This thesis deals with the design and testing of the acoustic enclosure for the Inova hydraulic actuator. The purpose of this enclosure is the acoustic insulation of the actuator and its parts, to achieve better acoustic conditions when performing acoustic diagnostics on this device. The first part deals with the theoretical basis of acoustic enclosures, the possibilities of modelling of acoustic problems and market research in materials usable for enclosure construction. The second part deals with the analysis of actuator noise and the localization of noise sources in the laboratory. Subsequently, the choice of material and concepts of the acoustic enclosure was made. Then, the final design solution was selected. The final design solution was subjected to acoustic simulations to predict insertion loss and determine the dimensions of the enclosure. The manufactured enclosure was tested in a semi-anechoic chamber and finally on the Inova actuator. Finally, the measurement results and simulation results are compared with each other.
