Sound is a wave produced by the vibration of an object, which is transmitted to our ears through a certain medium and is finally perceived by us.

Different objects vibrate at different frequencies and produce different pitches. Different objects vibrate at different amplitudes and produce different sound intensities. Different sounds have different durations and produce different sound lengths. Different objects have different vibration waveforms and produce different timbres. These elements interact during the propagation of sound and together shape our auditory experience.

With the development of technology and society, the form and function of sound are constantly evolving. In ancient times, people mainly transmitted information through word of mouth and percussion instruments. These methods are all primitive sound transmission methods and are also the basis of modern sound transmission. With the rise of the industrial revolution, mechanical sound-producing equipment began to appear, such as the roar of steam engines, the sounds of clocks and other mechanical devices, etc. In modern society, the forms and functions of sound are more diverse.

As an important medium, sound plays an indispensable role in the development of human civilization. 】
