Abstract: | The paper presents the development of a measurement method of some acoustic properties of materials. Based on Kundt`s method of 1902 and by using performant equipment manufactured by Bruel & Kjaer - Denmark, a modern investigation method could be established, allowing for the characterization of material properties as absorption and transmissibility. This investigation was applied to some representative Romanian materials, manufactured by Chimaltex of Targoviste. The results of the experimental research find application in the acoustic insulation of machine-tools. |
