The mechanism of the genesis of the Korotkoff soun?ds is investigated by modelexperiment using latex tubes and a segment of iso1atecl[ blood vessel of dogs. Thetube compliance is much reduced when the transmural (internal minus external)pressure is very high or very low, and increases radically for intermediate states.It can be concluded that there are two different mechaxxisms by which the soundsare emitted. One is durable sounds caused by self-excited vibration in the processof collapse of the tube, and the other is impulsive sounds emitted transiently whenthe tube compliance is abruptly decreased. Itis possible to explain qualitatively thechange of sound phases over a wide range from systole to diastole as an ap-propriate mixture of durable and impulsive sounds.
