Abstract

Alas for phonocardiography, now relegated to memories of its glorious past. Its apparatus is now largely and ignominiously gathering dust in out-of-the-way corners.

This gloomy scenario, although common, is not always followed, fortunately, since a proper appreciation of the role of phonocardiography can teach so much about the art of auscultation and the meaning of heart sounds. It is therefore refreshing to have available Dr Paul B. Stein's monograph on the physical and physiological fundamentals of so much that is taken for granted in auscultation and the basis for which is so often poorly understood.

The volume details a series of elegant experiments painstakingly undertaken by the author and his colleagues over the last decade and longer. All the studies have already been published in appropriate journals, and it is useful to have the series collected in one volume. Emphasis is placed on the factors responsible for creating the second
