The phenomena that develop in our environment are innumerable, however, we can say that the movement, light and sound, are the most indispensable for our lives, and also for all living species that are cohabiting with us on this beautiful planet which we have called Earth, therefore, in relation to the above expressed in this opportunity I wanted to share with you all in a general way the generation of the phenomenon of sound, and thus, to highlight its great and essential importance for all of us.
If we focus on the tool for obtaining and interpreting the phenomenon of sound, we must undoubtedly talk about the science of acoustics, since this sub-branch of physical science is known as the science of sound, then, it is responsible for knowing how sound is generated and propagated through a given material or elastic medium, and when the sound moves from one side to the other, we will find other intrinsic phenomena such as reflection, absorption, refraction, diffraction, among others.
Therefore, just as our eyes can capture the images of our environment, our auditory system (ears) can perceive the different sounds around us, but it is important to mention that for the phenomenon of sound to develop, there must undoubtedly be some kind of vibration of the component particles of any body or object that emits sound. When this happens, sound waves are generated, which propagate through space-time where the source of sound generation is located until these waves reach our ears.
According to the above we can highlight how the generation of sound depends on the fundamental phenomenon of movement and in particular the vibratory motion, and this movement belongs to the family of oscillatory movements, and that no doubt, are found in any space-time of our universe because everything has some form of vibration and thus sound, although often we can not perceive these sound waves, however, are always present at our side and at any time where we find ourselves.
The phenomenon of sound
As already stated, for sound to be generated it is necessary that the component particles of any body or object begin to vibrate and thus begin to form sound waves which undoubtedly manage to disturb the tranquility of the material medium through which these waves propagate to reach a receiver of sound that can be our ears, usually, the medium of sound propagation is the air, but it can also do it through a liquid or solid medium, but, in other deliveries we will be relating to this propagation in the material media described above (liquids and solids).
The sound can be generated both artificially and naturally, this will depend on the source of generation of these sound waves, and as we know, these sources mentioned above can be represented by many examples that we can observe in our environment, which is why we will show an example of generation of the phenomenon of sound artificially as you can see in the following image gif.
As you could visualize when releasing the tip of the antenna (once pressure was exerted on it) it began to oscillate or vibrate from one side to the other of its stable equilibrium point, and thus disturbing the air molecules around it, and thus generating sound waves that go out to propagate through the material medium until they reach our ears as receivers of the sound, and this is an example of so many others that we can find around us, now we can witness the generation of sound naturally, and of course, the best example of which we could witness is the vibratory movement of our vocal cords, and thus, generating the sound of our voice as you can see below in the following animated gif.
As you could see my dear readers we met two examples of generation of the phenomenon of sound both artificially and naturally, the truth is that for this there must always be a vibration of the component particles of a particular body or object which emits sound, and also, the vibratory motion is everywhere and thus the sound is too.
Thanks to the interpretation of essential phenomena developed in nature is that man has managed to increase its longevity in this universe, and all this thanks to the remarkable action of science-education, as one extracts the knowledge and the other has spread all this knowledge to the rest of humanity, which is why we must always highlight the great work done by both the field of science and education.
In this article we begin to relate to the wonderful phenomenon of sound and especially how it is generated and the same as has been expressed depends on another essential phenomenon such as the movement especially the vibratory and without vibration there will never be sound, therefore, when we perceive with our auditory systems (ears) any sound think that there is also a vibration of the component particles of the body emitting such sound waves.
In other deliveries we will continue related to other characteristics of sound and other intrinsic phenomena when these sound waves propagate through certain material or elastic media such as air, liquids or solids, highlighting that in a vacuum the sound waves do not propagate, so until another opportunity my dear readers.

Hi @rbalzan79, congratulations for this very didactic and well illustrated post.
Enjoy your content, and I will be watching for your next posts related to the sound emission and its propagation in different media.
Thanks for sharing and teaching!
Thank you for your positive comment on my article. Regards friend.
