FIELD: medical equipment.SUBSTANCE: invention relates to medical engineering, in particular to the means of automatic evaluation signal phonocardiogram. Apparatus comprises a phonocardiogram interface adapted to receive a phonocardiogram signal captured according to a first set of capturing properties, a processor adapted to analyze the phonocardiogram signal to determine an analysis result for the phonocardiogram signal and a confidence value of the determined analysis result, and a flow control adapted to determine, whether a subsequent capture of the phonocardiogram signal according to a second set of capturing properties is likely to improve an accuracy of the determined analysis result. If applicable the flow control coordinates the subsequent capture of the phonocardiogram signal according to the second set of capturing properties. In a second embodiment of the device user interface is adapted to receive from a user a correction related to the action of data processing, and segmentation and labeling of the collected signal phonocardiogram, and the processor is further configured to generate another set of collected properties to collect subsequent signal phonocardiogram based on the user correction. Mode of action is provided a signal processing apparatus, and computer-readable medium comprising instructions that, when executed by a processor perform a method for its prompt action device.EFFECT: use of the invention allows to improve the reliability of finding signs of disease.15 cl, 9 dwgИзобретение относится к медицинской технике, а именно к средствам автоматической оценки сигнала фонокардиограммы. Устройство обработки сигналов содержит фонокардиограммный интерфейс, данные которого собраны от пациента в соответствии с соответствующим набором собираемых свойств этого сигнала, выбранных из по меньшей мере одного из места прослушивания, информации о том, дышал пациент или задерживал дыхание, информации о том, был ли пациент в покое или выполнял физические упра
