However, this method is subjective and requires sufficient training. In addition, identification of the 5 respiratory sounds specified by the International Lung Sounds Association is difficult because their frequencies overlap: The frequency of normal respiratory sound is 100 to 1000 Hz, wheeze is 100 to 5000 Hz, rhonchus is 150 Hz, coarse crackle is 350 Hz, and fine crackle is 650 Hz (1, 2).Objective: To develop a computer-assisted stethoscope to quickly and accurately identify respiratory sounds.Methods and Findings: We developed a stethoscope that ...References1.
