Abstract

Uncertainty measurement is one of the important indexes to quantitatively describe the quality of measurement results, which directly reflect the reliability, feasibility and comparability of the measurement results, meanwhile, keep the noise measured under the requirement of quality control. In this paper, By designing the air noise test of ship air compressor and scientifically calculating the uncertainty of the test, Starting from many factors affecting the vibration and noise test, and considering all factors affecting the test results, the scientific analysis system of uncertainty is used. A good reference basis is provided for the uncertainty calculation of subsequent tests. firstly measure the air noise of marine equipment based on GJB 4058-2000, then according to JJF 1059-2012, analyze and evaluate the uncertainty of measurement in detail: analyzing the sources of measurement uncertainty as well as giving the results of measurement uncertainty. scientific protection of sound level meter and other precision equipment should be considered especially. The environment in which the sound level meter is placed has a great influence on the sensitivity of the sound level meter, so the effectiveness of measurement can be improved by placing the sound level meter in the incubator after the measurement verification. This research is suitable for practical application.
