Abstract

Abstract The increasing human population and the increasing number of vehicles in Tirana, Albania, emerges the need for extensive measurements of noise levels. The 831 measurements of noise levels were taken in Tirana in November 2015 for education purposes. Measurements were collected in eight locations in indoor like a classroom in a school building environment, a library and a healthcare facility and in outdoor environments like five crossroads. Noise levels were then compared with domestic and World Health Organization (WHO) standards. The logarithmic average of noise levels and the maximum value of noise level measured for the period of measurement (LAFmax) were interpolated using Interpolated Noise Levels for Observer Points in ArcGIS producing noise level maps for crossroads. The logarithmic average of noise levels and LAFmax measurements were respectively above domestic and WHO standards in 96% and 100% of outdoor environment and indoor environment locations. Interpolated values of logarithmic average of noise levels and LAFmax for five crossroads were above domestic and WHO standards indicating noise levels in road traffic could remain high. A yearly acoustic measurement for vehicles should be implemented. Participatory measurements of noise levels in quite indoor environments can be used to increase the awareness of inhabitants in Tirana.

对不断扩大的城市地区室内外环境噪声水平测量的结果:以地拉那为例

摘要阿尔巴尼亚地拉那的人口不断增加，车辆数量不断增加，因此需要对噪音水平进行广泛的测量。2015年11月在地拉那进行了831次噪音水平测量，用于教育目的。测量是在室内的八个位置收集的，如学校建筑环境中的教室、图书馆和医疗机构，以及在室外环境中的五个十字路口。然后将噪音水平与国内和世界卫生组织（世界卫生组织）的标准进行比较。使用ArcGIS中观察点的插值噪声水平对噪声水平的对数平均值和测量期间测量的噪声水平的最大值（LAFmax）进行插值，生成十字路口的噪声水平图。在96%和100%的室外环境和室内环境位置，噪声水平的对数平均值和LAFmax测量值分别高于国内和世界卫生组织标准。五个十字路口的噪声水平对数平均值和LAFmax的插值值高于国内和世界卫生组织标准，表明道路交通中的噪声水平可能仍然很高。应每年对车辆进行声学测量。参与式测量室内环境中的噪音水平可以用来提高地拉那居民的意识。

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.
