The study aims to assess how a locally constructed enclosure affects a portable generator's noise generation and heat buildup, to address the risks posed by generator noise. This study compares working conditions with respect to sound level and engine temperature across three enclosure models and non-closure cases. The first model uses an air cavity between the plywood panels; the second model uses reeds as the insertion material; and the third model uses shredded plastics as the insertion material. The sound intensity (dB) at 3 and 5 m is obtained. In addition, the generator engine temperatures are also recorded. These recordings were obtained for generator loads of 0%, 25%, 50%, 75%, and 100%, both during the day and at night. The results show that the third model (i.e., the shredded-plastics model) achieves the most significant noise reduction. In contrast, the first model (i.e., the best in thermal performance) achieves the best thermal performance.
