Abstract
A device for calculating a subject's cardiac pulse transit or arrival time information is configured to receive an electronic audio signal with information indicative of a human voice signal and a primary cardiac pulse signal; generate a power spectral profile of a section of the electronic audio signal, and detect a fundamental frequency (F) of the generated power spectral profile; generate a denoised audio signal; generate a time-domain intermediate signal that captures frequency, amplitude and/or phase of the denoised audio signal; detect at least one intermediate signal fiducial point, within a human cardiac band, in the intermediate signal; detect at least one primary cardiac pulse fiducial point, within a human cardiac band, in the primary cardiac pulse signal; calculate pulse transit time or pulse arrival time information between the at least one detected primary cardiac signal fiducial point and the at least one detected intermediate signal fiducial point.
