Abstract
Numerous machines used to execute public works projects produce noise, and in the past noise measurements were performed assuming project noise is produced by a single sound source. But to perform practical noise prediction, the quantity of noise from each machine must be obtained. The authors used a microphone array to study the analysis of the noise produced by individual machines, and simulated noise of construction machines from multiple sources, verifying that it is possible to perform analysis in anechoic room and semi-anechoic room.
