![]() The lung sound monitoring device as claimed in claim 2, wherein after outputting the movement instruction signal and moving the lung sound monitoring device to the second monitoring position on the subject, the acoustic sensor captures the chest cavity sound of the subject at the second monitoring position and converts the chest cavity sound into a second chest cavity sound signal ![]() ![]() The lung sound monitoring device as claimed in claim 1, wherein the processor generates the prompt signal according to whether the first intensity index exceeds a threshold when the first intensity index does not exceed the threshold, the prompt signal is a movement instruction signal to indicate that the lung sound monitoring device needs to be moved to a second monitoring position on the subject when the first intensity index exceeds the threshold, the prompt signal is a positioning-completion signal, and the lung sound monitoring device starts to record the lung sound of the subject.ģ. A lung sound monitoring device, comprising:Īn acoustic sensor, for capturing a chest cavity sound of a subject at a first monitoring position on the subject and converting the chest cavity sound into a first chest cavity sound signal and a processor, for receiving the first chest cavity sound signal and performing a filter process to obtain a first lung sound signal, and converting the first lung sound signal into a first lung sound spectrum using time-domain frequency-domain conversion wherein the processor acquires a first intensity index according to the first lung sound spectrum, and outputs a prompt signal according to the first intensity index to indicate whether the first monitoring position is a qualified monitoring position.Ģ.
