论文摘要
我们提出了一个家庭实验室，其中使用望远镜真空吸尘器和智能手机来研究音速和声音共振。当撞击管道或手掌靠近一端时，产生的声音将由智能手机注册。通过适当的应用，获得了共振频率。改变管道的长度并注册相应的谐振频率可以获得声速。这款家用与Covid19大流行期间最初提出的本地牌已被纳入了在新正常时期实验声学共振的家庭挑战。
We propose a home laboratory in which a telescopic vacuum cleaner pipe and a smartphone are used to investigate sound speed and acoustic resonance. When the pipe is hit or the hands clapped near one end the sound produced is registered by a smartphone. By means of an appropriate application the resonant frequency is obtained. Varying the pipe's length and registering the corresponding resonant frequency allows to obtain the sound speed. This home-lab, first proposed during covid19 pandemic, has been incorporated as a home challenge to experiment with acoustic resonance in new normal times.
