Analysis of and Compensation for the Dynamic Characteristic of Microphone Transmitting the Sound Signal

摘要

A new idea is provided to improve the capability of microphone converting sound waves in the paper. From the point view of measurement technology, the performance of microphone converting sound waves is relevant to its dynamic error. Under the preconditions that other conditions make no difference, the dynamic error between different grade microphones is given in the paper according to the transfer functions of the sound transfers system on PC under the conditions of different grade microphones. The transfer function of the multimedia sound transfers system under the conditions of high grade microphone is regarded as standard to correct the transfer function under the conditions of low-end microphone, and the way to compensate the dynamic characteristic of low-end microphone is presented in detail to improve the capability of microphone converting sound waves. In addition, the problems met during the process of compensation are analyzed, and how to solve them is given in the paper.
