Stethoscope Design Features Eartips 

The eartip is critical to the optimal performance of a stethoscope. 

It’s designed to conform to the outer ear canal to seal out extraneous sound. 

Prestige Medical includes soft PVC eartips with all stethoscopes to enhance their performance and comfort. 

Tubing Stethoscope tubing is designed to transfer acoustic sound waves channeled by the stethoscope’s diaphragm and bell to the practitioner during auscultation. 

The thickness of the tube is an important factor in enhancing the efficiency of sound transference. 

Thicker stethoscope tubing transfers sound waves more efficiently while minimizing acoustic interference from the ambient environment. 

Most Prestige Medical stethoscopes incorporate thick walled tubing to help deliver optimal performance. 

Metal There are three metals from which most Prestige Medical stethoscopes are constructed. 

Stainless steel is an alloy prized for its durability and resistance to corrosion, rust, and staining. 

It is also an excellent metal for the transference of sound waves. 

Aluminum is very light weight and economical and that lends a significant functionality benefit to those who prefer the convenience of a lighter weight instrument. 

Zinc is excellent for manufacturing complex stethoscope parts economically such as the Sprague-Rappaport chestpiece while still providing very good acoustic characteristics.
