Abstract	Noise in operation theatres (OTs) is a major environmental and occupational concern, affecting both surgical performance and patient safety. Studies report that noise levels in OTs often exceed recommended limits of 35–40 dBA set by national (NBC, NABH) and international (ASHRAE, WHO) standards, sometimes reaching 80–120 dBA during active procedures. This research explores soundproofing materials and architectural design strategies used to reduce noise through an engineering approach. A review of recent studies (2021–2025) highlights the use of high-STC partition walls, cleanable acoustic ceilings (NRC ≥ 0.7), double-glazed windows, and vibration-isolated HVAC systems as effective technical measures. The findings emphasize that both behavioral and structural interventions are essential—strategic layout planning, staff education, noise monitoring, and low-noise equipment all contribute to sustainable reduction. The integration of acoustically optimized materials with hygienic and compliant design not only reduces decibel levels but also improves staff concentration, communication, and clinical outcomes. Therefore, adopting evidence-based acoustic strategies from the early planning stages is crucial for creating quieter, safer, and more efficient operation theatres.
