Vpliv površinske obdelave na akustične lastnosti lesenih resonančnih plošč [Elektronski vir] : diplomsko delo = Influence of surface treatment on acoustic properties of wooden resonant panels : B. Sc. ThesisSkrt, JakobV raziskavi smo preverjali akustične lastnosti smrekovih (Picea abies (L.) Karst.) in javorjevih (Acer pseudoplatanus L.) lamel, dimenzij 400 mm × 75 mm × 3 mm. Akustične lastnosti lamel smo ... proučevali dinamično mehansko, s frekvenčnim odzivom pri prečnem nihanju. Lamele smo testirali neobdelane ter po površinski obdelavi s štirimi vrstami premazov: JOHA (J), domač (D), nitrocelulozni (NC) in poliuretanski premaz (PUR). Po površinski obdelavi se je povečala povprečna gostota lamel, bolj pri smrekovih, lastna frekvenca pa se je značilno zmanjšala. Površinski premazi, zlasti mehkejši (J, D, NC), še posebej pri smrekovini, so značilno povečali dušenje mehanskega nihanja (tanδ) lamel po površinski obdelavi. Akustične lastnosti lamel so se najmanj spremenile po površinski obdelavi s poliuretanskim lakom, ki pa značilno poveča gostoto in s tem težo resonančnih plošč. Nasprotno, pa je premaz JOHA najmanj vplival na povečanje teže resonančnih plošč, negativni učinki na relevantne akustične lastnosti (Δtanδ = +28,24 %. ΔACE = -30,44 %), pa so bili relativno majhni.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
