Noise is the most persistent physical contaminant in the environment. In this study, noise level and noise propagation were investigated during the working of natural stone cutting–processing machines used in the natural stone workshops. For this purpose, emerged noise was recorded and analyzed while cutting and processing of marble samples in a workshop where side cutting machine (cross-cutting), portable sawing machine and vibratory tumbling machine are used. Noise level maps were prepared by using equivalent noise data obtained from 110 regular points in the natural stone workshop. They were created by building grids using noise propagation variogram models, and plotting contour maps with Surfer version 10.2 software using kriging method. Risky areas were determined using noise propagation maps and also daily noise exposure limit values and working time. For risky areas in which a high level of noise was detected; the working time restriction, use of personal protective equipment or both are required.

根据噪音确定大理石车间的危险区域

噪声是环境中最持久的物理污染物。在这项研究中，研究了在天然石材车间中使用天然石材切割加工机器的过程中的噪声水平和噪声传播。为此，在使用侧面切割机（横切），便携式锯床和振动翻滚机的车间中切割和处理大理石样品时，记录并分析出现的噪声。使用从天然石材加工车间的110个常规点获得的等效噪声数据，准备了噪声级图。它们是通过以下方式创建的：使用噪声传播变异函数模型构建网格，并使用克里格方法使用Surfer 10.2版软件绘制等高线图。使用噪声传播图以及每日噪声暴露极限值和工作时间来确定危险区域。对于检测到高噪声水平的危险区域；需要限制工作时间，使用个人防护设备或同时使用两者。
