the S. E. Shires Co., manufacturers of professional trombones and trumpets.
