A smarter way to tame tinny bone-conduction audio

Key Points

• The study aims to enhance sound quality in piezoelectric bone-conduction devices using a special fluid.
• Utilized a cornstarch-like fluid for selective damping of vibrations.
• Analyzed the frequency response of bone-conduction audio before and after fluid application.
• Evaluated sound clarity improvements in piezoelectric devices.
• Flattened frequency response was achieved with the introduction of the damping fluid.
• Notable reduction in harsh vibrations was observed.
• Users experienced clearer sound in piezoelectric bone-conduction devices.
