Zveza med absorpcijo udarnega zvoka in trdoto lesenih talnih oblog : diplomski projekt = Relationship between the impact noise absorption and hardness of wood flooring : B. Sc. thesisSmrekar, Jernej, 1993-Raziskovali smo ali obstaja zveza med emitiranim udarnim zvokom in trdoto lesov in masivnih lesenih talnih oblog. V raziskavi smo proučili preizkušance smrekovega, macesnovega, hrastovega, bukovega ... ter jesenovega lesa, nominalne debeline 20 mm. Trdoto lesa smo določili s standardno Brinellovo metodo, ter z dinamično metodo s spuščanjem jeklene kroglice, pri kateri smo izmerili še akustični odziv. Ugotovili smo naraščanje trdote lesa z večanjem gostote lesnih vrst. Potrdili smo tudi odvisnost velikosti površinske poškodbe lesa pri padcu jeklene kroglice s premerom vtiska kroglice pri standardni Brinellovi metodi. Z večanjem vtiska kroglice pri dinamični metodi smo potrdili nižji izmerjen maksimalni-, eksponentni povprečni- ter povprečni zvočni tlak. Širina frekvenčnega spektra izmerjenega zvočnega signala je bila večja pri mehkejših lesnih vrstah. Rezultati tudi potrjujejo, da so za mirne prostore zaradi manjšega emitiranega udarnega zvoka primernejše lesene talne obloge iz mehkejših lesnih vrst.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
