The principle and purpose of the sound tube with a diameter of 4.0 X 3.0 are demonstrated: sound will undergo changes due to reflection, and sound waves will propagate faster in metal than in air. This results in the continuous superposition of sound inside a long metal tube, and finally a mixed sound will be heard at the other end.
