A key technology behind the functioning of our stethoscope is the audio waveguide embedded into the bell of our device. A waveguide is defined as a physical structure for guiding sound waves.
Steth IO’s waveguide is a patented piece of technology allowing us to filter out many irrelevant sounds while amplifying heart and lung sounds.
The waveguide feeds captured sound directly into iPhone’s sensitive microphone. The waveguide’s design also ensures that biological sounds are captured at very high fidelity and do not dissipate before detection.
