- 論文の詳細を見る
Study was made on the frequency distribution and the absolute intensity of the chest wall vibration caused by the mechanical action of the heart in order to establish a physical basis for standardization of phonocardiograph and calibration of heart sounds and murmurs. Thereafter, the available results were obtained.
