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
