The research assistant will record decibel levels in each location during BP readings using a Reed Sound Level Meter C-322 (Reed Instruments, Ste-Anne-de-Bellevue, Quebec, Canada). The sound level meter includes a data logger, and the mean decibel level per location for each set of readings will be recorded. The assistant will be trained in the use of the sound meter and logger and will use it during the five supervised BP training readings. The research assistant will also measure and record the patient's weight in kg, height in cm, and will collect information on patient's gender and self reported history of hypertension.
