Abstract—This paper explores the dynamic world of noise-canceling headphones through active noise control methods and passive noise control methods, as well as integrating active and passive noise control methods, aiming to create a harmonious auditory experience in our increasingly noisy environments. By comparing that method, it is found that with Active Noise Reduction (ANR) excelling at tackling low-frequency disturbances and Passive Noise Reduction (PNR) effectively attenuating high-frequency sounds, the integration of these techniques provides a holistic solution, offering a sanctuary of serenity for individuals. The paper begins with the imperative role of noise reduction, addressing the growing need for auditory comfort in our modern world. A comprehensive literature review traces the historical evolution of noise control techniques, culminating in the integration of ANR and PNR, providing users with a spectrum of noise reduction capabilities. This integrated approach finds practical application in the MRI setting, where patients and healthcare professionals can benefit from a quieter and less anxiety-inducing environment. Furthermore, the discussion delves into the boundless future of this technology, anticipating its applications in aviation, healthcare, and everyday life, reflecting the financial value it holds. This paper also makes a comparative analysis of active noise reduction and passive noise reduction from five dimensions, respectively, effectiveness of active and passive noise control, user experience and comfort, environmental and health considerations, ongoing technological advancement and customization, and market trends, to reflect the development potential of noise reduction technology in the market. The hybrid of ANR and PNR techniques in noise-canceling headphones offers an auditory oasis, meeting the intrinsic human need for tranquillity in a bustling world.
