True Stereo Auscultation Technology
Stereophonet No.171 GOLD employs a fully independent left–right sound collection and transmission system, enabling clinicians to perceive sound with unprecedented spatial detail.
• The chestpiece is divided into left and right chambers by a central partition
• Each chamber connects to an independent TWO-IN-ONE tube
• Sound collected on the right side is transmitted to the right ear, and sound from the left side to the left ear
This structure allows clinicians to detect important laterality information that is often lost with conventional stethoscopes.

• To-and-fro murmurs in aortic valve disease are heard with vivid realism
Prosthetic Valve Sounds

Normal Heart Sounds
• First (Ⅰ) and second (Ⅱ) heart sounds are perceived as localized, point-source sounds without spatial spread
