One of the most commonly used method is Laser Doppler Vibrometry (LDV). However, under the rapid fluctuations of temperature, structural resonances are shifted into the other frequencies. In such situation LDV method may be inconvenient, due to the scanning time. In this paper the authors proposed Chladni figures to modal analysis of the double-panel structure, excited by the loudspeaker enclosed inside the casing with a rigid frame. Double-panel structure has been proven to be particularly useful for noise and vibration reduction applications. Vision images, obtained during the experiments are converted to binary patterns, using GLCM matrix, and compared with simulations performed in ANSYS.<\/jats:p>","DOI":"10.3390\/s20154084","type":"journal-article","created":{"date-parts":[[2020,7,23]],"date-time":"2020-07-23T11:26:01Z","timestamp":1595503561000},"page":"4084","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Chladni Figures in Modal Analysis of a Double-Panel Structure"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2629-2286","authenticated-orcid":false,"given":"Jaroslaw","family":"Rzepecki","sequence":"first","affiliation":[{"name":"Silesian University of Technology, Department of Measurements and Control Systems, Akademicka 16, 44-100 Gliwice, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1908-5185","authenticated-orcid":false,"given":"Anna","family":"Chraponska","sequence":"additional","affiliation":[{"name":"Silesian University of Technology, Department of Measurements and Control Systems, Akademicka 16, 44-100 Gliwice, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7723-8063","authenticated-orcid":false,"given":"Sebastian","family":"Budzan","sequence":"additional","affiliation":[{"name":"Silesian University of Technology, Department of Measurements and Control Systems, Akademicka 16, 44-100 Gliwice, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1501-8468","authenticated-orcid":false,"given":"Chukwuemeke William","family":"Isaac","sequence":"additional","affiliation":[{"name":"Silesian University of Technology, Department of Measurements and Control Systems, Akademicka 16, 44-100 Gliwice, Poland"}]},{"given":"Krzysztof","family":"Mazur","sequence":"additional","affiliation":[{"name":"Silesian University of Technology, Department of Measurements and Control Systems, Akademicka 16, 44-100 Gliwice, Poland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9494-3744","authenticated-orcid":false,"given":"Marek","family":"Pawelczyk","sequence":"additional","affiliation":[{"name":"Silesian University of Technology, Department of Measurements and Control Systems, Akademicka 16, 44-100 Gliwice, Poland"}]}],"member":"1968","published-online":{"date-parts":[[2020,7,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"942","DOI":"10.1016\/j.promfg.2020.01.395","article-title":"Effect of Occupational Exposure to Noise on the Health of Factory Workers","volume":"39","author":"Lai","year":"2019","journal-title":"Procedia Manuf."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"200","DOI":"10.1016\/j.proeng.2017.09.274","article-title":"The relationship between psychomotor efficiency and selected personality traits of people exposed to noise and vibration stimuli","volume":"199","author":"Korchut","year":"2017","journal-title":"Procedia Eng."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"852","DOI":"10.1177\/1461348418782166","article-title":"Experimental attenuation and evaluation of whole body vibration for an off-road vehicle with magnetorheological dampers","volume":"38","author":"Krauze","year":"2019","journal-title":"J.
