Adult Dual Head Stethoscope (Dual-Sided Stethoscope)

1) The product is used to listen to the sounds of the heart, lungs, and organs to detect changes in their activity.

The stethoscope is used to detect heart rate, blood pressure, and other vital signs.

The principle of a stethoscope is that the vibration transmission between materials is involved in the aluminum membrane of the stethoscope, not just air, which changes the frequency and wavelength of the sound, bringing it within the "comfortable" range for the human ear, while also masking other sounds, allowing for a clearer "hearing." The reason humans hear sounds is that so-called "sound" is the vibration transmission between materials, such as air vibrating the eardrum in the ear, which is then converted into brain currents, allowing humans to "hear" the sound. The vibration frequency that the human ear can perceive ranges from 20 to 20 kHz.
