Respiratory acoustic measurements have shown promise in investigation of upper airway disorders in man and, more recently, in horses with experimentally\u2010induced obstructions.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Objectives<\/jats:italic>\n                    : To evaluate sounds from exercising horses with naturally occurring dynamic obstructions of the upper respiratory tract and to compare these with those from normal horses in order to determine whether different obstructions produce characteristic spectral patterns.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Methods<\/jats:italic>\n                    : The audio signal, airflow and videoendoscopic images were recorded simultaneously during an incremental exercise test on a high\u2010speed treadmill.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Results<\/jats:italic>\n                    : Spectral analysis of the audio signal showed marked differences between control and clinically afflicted horses. Dorsal displacement of the soft palate was characterised by a narrow low frequency (20\u201380 Hz) peak during expiration.
