Oil-heat treatment (OHT) can influence the acoustic properties of resonant wood, such as spruce. In this study, the effect of OHT on spruce wood was evaluated, using palm oil as a heating medium, at four different temperatures: 140, 160, 180 and 200 \u00b0C. Physical, mechanical and acoustic properties of spruce wood were evaluated before and after OHT and included the following: density, modulus of elasticity in the static bending test, and wood sound velocity. The acoustic parameters after OHT improved; however, the samples bent after modification had a higher modulus of elasticity, with a simultaneous deterioration of the acoustic parameters. The dynamic modulus of elasticity increased by 11%, and the musical constant by 5%. The static modulus increased by more than 3.5%, but the acoustic parameters calculated on the basis of these results indicated a deterioration of the acoustic properties of completely oven-dried wood. The increase in moisture content to air-dried condition contributed to a slight increase in the mean musical constant at the highest modification temperature.<\/jats:p>","DOI":"10.3390\/ma13081962","type":"journal-article","created":{"date-parts":[[2020,4,23]],"date-time":"2020-04-23T02:10:52Z","timestamp":1587607852000},"page":"1962","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Acoustic Properties of Resonant Spruce Wood Modified Using Oil-Heat Treatment (OHT)"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0784-6258","authenticated-orcid":false,"given":"Przemys\u0142aw","family":"Mania","sequence":"first","affiliation":[{"name":"Department of Wood Science and Thermal Technics, Faculty of Wood Technology, Pozna\u0144 University of Life Sciences, Wojska Polskiego 38\/42, 60-627 Pozna\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mateusz","family":"G\u0105siorek","sequence":"additional","affiliation":[{"name":"Department of Wood Science and Thermal Technics, Faculty of Wood Technology, Pozna\u0144 University of Life Sciences, Wojska Polskiego 38\/42, 60-627 Pozna\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Bucur, V.
