The Syrinx: Nature’s Hybrid Wind Instrument
نویسندگان
چکیده
This research presents a model of the avian vocal tract, implemented using waveguide synthesis and numerical methods. The vocal organ of the songbird, the syrinx, has a unique topography of acoustic tubes (a trachea with a bifurcation at its base) making it a novel subject for waveguide synthesis. In the upper region of the two bifid bronchi lies a nonlinear vibrating membrane—the primary resonator in sound production. The model of the membrane displacement, and the resulting pressure through the constriction created by the membrane motion, is derived based on the Bernoulli equation for the air flow and the mechanical properties of the membrane and surrounding tissue.

Syringes and syringomyelia.
The earliest description of cavities in the cord is generally ascribed to Charles Estienne (1504–c.1564) in La dissection des parties du corps humain... Paris, 1546. But the fi rst use of the term ‘syringomyelia’ was probably that of Charles P. Oliviers d’Anger in De la moelle épinière et ses maladies in 1824; in a later two-volume work he described: ‘Syringomyélie ou cavité centrale dans la mo...
متن کاملDeveloping a hybrid wind instrument: using a loudspeaker to couple a theoretical exciter to a real resonator
331 A hybrid wind instrument generates self-sustained sounds via a real-time interaction between a computed physical model of an exciter (such as human lips interacting with a mouthpiece) and a real acoustic resonator. Successful implementation of a hybrid wind instrument will not only open up new musical possibilities but will also provide a valuable research tool. However, attempts to produce...
متن کاملDevelopment of a mathematical model to design an offshore wind and wave hybrid energy system
Fossil Fuels are always considered as environmental pollutants. On the other hand, the political and economic situations highly affect the price of these fuels. Offshore wind and wave, as renewable energy sources, represent the better alternatives for electricity generation. Therefore, it is necessary that wind speeds effectively be estimated due to the absence of field measurements of the wind...
متن کاملNew perspectives on the physics of birdsong.
In this work, we revisit the path that has been travelled during the last few years towards the modelling of the avian vocal organ, the syrinx, using numerical and theoretical techniques from bifurcation theory as analysing tools and present experimental support for the models. This fruitful perspective allowed the retracing of many acoustic features of syllables to intrinsic properties of the ...
متن کاملCombined Use of Sensitivity Analysis and Hybrid Wavelet-PSO- ANFIS to Improve Dynamic Performance of DFIG-Based Wind Generation
In the past few decades, increasing growth of wind power plants causes different problems for the power quality in the grid. Normal and transient impacts of these units on the power grid clearly indicate the need to improve the quality of the electricity generated by them in the design of such systems. Improving the efficiency of the large-scale wind system is dependent on the control parameter...
