This is standardized by the European Standards EN 1793, parts 2 and 6, in which a single parameter, DLR or DLSI, is defined in order to quantify the sound insulation performance of noise barriers. However, the final performance of a noise barrier, quantified by the so-called insertion loss, IL is not only dependent on the insulation provided by the noise barrier, but it is as well affected by geometrical aspects and the acoustic characteristics of the environment where these noise-reducing devices are placed. In this work, we explore the relationship between the insertion loss and the acoustic insulation by means of numerical methods. Moreover, the authors propose a simple way to predict the insertion loss from a purely acoustic numerical simulation in which this parameter is obtained for a completely rigid noise barrier, and knowing the noise barrier\u2019s sound reduction index, in one third octave bands.<\/jats:p>","DOI":"10.3390\/app12147027","type":"journal-article","created":{"date-parts":[[2022,7,12]],"date-time":"2022-07-12T20:52:41Z","timestamp":1657659161000},"page":"7027","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["A Simple Method to Estimate the In Situ Performance of Noise Barriers"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5507-7799","authenticated-orcid":false,"given":"Javier","family":"Redondo","sequence":"first","affiliation":[{"name":"Instituto de Investigaci\u00f3n Para la Gesti\u00f3n Integrada de Zonas Costeras, Universitat Polit\u00e8cnica de Val\u00e8ncia, C\/Paranimf n\u00ba1, 46730 Val\u00e8ncia, Spain"}]},{"given":"Pau","family":"Gaja-Silvestre","sequence":"additional","affiliation":[{"name":"Instituto de Investigaci\u00f3n Para la Gesti\u00f3n Integrada de Zonas Costeras, Universitat Polit\u00e8cnica de Val\u00e8ncia, C\/Paranimf n\u00ba1, 46730 Val\u00e8ncia, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2989-375X","authenticated-orcid":false,"given":"Luis","family":"Godinho","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, University of Coimbra, ISISE, Rua Lu\u00eds Reis Santos, 3030-788 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2233-2383","authenticated-orcid":false,"given":"Paulo","family":"Amado-Mendes","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, University of Coimbra, ISISE, Rua Lu\u00eds Reis Santos, 3030-788 Coimbra, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,12]]},"reference":[{"key":"ref_1","unstructured":"(2012).
