Environmental noise has been growing in recent years, causing numerous health problems. Highly sensitive environments such as hospitals deserve special attention, since noise can aggravate patients' health issues and impair the performance of healthcare professionals. This work consists of a systematic review of scientific articles describing environmental noise measurements taken in hospitals between the years 2015 and 2020. The researchers started with a consultation of three databases, namely, Scopus, Web of Science, and ScienceDirect. The results indicate that for the most part, these studies are published in journals in the fields of medicine, engineering, environmental sciences, acoustics, and nursing and that most of their authors work in the fields of architecture, engineering, medicine, and nursing. These studies, which are concentrated in Europe, the Americas, and Asia, use as reference values sound levels recommended by the World Health Organization. L measured in hospital environments showed daytime values ranging from 37 to 88.6 dB (A) and nighttime values of 38.7 to 68.8 dB (A). L values for outdoor noise were 74.3 and 56.6 dB (A) for daytime and nighttime, respectively. The measurements were taken mainly inside hospitals, prioritizing more sensitive departments such as intensive care units. There is a potential for growth in work carried out in this area, but research should also include discussions about guidelines for improvement measures aimed at reducing noise in hospitals.
近年来，环境噪声不断增长，导致了许多健康问题。医院等高度敏感的环境需要特别关注，因为噪声会加重患者的健康问题，并影响医护人员的工作表现。本工作对 2015 年至 2020 年间在医院进行的环境噪声测量的科学文章进行了系统回顾。研究人员首先查阅了 Scopus、Web of Science 和 ScienceDirect 这三个数据库。结果表明，这些研究大多发表在医学、工程、环境科学、声学和护理领域的期刊上，其作者大多来自建筑、工程、医学和护理领域。这些主要集中在欧洲、美洲和亚洲的研究以世界卫生组织推荐的声级作为参考值。在医院环境中测量的 L 值显示，白天的数值范围为 37 至 88.6 dB（A），夜间的数值为 38.7 至 68.8 dB（A）。室外噪声的 L 值分别为 74.3 和 56.6 dB（A），用于白天和夜间。测量主要在医院内部进行，重点是重症监护室等更敏感的部门。该领域的工作有增长的潜力，但研究还应包括关于改善措施指南的讨论，以减少医院的噪声。
