Proposed aeroacoustic mechanisms of USV production in the rat and mouse larynx. A Dice microCT scan of the rat larynx with cross-sections in medial sagittal plane (middle), and transversal plane parallel to the vocal folds (right). Scale bars, 1 mm. B Schematic of wall impingent (left), alar edge (middle), and shallow cavity (right) aerodynamic mechanisms of USV production in rats. The models are distinct in their local flow conditions (top row, black lines), feedback mechanism (red) and model parameters (bottom row) with jet impingement length x, jet exit speed u, and tracheal flow V (see the “Methods” section).
