9Theoretical analysis about eigenfrequencies of 'aligned double flute显示文摘In this paper, an improved theory for determination of thc eigen-frequen cies of the flute is expounded. The theory is developed from a previous work in order that it can be extended to analyze the flute of a new type, so called 'aligned double flute’. The acoustic character of the double flute is analyzed rigorously. The proce dure to calculate the correction of the effective length of the tube at exit terminal is in vestigated. Theoretical formulae to determinate the eigenfrequencies of the flute are derived. Correction caused by the warm flow are discussed. Two typical structures of the double flute are examined. It is shown that the experimental data are in good agreement with the theorctical results. It shows the present theory is delicate and reli able. It can servc as thc theoretical fundament for design or manufacture of the aligned double flute in practice.ZHAO Songling (Institute of Acoustics, Tongji University.
