Microbial contamination of musical wind instruments.
Retrospective and prospective studies were used to assess the numbers, types and persistence of microbes that contaminate wind instruments. All previously played instruments (n = 20) harbored viable bacteria as well as mold and/or yeast. Reedinstruments consistently carried higher microbial loads than did flutes or trumpets. Instruments played within the previous three days bore typical mouth f...
متن کاملThe nonlinear physics of musical instruments
Musical instruments are often thought of as linear harmonic systems, and a first-order description of their operation can indeed be given on this basis, once we recognise a few inharmonic exceptions such as drums and bells. A closer examination, however, shows that the reality is very different from this. Sustained-tone instruments, such as violins, flutes and trumpets, have resonators that are...
متن کاملNonlinear acoustic synthesis in augmented musical instruments
This paper discusses nonlinear acoustic synthesis in augmented musical instruments via acoustic transduction. Our work expands previous investigations into acoustic amplitude modulation, offering new prototypes that produce intermodulation in several instrumental contexts. Our results show nonlinear intermodulation distortion can be generated and controlled in electromagnetically driven acousti...
متن کاملAcoustic pulse reflectometry for the measurement of musical wind instruments
The bore profile and input impedance of a musical wind instrument provide valuable information about its acoustical properties. The time domain technique of acoustic pulse reflectometry can be used to measure the input impulse response of a tubular object, such as a wind instrument, from which both its bore profile and input impedance can be calculated. In this thesis, after a discussion of the...
متن کاملNonlinear Oscillations in Sustained Musical Instruments: Models and Control
Many physical models of sustained musical instruments (strings, brass, reeds, flutes and voices) have been proposed by researchers in acoustics and computer music. We focus on an interesting class including a memoryless nonlinearity, a time-delay term and a filtering kernel in the delay line. Stability, oscillation, and other conditions for the dynamic behavior of this class of models are studi...
