Equation (2) can be further abbreviated as follows:where, , channel matrix, and noise. To provide more context to Strategic Noise Mapping and to explain some of the technical details, IarnrГіd Г‰ireann has produced two separate explanatory documents ( General InformationВ and FAQs). Yongzhi Yu, Jianming Wang, Limin Guo, Multisegment Mapping. The IarnrГіd Г‰ireann Strategic Noise Maps graphically displays the exposure of the receiving environment to noise generated by train movements along specific sections of the rail network, ie within Agglomeration Areas and/or where the operational rail traffic exceeds 30,000 vehicle passages per annum. Utilization of remote sensing data for a more objective characterization of the persistence of planar discontinuities affecting rock masses is highlighted herein.IarnrГіd Г‰ireannвЂ™s Strategic Noise Maps are provided for public access in accordance with the legislative requirements of the Environmental Noise Regulations 2006. An assessment on the applicability of the method to the 3D point cloud is also presented. Complexities and difficulties related to the method (e.g., natural discontinuity waviness) are reported and discussed. Results presented good agreement with field measurements, validating the methodology. Three case studies are utilized to illustrate the methodology: (1) small-scale laboratory setup consisting of a regular distribution of cubes with similar dimensions, (2) more complex geometry consisting of a real rock mass surface in an excavated cavern and (3) slope with persistent sub-vertical discontinuities. The proposed approach is implemented in a graphic interface with open source software.

Persistence is measured in the directions of the dip and strike for each coplanar set of points, resulting in the extraction of the length of the maximum chord and the area of the convex hull. Coplanar clusters are then merged into a single group of points. SoundandNoise Lecture 10 1 ISE3614IntrotoHumanFactors J. The method proposed herein starts by clustering points that belong to patches of a given discontinuity. View Lecture Slides - 15Sound+and+Noise+2 from ISE 3614 at Virginia Tech. This work presents a methodology for the automatic mapping of discontinuity persistence on rock masses, using 3D point clouds. PDF On May 1, 2016, Enda Murphy and others published Testing the accuracy of smartphones and sound level meter applications for measuring environmental noise Find, read and cite all the. Remote sensing techniques potentially provide new ways of analysing visible data from the rock mass.

Finding new ways to quantify discontinuity persistence values in rock masses in an automatic or semi-automatic manner is a considerable challenge, as an alternative to the use of traditional methods based on measuring patches or traces with tapes.
