1) The product is used for listening to the sound changes in the activities of the heart, lungs, and organs in the human body;

The stethoscope is used to detect vital signs such as heart rate and blood pressure;

The principle of a stethoscope is that vibration transmission between substances contributes to the aluminum membrane within the stethoscope, rather than air. This changes the frequency and wavelength of sound, reaching a range that is "comfortable" for the human ear, while also masking other sounds, allowing for clearer hearing. The reason people can hear sounds is that what we call "sound" is caused by the mutual vibration transmission between substances, such as air vibrating the eardrum in the ear, which is then converted into brain electricity, enabling us to "hear" the sound. The vibration frequencies that the human ear can perceive range from 20–20 KHZ.
Another standard for human perception of sound is volume, which is related to wavelength. The intensity range for normal hearing is 0 dB to 140 dB.
