摘要：

An analysis of phonothyreograms and phonocardiograms was made with the aid of an ND minicomputer and a CYBER 73 computer system using an ECG signal as a reference time signal. Programs were written to estimate the power spectral density function of these signals. In patients with Graves'' disease and those with nodular goiter the intrinsic thyroid murmur differed from the sound transmitted from the heart in healthy subjects by a large contribution of frequencies in the 250-750 Hz range, this factor being particularly pronounced in patients with Graves'' disease.
