enclosures. The barrier was a wall located behind the firing line, and the partial enclosure was an open front shed with the firing line located within the shed. Results of the experiments showed that the shed did not outperform the rear wall, a significant outcome because walls are less expensive to build than sheds. Evidence

AbstractIt has been realized that attenuation of the noise radiated from diesel engine generating sets is a challenge for the designer. The enclosure, which may be designed for noise reduction, has to allow for the flow of the necessary amount of air. The present work is an attempt to tackle such a contradictory problem. A mathematical model is

A proper design of noise barriers would need due considerations from both acoustic and non-acoustic aspects. Acoustical design considerations include barrier material, barrier locations, dimensions and shapes. However, they are not the only requirements leading to proper design of noise barriers.

Temporary barriers can be employed and/or enclosures can be built around noisy equipment. These techniques can significantly reduce noise levels and, in many cases, are relatively inexpensive. These barriers can typically be constructed on the work site from common construction building material (plywood, block, stacks, or spoils). Enclosures are often constructed from commercial panels lined
