Project 1: Recent decades have seen great advances in our understanding of human audition. When presented with two pure tones of close but distinct frequencies, we perceive the sound as either a single pitch with amplitude variation (beats) or as two tones forming a musical interval. This project will investigate the link between this audition process and some of the subjective aspects of music such as choice of scale, mode, the relationship of major and minor chords and the correspondence of rhythm and harmony.
Project 2: This project will investigate the effect of a practice mute on the acoustic properties of a French horn by looking at the input acoustic impedance with and without a mute inserted in the bell. Measurements made at the Acoustics Laboratory at the University of New South Wales will be analysed and equivalent complex impedances fitted to the data.
