Abstract: An investigation was conducted into the reduction of the noise caused by machines used in the manufacturing industry. Four noise cabin models, outfitted with two types of insulation-materials for the cabin walls – Styrofoam (Expander Polystyrene - EPS) and CelluBOR – were constructed. For each cabin model, a high-level noise source was employed, in accordance with operation conditions, to perform noise measurement and frequency analysis. The results indicated that CelluBOR was an effective material for ensuring noise insulation.

Abstract: Relocation of the resonance frequencies of the un-damped systems to desired values adding grounded springs is addressed. For the calculatıon of the necessary springs’ stiffnesses, a method based on Sherman-Morrison (SM) formula is presented. The method uses receptances of the original system and it needs neither analytical nor modal models. Numerical simulation shows that the method is very effective.
