急用：请英语高手帮忙翻译一段文字，小弟感激不尽

声级计以其简单，方便，成本低，精度高等一系列优点，成为航空器噪音测量方面主要的测量仪器之一。目前利用声级计进行测量的传统方式，大多都是多点循环测量。由于在航空噪音的测量过程中，仪器的位置，高度等许多因素都会影响到测量结果，而且声级计在测量过程中无法获知当前飞机的功率状态等参数，这样不仅增加了测量的误差率，而且使得数据没有可比性。然而，如果利用大规模的仪器测量，不仅要耗费巨大的人力物力，而且费时费地。基于此，在了解认识噪音的基础上，同时在保证符合中国民航总局关于噪音测量的规定的前提下，能否通过计算机，利用GPS实现声级计同步测量飞机噪音，并探讨它的可行性。

Answer 1

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.

Answer 2

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.
