| Abstract: | This thesis is based on the speed of sound testing experimental instrument to measure the propagation ve- locity of sound in the air, as well as by means of acoustic interference, diffraction and reflection principle. The ex- perimental research on the one hand deepens the understanding of the acoustic wave characteristics, on the other hand provides a variety of measuring the speed of sound experimental methods, enriches the experiment content, but also to expand the use of the speed of sound testing experimental instrument. |
