Abstract

Abstract The present study is intended to get to know the levels of perimeter diurnal environmental noise of four hospitals in the city of Lima. The measurement mode used at each hospital was A-weighting, with an integration time of five minutes per recording. It was measured in the FAST mode with calibrations made at the beginning and end of the measurement day. Statistical analysis consisted of the mean comparison T test which was applied at all the hospitals considered in the study. At the four hospitals, at all the hours of measurement and both on working days and non-working days (Sunday), LAeq mean values are higher than 83 dBA. On working days, two periods of maximum noise from 08:00 to 10:00 in the morning and from 17:00 to 19:00 in the afternoon coincide with the start and end of working hours. The perimeter diurnal environmental noise levels determined at the vicinity of four hospitals show higher values in all cases to those established by the Peruvian National Environmental Standards for Noise for special protection areas both for working days and for non-working days. Noise that comes from the dense and disorganized traffic of Lima plays a fundamental role in this behaviour.

秘鲁利马市四家医院附近的日间周边环境噪声

摘要本研究旨在了解利马市四家医院周边昼夜环境噪声水平。每家医院使用的测量模式为A加权，每次记录的积分时间为5分钟。在FAST模式下进行测量，并在测量日开始和结束时进行校准。统计分析包括平均比较T检验，该检验适用于研究中考虑的所有医院。在四家医院，在所有测量时间以及工作日和非工作日（周日），LAeq平均值均高于83 dBA。在工作日，上午08:00至10:00和下午17:00至19:00这两个最大噪音时段与工作时间的开始和结束相吻合。在所有情况下，在四家医院附近确定的周边昼夜环境噪声水平均高于秘鲁国家噪声环境标准为特殊保护区制定的工作日和非工作日环境噪声水平。利马密集而无序的交通产生的噪音在这种行为中起着根本作用。

期刊介绍： Ever since its inception, Noise Mapping has been offering fast and comprehensive peer-review, while featuring prominent researchers among its Advisory Board. As a result, the journal is set to acquire a growing reputation as the main publication in the field of noise mapping, thus leading to a significant Impact Factor. The journal aims to promote and disseminate knowledge on noise mapping through the publication of high quality peer-reviewed papers focusing on the following aspects: noise mapping and noise action plans: case studies; models and algorithms for source characterization and outdoor sound propagation: proposals, applications, comparisons, round robin tests; local, national and international policies and good practices for noise mapping, planning, management and control; evaluation of noise mitigation actions; evaluation of environmental noise exposure; actions and communications to increase public awareness of environmental noise issues; outdoor soundscape studies and mapping; classification, evaluation and preservation of quiet areas.
