{"doi":"10.1121/1.2934043","title":"Array based measurement of radiated and absorbed sound intensity components","abstract":"<jats:p>Calibration of energy flow models for cabin environments requires tools able to measure the energy flow between the sub-systems of the models. Here we shall specifically consider the energy flow between acoustic energy in the cabin and vibration energy in the panels. Sound intensity measurement, for example with a two-microphone intensity probe, can provide the total sound intensity at some distance from panels. It cannot resolve, how much of the intensity is due to radiation from the surface and how much is due to absorption of energy from the sound field. And it cannot provide the information right on the panel surface, leading to a degraded resolution. The ability to distinguish between radiated and absorbed intensity is important for energy flow modeling, and for identification of the areas where noise energy enters the cabin. The present paper describes some work done to measure the radiated and absorbed intensity components by the use of a double layer microphone array. Two measurements are performed: A measurement of surface absorption coefficient and an operational measurement. Non-locally reacting surfaces represent a particular challenge, the handling of which will be discussed. Results from both loudspeaker measurements and in-flight measurements will be presented.</jats:p>","journal":"The Journal of the Acoustical Society of America","year":2008,"id":38447,"datarank":2.333371904309275,"base_score":3.1354942159291497,"endowment":3.1354942159291497,"self_citation_contribution":0.47032413238937254,"citation_network_contribution":1.8630477719199028,"self_endowment_contribution":0.47032413238937254,"citer_contribution":1.8630477719199028,"corpus_percentile":null,"corpus_rank":null,"citation_count":22,"citer_count":21,"citers_with_citation_signal":19,"citers_with_endowment":19,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":190704,"name":"Jakob Mo/rkholt","orcid":null,"position":1,"is_corresponding":false},{"id":190705,"name":"Pierre Hardy","orcid":null,"position":2,"is_corresponding":false},{"id":190706,"name":"Dominique Trentin","orcid":null,"position":3,"is_corresponding":false},{"id":190707,"name":"Martin Bach-Andersen","orcid":null,"position":4,"is_corresponding":false},{"id":190708,"name":"Graeme Keith","orcid":null,"position":5,"is_corresponding":false},{"id":190703,"name":"Jo/rgen Hald","orcid":null,"position":0,"is_corresponding":false}],"reference_count":0,"raw_metadata":{"has_enrichment":true,"base_score":3.1354942159291497,"endowment":3.1354942159291497,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"18998881","pmcid":null,"openalex_id":"https://openalex.org/W2007788470","authors":[],"funders":[],"total_grants":0,"fwci":0.7502,"citation_percentile":0.73287832,"influential_citations":0,"citation_trend":[{"year":2012,"count":3},{"year":2013,"count":3},{"year":2014,"count":1},{"year":2015,"count":1},{"year":2018,"count":2},{"year":2019,"count":2},{"year":2020,"count":1},{"year":2021,"count":4},{"year":2025,"count":2}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://pubs.aip.org/jasa/article/123/5_Supplement/3387/715630/Array-based-measurement-of-radiated-and-absorbed","host_type":"publisher"},{"url":"https://doi.org/10.1121/1.2934043","host_type":"journal"}],"fields_of_study":["Acoustic Wave Phenomena Research","Noise Effects and Management","Aerodynamics and Acoustics in Jet Flows","Physics","Engineering"],"mesh_terms":[],"keywords":["Sound intensity","Acoustics","Microphone","Energy flow","Intensity (physics)","Energy (signal processing)","Sound energy","Microphone array","Absorption (acoustics)","Sound intensity probe","Loudspeaker","Sound power","Measure (data warehouse)","Noise (video)","Calibration","Optics","Computer science","Physics","Sound (geography)","Critical distance"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Affordable and clean energy"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-06-11T03:29:54.243551Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
