Motor control of sound frequency in birdsong involves the interaction between air sac pressure and labial tension
Frequency modulation is a salient acoustic feature of birdsong. Its control is usually attributed to the activity of syringeal muscles, which affect the tension of the labia responsible for sound production. We use experimental and theoretical tools to test the hypothesis that for birds producing to...

Its control is usually attributed to the activity of syringeal muscles, which affect the tension of the labia responsible for sound production. We use experimental and theoretical tools to test the hypothesis that for birds producing tonal sounds such as domestic canaries (Serinus canaria), frequency modulation is determined by both the syringeal tension and the air sac pressure. For different models, we describe the structure of the isofrequency curves, which are sets of parameters leading to sounds presenting the same fundamental frequencies. We show how their shapes determine the relative roles of syringeal tension and air sac pressure in frequency modulation. Finally, we report experiments that allow us to unveil the features of the isofrequency curves. © 2014 American Physical Society. 2014 https://bibliotecadigital.exactas.uba.ar/collection/paper/document/paper_15393755_v89_n3_p_Alonso http://hdl.handle.net/20.500.12110/paper_15393755_v89_n3_p_Alonso |
