高中物理的声学中有关响度、音调、噪声、乐音这部份教材,教学起来十分枯燥无味,学生听起来也无精打彩,对音调和响度概念也往往混淆不清,笔者曾经利用实验室中原有的仪器设备进行组配,做了一些实验,结合讲解,让学生边看边听,对活跃学习气氛,增进概念理解很有效果,并且实验装置也比较简易,今简单介绍如下: In the acoustics of high school physics, teaching materials such as loudness, pitch, noise, and tone are very boring to teach. Students also seem to be indifferent, and the concepts of pitch and loudness are often confused. I used the original in the laboratory. The instruments and equipment were combined, some experiments were done, combined with explanations, allowing students to listen while listening, to have an active learning atmosphere, to enhance conceptual understanding, and the experimental setup was also relatively simple. This brief introduction is as follows:
