Cochlear implant systems are used in diverse environments and should function during work, exercise and play as people go about their daily lives. This is a demanding requirement, with exposure to liquid and other contaminant ingress from many sources. For reliability, it is desirable that the speech processor withstands these exposures. This design challenge has been addressed in the Nucleus(R) Freedom(TM) speech processor. The Nucleus Freedom speech processor complies with International Standard IEC 60529, as independently certified. Tests include spraying the processor with water followed by immediate verification of functionality including microphone response, radio frequency link and processor controls. The processor has met level IP44 of the Standard.
人工耳蜗系统应用于各种不同环境，并且在人们日常生活、工作、锻炼及娱乐时都应能正常运行。这是一项严苛的要求，因为会接触到来自多种源头的液体和其他污染物侵入。为确保可靠性，希望言语处理器能经受住这些接触。Nucleus Freedom™言语处理器解决了这一设计难题。Nucleus Freedom言语处理器已通过独立认证，符合国际标准IEC 60529。测试包括向处理器喷水，随后立即验证其功能，包括麦克风响应、射频链接和处理器控制。该处理器已达到标准的IP44防护等级。
