Abstract
The aims of this work were to determine if the exponential distribution can be implemented in order to study the time-frequency behaviour of Korotkoff sounds, and also to identify key features in each of the different phases of the Korotkoff sounds. It was found that, in this evaluation study, the running window exponential distribution time-frequency approach shows promise for studying the time-frequency behaviour of Korotkoff sounds, and also for identifying key features in each of the different phases of the Korotkoff sounds. Further work is now needed to evaluate the technique when applied to a larger number of volunteers, to optimise protocols for Korotkoff sound recording, and to assess different approaches in time-frequency distribution visualization.
