The tinnitus and hearing loss treatment equipment integrates multiple functions such as precision audiometry, acoustic therapy, and physical pulse intervention. Addressing the vulnerability of its highly sensitive audio sampling circuit to external electromagnetic pulse (EMP) interference, and the internal crosstalk when multiple treatment modules (acoustic, optical, and electrical) coexist, we provide high common-mode rejection ratio (CMRR) protection and an ultra-low parasitic capacitance interface anti-static solution. These technologies ensure accurate and unbiased hearing test signals while effectively isolating transient pulses generated by physical therapy, guaranteeing efficient coordination of the multimodal treatment process and the long-term reliability of the system.
