| 中文摘要: |
| 声脉冲法是近代现场隔声测试和吸声测试技术的主要方法之一,但声脉冲信号的产生是阻碍其应用的一个难点。本文以AT89C52单片机和DAC0832模∕数芯片为核心,设计一种声脉冲信号发生器,具有结构简单,成本低廉,使用方便的特点。经过测试,给出了该声脉冲信号发生器所产生声脉冲信号的时频域波形图。 |

| The sound impulse testing method is one of the primary measures in the sound insulation and absorption field-testing technique.One of the difficulties which hinder its application is how to generate a desired sound impulse.This paper introduces a design of the sound impulse generator which is based on the AT89C52 single-chip microcontroller and the DAC0832 analog-to-digital converter.This sound impulse generator is very simple,low cost and convenient to use.The impulses it generates are tested and their time-domain and frequency-domain waveforms shown. |
