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 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 کاملDiscrete-time modelling of musical instruments
This article describes physical modelling techniques that can be used for simulating musical instruments. The methods are closely related to digital signal processing. They discretize the system with respect to time, because the aim is to run the simulation using a computer. The physics-based modelling methods can be classified as mass–spring, modal, wave digital, finite difference, digital wav...
متن کاملA Bond Graphs approach to Physical Modelling of Musical Instruments
In this paper we introduce the use of bond graphs for the implementation of classic physical models of musical instruments. Bond graphs are a diagram-based technique for representing physical systems, such as an electrical circuit or a mechanical engine. They provide a precise and unambiguous modelling tool which allows for the specification of hierarchical physical structures. The paper begins...
متن کاملA single microphone capillary-based system for measuring the complex input impedance of musical wind instruments
Capillary-based systems for measuring the input impedance of musical wind instruments were first developed in the mid-20th century and remain in widespread use today. In this paper, the basic principles and assumptions underpinning the design of such systems are examined. Inexpensive modifications to a capillary-based impedance measurement set-up made possible due to advances in computing and d...
