在物理教材中,介绍了用音叉做声波干涉实验,但这个实验的教学效果不明显,学生完成实验后可以听到声音忽大忽小,但它却不是由于声音的干涉引起的.不少同仁也对这一问题提出了质疑.随着电脑的不断普及,我们现在可以在课堂中使用电脑演示、探究声波的干涉现象,还可以指导学生在家中自已利用这个实验,对声波的干涉现象进行研究,可以收到令人满意的效果.一、用电脑作为信号发生器,产生标准的正弦声波COOLEDIT 软件是一种功能强大的声频处理和编辑软件,它可以生成、播放和录制我们所需要的声音,并可以显示出声音的波形供我们进行研究,是声学研究和声频处理的得
In the physics textbooks, acoustic fork interference experiment was introduced using a tuning fork. However, the teaching effect of this experiment is not obvious. After the student completes the experiment, he can hear the loudness of the sound, but it is not caused by the interference of sound. Many colleagues This question has also been questioned. With the continued popularity of computers, we can now use computers to demonstrate and explore the interference phenomena of sound waves in the classroom. We can also instruct students to use this experiment in their own home to study the phenomenon of sound wave interference. , Can receive satisfactory results. First, use the computer as a signal generator to produce a standard sine wave COOLEDIT software is a powerful audio processing and editing software, it can generate, play and record the sound we need , and can show the waveform of the sound for us to study, it is acoustic research and audio processing
