The method, which makes use of graph theory, funicular polygons and Fresnel ellipsoids, proposes a novel approach by which only the relevant obstacles and paths of the scenario under study are considered, therefore simultaneously providing fast and accurate prediction of sound attenuation. The obstacles can be modeled either as knife edges, wedges, wide barriers or cylinders, with some other polygonal diffracting elements, such as doubly inclined, T- or Y-shaped barriers, also considered. In view of the obtained results, this method shows good agreement with previously published formulations and measurements whilst offering better computational efficiency, thus allowing for the consideration of a large number of obstacles.<\/jats:p>","DOI":"10.3390\/sym12040654","type":"journal-article","created":{"date-parts":[[2020,4,22]],"date-time":"2020-04-22T04:15:13Z","timestamp":1587528913000},"page":"654","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["A Fast UTD-Based Method for the Analysis of Multiple Acoustic Diffraction over a Series of Obstacles with Arbitrary Modeling, Height and Spacing"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3240-2568","authenticated-orcid":false,"given":"Domingo","family":"Pardo-Quiles","sequence":"first","affiliation":[{"name":"Departamento de Tecnolog\u00edas de la Informaci\u00f3n y las Comunicaciones, Universidad Polit\u00e9cnica de Cartagena, E30202 Cartagena, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3298-6439","authenticated-orcid":false,"given":"Jos\u00e9-V\u00edctor","family":"Rodr\u00edguez","sequence":"additional","affiliation":[{"name":"Departamento de Tecnolog\u00edas de la Informaci\u00f3n y las Comunicaciones, Universidad Polit\u00e9cnica de Cartagena, E30202 Cartagena, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"195","DOI":"10.1016\/0022-460X(80)90689-6","article-title":"Diffraction of sound around barriers: Use of the boundary elements technique","volume":"73","author":"Seznec","year":"1980","journal-title":"J.
