AbstractThe Computational Acoustical Modeling Laboratory (CAML) of the Music Technology area, Schulich School of Music, McGill University, studied an understanding of the fundamental wind acoustic behavior of music instruments and other sounding objects. The two-microphone transfer function method recorded signals at microphone pairs placed along the tube estimated the instrument input impedance. Pulse reflectometry makes use of a long tube with a single microphone to measure impulse response and system reflectance. Web-based interface allows evaluation of the input impedance of saxophones in terms of cylindrical and conical segments and toneholes. The wind acoustic measurement approach assumes continuity of volume flow on either side of the reed, which leads to a direct proportionality between the upstream and downstream pressures and impedances.
