一、引言在许多应用方面,传声器系统需要在高声强的条件下进行校准。有些传声器或其他压强换能器常常需要在甚低频范围内进行校准。为此,工业上需要一种简单、廉价的校准器。本文描述的新型校准器,对此种要求就简单化了。校准器是用一个小振动台驱动一个大面积的活
I. INTRODUCTION In many applications, microphone systems need to be calibrated under loud and loud conditions. Some microphones or other pressure transducers often require calibration at very low frequencies. To do this, there is a need in industry for a simple, inexpensive calibrator. The new calibrator described in this article simplifies this requirement. Calibrator is a small shaker to drive a large area of living
