An experimental setup is proposed and used for the analysis of these vibrations transmitted by the box housing, based on the measurement of the mechanical impedance. It is then shown that a simpler measurement, namely that of the generated noise spectrum, can provide equally useful results, with less effort and in a shorter time. The experimental setup is much simpler, involving a sonometer arranged in the experimental assembly. The symmetry of the box allows us to facilitate the execution of the experimental assembly, and the use of the symmetrical structure to facilitate the calculation of vibrations. The results obtained using this method in the case of a redesigned adder box are presented in the paper.<\/jats:p>","DOI":"10.3390\/sym13112165","type":"journal-article","created":{"date-parts":[[2021,11,11]],"date-time":"2021-11-11T23:07:21Z","timestamp":1636672041000},"page":"2165","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Adder Box Used in the Heavy Trucks Transmission Noise Reduction"],"prefix":"10.3390","volume":"13","author":[{"given":"Andrei","family":"Bencze","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Transilvania University of Bra\u0219ov, B-Dul Eroilor 20, 500036 Bra\u0219ov, Romania"}]},{"given":"Maria Lumini\u021ba","family":"Scutaru","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Transilvania University of Bra\u0219ov, B-Dul Eroilor 20, 500036 Bra\u0219ov, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1552-3763","authenticated-orcid":false,"given":"Marin","family":"Marin","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Transilvania University of Bra\u0219ov, B-Dul Eroilor 20, 500036 Bra\u0219ov, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8679-2579","authenticated-orcid":false,"given":"Sorin","family":"Vlase","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Transilvania University of Bra\u0219ov, B-Dul Eroilor 20, 500036 Bra\u0219ov, Romania"},{"name":"Romanian Academy of Technical Sciences, B-Dul Dacia 26, 030167 Bucharest, Romania"}]},{"given":"Ana","family":"Toderi\u021b\u0103","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Transilvania University of Bra\u0219ov, B-Dul Eroilor 20, 500036 Bra\u0219ov, Romania"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,11]]},"reference":[{"key":"ref_1","first-page":"22","article-title":"Modeling Vibration and Noise in a Gearbox","volume":"140","author":"Soami","year":"2018","journal-title":"Mech.
