摘要： 声波共振管教学实验是理解声波的传播、叠加和共振物理问题的基础，也是了解驻波法测量材料吸声系数和声阻 抗的基础.通过对非理想条件下的实验现象的观察，可以促进学生进一步思考，理解声波的增强和减弱及其在工业领域的应 用.本文就声波共振管教学实验中最小共振频率测量、管中驻波声压分布及其管口修正等问题进行了探讨.
关键词: 声波共振管, 最小共振频率, 声场分布, 管口修正
Abstract: Teaching experiments of acoustic resonance in tubes are bases not only to understand the physical phenomena of acoustic wave propagate，superposition and resonance，but also to understand the basic physic mechanism of measuring the sound absorption coefficient and acoustic impedance of materials. Some non-ideal conditions in this experiment can promote students to think further，and to understand the enhancement and attenuation of sound wave and its application in the field of industry. Measurement of the minimum resonant frequency，sound pressure distribution of waves and end corrections are investigated.
Key words: acoustic resonance tube, minimum resonance frequency, sound field distribution, end corrections
