Sound-level meter by its simple, convenient, the cost is low, the precision higher a series of merits, become one of aircraft noise measurement aspect main metering equipment.At present carries on the survey using the sound-level meter the traditional way, mostly all is the multi-dot cycle survey.Because in the aviation noise survey process, the instrument position, waits for many factors to be able highly to affect the measurement result, moreover the sound-level meter is unable in the survey process to learn current airplane parameters and so on power condition, not only like this increased the survey error coefficient, moreover enables the data not to have the commeasurability.However, if uses the large-scale instrument survey, not only must consume the huge manpower physical resource, moreover time-consuming expense.Based on this, in the understanding understanding noise foundation, simultaneously conforms to Chinese Commercial aviation Bureau in the guarantee about under the noise measurement stipulation premise, whether through the computer, uses the GPS realization sound-level meter synchronization air mapping plane noise, and discusses its feasibility.

Supermarket sales problems and countermeasures Sound Level Meter with simple, convenient, low cost, high accuracy a number of advantages, Aircraft noise measurement to become the main one of the gauges. Currently using sound level meter to measure the traditional way, most are multi-point measurement cycle. As aviation noise in the measurement process, equipment location, height and many other factors will affect the measurement results, and the measurement of sound level meter course not informed of the current state of aircraft parameters such as power, This will not only increase the measurement error rate, but it is no comparable data. However, use of large-scale measuring instruments, not only to spend enormous human and material resources, but also time-consuming and expensive to. Based on this, to understand on the basis of noise, At the same time ensure compliance with the Civil Aviation Administration of China on noise measurement of the premise, whether by computer, use GPS synchronized sound level meter measurement of aircraft noise and explore its feasibility.
