Noise is omnipresent in biomedical systems and signals. Conventional views assume that its presence is detrimental to systems' performance and accuracy. Hence, various analytic approaches and instrumentation have been designed to remove noise. On the contrary, recent contributions have shown that noise can play a beneficial role in biomedical systems. The results of this literature review indicate that noise is an essential part of biomedical systems and often plays a fundamental role in the performance of these systems. Furthermore, in preliminary work, noise has demonstrated therapeutic potential to alleviate the effects of various diseases. Further research into the role of noise and its applications in medicine is likely to lead to novel approaches to the treatment of diseases and prevention of disability.
噪声存在于生物医学系统和信号中。传统观点认为，噪声的存在会对系统的性能和准确性造成损害。因此，人们设计了各种分析方法和仪器来去除噪声。然而，最近的研究表明，噪声在生物医学系统中可能发挥有益的作用。本文的综述结果表明，噪声是生物医学系统的一个重要组成部分，通常在系统的性能中起着基础性的作用。此外，在初步研究中，噪声已经表现出治疗各种疾病的潜力，可以减轻这些疾病的影响。进一步研究噪声的作用及其在医学中的应用，可能会为疾病的治疗和残疾的预防带来新的方法。
