We aimed at the establishment of the noise measurement methods of the engines, the evaluation of the noise reduction devices, and the acquisition of the engine test techniques in the open-air field. So we carried out open-air field engine tests at Noshiro Testing Center since 2004. Because of a remote location and a short period, it was necessary to check carefully the function of equipment parts for tests and the function and performance of the engine in advance. Therefore we thought it was important to put summaries of the test including the test preparations in order because we carried out the next open-air field engine tests efficiently. So we wrote this report about the fourth open-air field engine tests that we carried out in August, 2007.
