The original heart sound signal is usually accompanied by interference from respiratory sounds, gastrointestinal sounds and environmental noise. Multi-channel systems need to implement adaptive filtering independently for each channel.
From microphone selection to the application of intelligent algorithms, each step is specifically optimized for the unique characteristics of infant voices, ultimately forming a highly sensitive and low-interference audio monitoring system.
During the research and development phase, oscilloscopes and spectrum analyzers are needed to comprehensively evaluate the signal quality under low power conditions.
Auscultation plays an irreplaceable role in many aspects of clinical diagnosis and treatment. From heart rhythms to lung sounds and bowel sounds, these subtle yet crucial sounds often contain important early clues to diseases.
While running, cycling, hiking, swimming, or even showering, people increasingly want their music or calls to be with them. However, sweat, rain, pool water, and even accidental splashes pose serious challenges to electronic devices.
In daily infant care, a parent's greatest concern is not being able to see their child constantly. Even if they're only briefly leaving the room to prepare a bottle or sort out clothes, a sense of unease inevitably arises when they can't hear anything.
