Stethoscope Specifications

The stethoscope is an acoustic medical device for auscultation of sound changes in the human heart, lungs, veins, and other organs. When the diaphragm is placed on the patient, body sounds vibrate the diaphragm, creating acoustic pressure waves that travel up the tubing to the listener's ear.

1. Main Materials

• Copper
• Rubber tube
• Spring

2. Acoustic Performance

• Frequency Response:

3. Mechanical Properties

• Spring Hardness: HR15N 82.90–88.40
• Earplug Elasticity (at 140 mm opening): 1.372–1.960 N
• Earplug Elastic Recovery: When pulled to 300 mm and released for 1 minute, permanent deformation ≤ 10 mm.
