Resumo: | This thesis presents the development of an automated scanner for measuring sequential impulsive responses, to be applied on the spatio-temporal characterization of materials, used in acoustic treatment. The system uses the same type of technology as 3D printers, with a base that moves an acoustic sensor along the x, y, and z-axis. The sensor displacement is accomplished with stepper motors, controlled by an Arduino processor. Thus, a set of M impulse responses are measured sequentially with a configured array. With the M spatially-distributed impulsive responses collected, it is possible to map the spatial information in the sound field to a set of L plane waves, by solving the inverse problem with Tikhonov regularization. The built system is flexible, and different experiments can be executed accurately. This study focuses on the in situ impedance measurement. Once one computes the complex amplitudes of the L plane waves, the sound field can be reconstructed in the vicinity of the array, which allows the estimation of the surface impedance of a sound absorber. |

O sistema usa o mesmo tipo de tecnologia de impressoras 3D, com uma base que move um sensor acústico nos eixos x, y e z. A movimentação do sensor é feita por motores de passo, controlados por um processador Arduino. Assim, um conjunto de M respostas ao impulso, distribuídas no espaço, são medidas sequencialmente com o arranjo configurado. Com as M respostas ao impulso coletadas, é possível mapear a informação espaço-temporal do campo sonoro em uma série de L ondas planas, utilizando a solução de um problema inverso com regularização de Tikhonov. O sistema desenvolvido é flexível, de forma que diversos experimentos podem ser executados com exatidão. Como demonstração, a bancada é utilizada na medição in situ da impedância acústica. De posse das amplitudes complexas das L ondas planas, pode-se reconstruir o campo acústico nas imediações do arranjo utilizado, o que permite a reconstrução da impedância de superfície do material sob teste.porUniversidade Federal de Santa MariaCentro de TecnologiaPrograma de Pós-Graduação em Engenharia CivilUFSMBrasilEngenharia CivilAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessMedição de impedânciaEscaneamento do campo acústicoArranjo de microfonesDecomposição em ondas planasImpedance measurementSound field sanningArray of microphonesPlanewave decompositionCNPQ::ENGENHARIAS::ENGENHARIA CIVILDesenvolvimento de um escâner automatizado para medição sequencial e caracterização espaço-temporal de materiais acústicosThe development of an automated scanner for the sequential measurement and spatio-temporal characterization of acoustical materialsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisCarneiro, Eric Brandãohttp://lattes.cnpq.br/2876372207029481Fonseca, William D’AndreaMareze, Paulo HenriqueGomes, Marcio Henrique de Avelarhttp://lattes.cnpq.br/9410977239448827Souza, Gabriel Guimaraes Azzuz Athayde de30010000000360060060060060060079f516f9-8d92-4175-816a-516f667b958c8e8fb7b6-9996-4654-9df4-ce45ebd21d833c3863a1-29cd-4e5e-ad7b-757351050359fb71ed26-ee1f-4199-bade-ec417477e10a102d6c23-bf33-470a-87fd-11a5c94f6cacreponame:Manancial - Repositório Digital da UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGEC_2022_SOUZA_GABRIEL.pdfDIS_PPGEC_2022_SOUZA_GABRIEL.pdfDissertação de mestradoapplication/pdf49655232http://repositorio.ufsm.br/bitstream/1/27197/1/DIS_PPGEC_2022_SOUZA_GABRIEL.pdf865e0a60c72dbb1aa96a6e87cff7c19bMD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8805http://repositorio.ufsm.br/bitstream/1/27197/2/license_rdf4460e5956bc1d1639be9ae6146a50347MD52LICENSElicense.txtlicense.txttext/plain; charset=utf-81956http://repositorio.ufsm.br/bitstream/1/27197/3/license.txt2f0571ecee68693bd5cd3f17c1e075dfMD531/271972022-12-01 15:11:11.805oai:repositorio.ufsm.br:1/27197TElDRU7Dh0EgREUgRElTVFJJQlVJw4fDg08gTsODTy1FWENMVVNJVkEKCkNvbSBhIGFwcmVzZW50YcOnw6NvIGRlc3RhIGxpY2Vuw6dhLCB2b2PDqiAobyBhdXRvciAoZXMpIG91IG8gdGl0dWxhciBkb3MgZGlyZWl0b3MgZGUgYXV0b3IpIGNvbmNlZGUgw6AgVW5pdmVyc2lkYWRlCkZlZGVyYWwgZGUgU2FudGEgTWFyaWEgKFVGU00pIG8gZGlyZWl0byBuw6NvLWV4Y2x1c2l2byBkZSByZXByb2R1emlyLCAgdHJhZHV6aXIgKGNvbmZvcm1lIGRlZmluaWRvIGFiYWl4byksIGUvb3UKZGlzdHJpYnVpciBhIHN1YSB0ZXNlIG91IGRpc3NlcnRhw6fDo28gKGluY2x1aW5kbyBvIHJlc3VtbykgcG9yIHRvZG8gbyBtdW5kbyBubyBmb3JtYXRvIGltcHJlc3NvIGUgZWxldHLDtG5pY28gZQplbSBxdWFscXVlciBtZWlvLCBpbmNsdWluZG8gb3MgZm9ybWF0b3Mgw6F1ZGlvIG91IHbDrWRlby4KClZvY8OqIGNvbmNvcmRhIHF1ZSBhIFVGU00gcG9kZSwgc2VtIGFsdGVyYXIgbyBjb250ZcO6ZG8sIHRyYW5zcG9yIGEgc3VhIHRlc2Ugb3UgZGlzc2VydGHDp8OjbwpwYXJhIHF1YWxxdWVyIG1laW8gb3UgZm9ybWF0byBwYXJhIGZpbnMgZGUgcHJlc2VydmHDp8Ojby4KClZvY8OqIHRhbWLDqW0gY29uY29yZGEgcXVlIGEgVUZTTSBwb2RlIG1hbnRlciBtYWlzIGRlIHVtYSBjw7NwaWEgYSBzdWEgdGVzZSBvdQpkaXNzZXJ0YcOnw6NvIHBhcmEgZmlucyBkZSBzZWd1cmFuw6dhLCBiYWNrLXVwIGUgcHJlc2VydmHDp8Ojby4KClZvY8OqIGRlY2xhcmEgcXVlIGEgc3VhIHRlc2Ugb3UgZGlzc2VydGHDp8OjbyDDqSBvcmlnaW5hbCBlIHF1ZSB2b2PDqiB0ZW0gbyBwb2RlciBkZSBjb25jZWRlciBvcyBkaXJlaXRvcyBjb250aWRvcwpuZXN0YSBsaWNlbsOnYS4gVm9jw6ogdGFtYsOpbSBkZWNsYXJhIHF1ZSBvIGRlcMOzc2l0byBkYSBzdWEgdGVzZSBvdSBkaXNzZXJ0YcOnw6NvIG7Do28sIHF1ZSBzZWphIGRlIHNldQpjb25oZWNpbWVudG8sIGluZnJpbmdlIGRpcmVpdG9zIGF1dG9yYWlzIGRlIG5pbmd1w6ltLgoKQ2FzbyBhIHN1YSB0ZXNlIG91IGRpc3NlcnRhw6fDo28gY29udGVuaGEgbWF0ZXJpYWwgcXVlIHZvY8OqIG7Do28gcG9zc3VpIGEgdGl0dWxhcmlkYWRlIGRvcyBkaXJlaXRvcyBhdXRvcmFpcywgdm9jw6oKZGVjbGFyYSBxdWUgb2J0ZXZlIGEgcGVybWlzc8OjbyBpcnJlc3RyaXRhIGRvIGRldGVudG9yIGRvcyBkaXJlaXRvcyBhdXRvcmFpcyBwYXJhIGNvbmNlZGVyIMOgIFVGU00Kb3MgZGlyZWl0b3MgYXByZXNlbnRhZG9zIG5lc3RhIGxpY2Vuw6dhLCBlIHF1ZSBlc3NlIG1hdGVyaWFsIGRlIHByb3ByaWVkYWRlIGRlIHRlcmNlaXJvcyBlc3TDoSBjbGFyYW1lbnRlCmlkZW50aWZpY2FkbyBlIHJlY29uaGVjaWRvIG5vIHRleHRvIG91IG5vIGNvbnRlw7pkbyBkYSB0ZXNlIG91IGRpc3NlcnRhw6fDo28gb3JhIGRlcG9zaXRhZGEuCgpDQVNPIEEgVEVTRSBPVSBESVNTRVJUQcOHw4NPIE9SQSBERVBPU0lUQURBIFRFTkhBIFNJRE8gUkVTVUxUQURPIERFIFVNIFBBVFJPQ8ONTklPIE9VCkFQT0lPIERFIFVNQSBBR8OKTkNJQSBERSBGT01FTlRPIE9VIE9VVFJPIE9SR0FOSVNNTyBRVUUgTsODTyBTRUpBIEEgVUZTTQosIFZPQ8OKIERFQ0xBUkEgUVVFIFJFU1BFSVRPVSBUT0RPUyBFIFFVQUlTUVVFUiBESVJFSVRPUyBERSBSRVZJU8ODTyBDT01PClRBTULDiU0gQVMgREVNQUlTIE9CUklHQcOHw5VFUyBFWElHSURBUyBQT1IgQ09OVFJBVE8gT1UgQUNPUkRPLgoKQSBVRlNNIHNlIGNvbXByb21ldGUgYSBpZGVudGlmaWNhciBjbGFyYW1lbnRlIG8gc2V1IG5vbWUgKHMpIG91IG8ocykgbm9tZShzKSBkbyhzKQpkZXRlbnRvcihlcykgZG9zIGRpcmVpdG9zIGF1dG9yYWlzIGRhIHRlc2Ugb3UgZGlzc2VydGHDp8OjbywgZSBuw6NvIGZhcsOhIHF1YWxxdWVyIGFsdGVyYcOnw6NvLCBhbMOpbSBkYXF1ZWxhcwpjb25jZWRpZGFzIHBvciBlc3RhIGxpY2Vuw6dhLgoKRepositório Institucionalhttp://repositorio.ufsm.br/PUBhttp://repositorio.ufsm.br/oai/requestopendoar:39132022-12-01T18:11:11Manancial - Repositório Digital da UFSM - Universidade Federal de Santa Maria (UFSM)false |
