    • Modeling pulse-like lip vibrations in brass instruments 

      Kemp, Jonathan A; Smith, Richard (Acoustical Society of America, 2013-06-02) - Conference item
      During the starting transient of a note on a brass instrument it can take several cycles of lip vibration before acoustics reflections from the end of the instrument can influence the lip frequency. Under certain conditions ...
    • The soft-source impedance of the lip-reed : experimental measurements with an artificial mouth 

      Harrison, Reginald; Kemp, Jonathan A; Newton, Michael (Acoustical Society of America, 2013-06-02) - Conference item
      Most theoretical descriptions of the brass instrument lip-reed consider the acoustical condition at the lips to be a closed, rigid termination, corresponding to a unitary reflectance. This assumption is carried through to ...
    • Time domain wave separation using multiple microphones 

      Kemp, Jonathan A; van Walstijn, Maarten; Campbell, Murray; Chick, John; Smith, Richard (2010-07) - Journal article
      Methods of measuring the acoustic behavior of tubular systems can be broadly characterized as steady state measurements, where the measured signals are analyzed in terms of infinite duration sinusoids, and reflectometry ...
    • Wave separation in the trumpet under playing conditions and comparison with time domain finite difference simulation 

      Kemp, Jonathan A; Bilbao, Stefan; McMaster, James; Smith, Richard (2013-08) - Journal article
      Wave separation within a trumpet is presented using three high pressure microphones to measure pressure waves within the curved, constant cross-section tuning slide of the instrument while the instrument was being played ...
