Rock drilling systems have extensive use in many industries including mining, construction, and oil and water extraction. The process of drilling inevitably creates some noise at the drill-rock collision surface. Loud noises cause serious safety issues in the workplace. Noise level can also be a good indicator of the performance of the drilling tool. This study measured and compared the noise levels created in the drilling environment during the drilling of three types of hard rock, namely Khoshtinat, white Natanz and Nehbandan granites with three types of drill bit with tungsten carbide, Diamond-DLC, and Titanium-Aluminum-Silicon coatings. The software SPSS was used to develop several multivariate linear and nonlinear statistical models for predicting noise level. The results showed that as the mechanical parameters of the drilled rock increased, so did the noise level. Also, in all specimens, as the hardness of the drill bit increased, the noise level generated by drilling decreased. The results of statistical tests showed, at above 90% confidence level, that the developed models can provide reasonably accurate predictions of the noise level to be generated in drilling environments based on the mechanical properties of the drilled rock, the hardness of the drill bit, and operating specifications.

凿岩系统已广泛用于许多行业，包括采矿，建筑以及石油和水的开采。钻削过程不可避免地在钻石碰撞表面上产生一些噪音。大声的噪音会在工作场所造成严重的安全问题。噪声水平也可以很好地指示钻孔工具的性能。这项研究测量并比较了在钻探三种类型的硬岩（即Khoshtinat，白色Natanz和Nehbandan花岗岩）中使用三种类型的碳化钨，金刚石-DLC和钛-铝-硬质合金钻头时在钻探环境中产生的噪音水平。硅涂层。SPSS软件用于开发多个用于预测噪声水平的多元线性和非线性统计模型。结果表明，随着岩石力学参数的增加，噪音水平也是如此。另外，在所有样品中，随着钻头硬度的增加，钻孔产生的噪音水平降低。统计测试的结果表明，置信水平高于90％时，开发的模型可以根据钻探岩石的机械特性，钻头的硬度，在钻进环境中产生的噪声水平提供合理准确的预测。和操作规范。
