Abstract

A portable generator is a one of sources that affect the environmental noise. Although the noise level might not harm the human hearing, the noise emitted by a portable generator causes disturbance to the environment. In practice, most people do not cover the portable generator to reduce its noise emission. In this project a simple box-shaped, for portable generators For this project, the sound power level emitted by a portable generator was measured according to ISO 3746. From this, a single partition of noise enclosure was design using mild steel panel having thickness 4 mm. It is found that the sound power level can be reduced by 13dBA. However this is not agree well with the theory due to compromised situation in the design, such as the introduction of holes for air intake and exhaust.
