Parts of a Stethoscope
Understand the essential components that make up a stethoscope and how they function.

A stethoscope may appear simple, but its design is a combination of thoughtful acoustics and ergonomic engineering. Whether you're a beginner or an experienced medical professional, knowing each part helps improve both your technique and diagnostic accuracy.

Key Parts of a Stethoscope
Here’s a breakdown of the main components and what they do:
1. Chest Piece
The chest piece is the part placed against the patient’s body. It typically includes two sides:
- Diaphragm – The larger, flat side is used for high-frequency sounds like heartbeats or breath sounds.
- Bell – The smaller, concave side is used for low-frequency sounds like certain heart murmurs.
- Some stethoscopes (like dual-head models) have both diaphragm and bell, while others have a tunable diaphragm that combines both.
Revival Example:
Revival® Dual Head Stethoscope – Features both bell and diaphragm for full-range auscultation.
2. Stem
The stem connects the chest piece to the tubing. It often allows rotation to switch between the diaphragm and bell (in dual-head models).
3. Tubing
This is the flexible rubber or PVC part that transmits sound from the chest piece to the earpieces.
Key features to look for:
- Thicker tubing = better sound insulation
- Latex-free materials for skin safety
- Durability for daily wear and tear
Revival Advantage:
Our tubing is designed for Indian conditions, offering flexibility and long-lasting acoustic performance in high-use environments.
4. Headset
This includes the binaural tubes (metal tubes connecting to the ear tips) and the spring mechanism that holds them together.
- Made of stainless steel or aluminium
- Angled anatomically for proper ear insertion
5. Ear Tips
These soft, snug-fitting tips sit in your ears to deliver sound. High-quality ear tips provide comfort and seal out ambient noise.
Look for:
- Soft silicone or rubber material
- Replaceable designs
- Different sizes for fit customization
Revival Feature:
All our stethoscopes, including the Revival® Acoustic comes with comfortable ear tips designed for long hours of clinical use.
