Dual-TubingDual-tubing stethoscopes provide sounds of the heart using two separate sound tubes, each serving individual ears. With this format, it is believed better sound quality is achieved, which means improved diagnostics for patients and health professionals. This is compared to the single lumen design, which carries sound down a single pathway. This design can be found with many different styles of stethoscope and its attributes are important for accurately reading the heart whatever the context.
