R&D spotlight on better acoustics in stethoscopes


Suppliers are using better materials, structures and technologies to make models more efficient, versatile and user-friendly.



  • Enhanced auscultation: China companies are adopting stainless steel chestpieces in more releases to achieve better acoustic quality. New models also employ structures that can filter ambient noise and enhance sound transmission.
  • Ergonomics: To make designs more user-friendly, suppliers are utilizing silicone ear tips in the latest releases. Compared with conventional PVC types, the former is softer and more comfortable. Silicone ear tips also offer better sealing and heat stability, improving the instrument’s efficiency and extend its life span.
  • Electronic versions: A few manufacturers are offering electronic stethoscopes, which generally deliver higher output volume and more functions than conventional designs. Certain releases combine an ECG monitor and a pulse oximeter. Some allow ECG data recording that is transferrable to a computer.
  • Price projection: Many suppliers intend to keep quotes stable in the months ahead despite rising outlay by streamlining production.
