This study deals with noise problem at the Indonesian teak wood furniture manufacturing company called PT Jawa Furni Lestari. The noise is generated by air compressor which is used for dyeing and spraying processes in the assembly area. The highest noise intensity indicates the value of 106.28 dB, which passes the threshold value i.e. 85 dB. The aim of this study is to reduce the noise level by constructing noise barrier. We used Pahl and Beitz approach for the barrier development process and modified idle space under the stairs in the assembly area. Consequently the compressor must be relocated from its present location. The result of the study shows that the construction of the barrier could reduce noise by 32.29 dB. In addition to reducing noise due to barrier construction, compressor relocation provides larger area for production activities. The evaluation result shows that the operators in the assembly area are very satisfied with the condition after the barrier is constructed.
