有几种方法可以直接测量和计算等效连续声压级Leq。根据测量的用途、所要求的测量精度和速度以及实际设计成本情况,仪器设计员不得不选择合适的电路,并采用一些必要的折衷措施。列举了一些惯用直接测量和计算的方法,分述了其优缺点。说明了两种测试方法及其对鉴定各种仪器设计质量的影响。 There are several ways to directly measure and calculate the equivalent continuous sound pressure level Leq. Depending on the purpose of the measurement, the required measurement accuracy and speed, and the actual cost of the design, the instrumentation designer has to select the appropriate circuit and apply some necessary trade-offs. Some commonly used methods of direct measurement and calculation are listed, and their advantages and disadvantages are described. Illustrates two test methods and their impact on qualifying the design quality of various instruments.
