Origin of the Sound Components During Pharyngeal Swallowing in Normal Subjects

  title={Origin of the Sound Components During Pharyngeal Swallowing in Normal Subjects},
  author={Sylvain Morini{\`e}re and Michele Boiron and Daniel Alison and Pascal Makris and Patrice Beutter},
The aim of this study was to identify the origin of swallowing sound components by using modern techniques that can provide numeric, synchronized acoustic–radiologic data. We enrolled 15 volunteer subjects (10 men and 5 women, average age = 29.5 ± 8 years) and used an X-ray camera connected to a video acquisition card to obtain synchronized acoustic–radiologic data (25 images/s). The subjects were asked to swallow 10 ml of a barium suspension. Each sound component was associated with a specific… CONTINUE READING
