How to choosing a better stethoscope

How can know if you're choosing a better stethoscope

Listening to the real sounds

How much did you hear? You can use a stethoscope and listening to your heart. How much is the heartbeat? And why do different brands of stethoscopes get different sounds? It mainly depends on three aspects: 1. The matching precision of head main part 1 and matel bar2’s size. High-precision matching will reduce the size of the gap, thus reducing the sound leakage. 2. Fitting degree of earplugs, we recommend silica gel earplugs because they are softer and less deformable, which can better fit different cochlear sizes. And resistant to alcohol and other disinfection liquid cleaning, increase the service life. 3. Diaphragm quality, glass fiber diaphragm material has better elasticity, better amplification of sound.
