We call audiovisual media the mass media that call for the use of the senses of sight and hearing to convey their messages. In other words, audiovisual media combine images and sound, for example, the receiver can see and hear the message in question. Among the most outstanding audiovisual media are: television, cinema and the internet (which has gained strength in recent decades).
It should be noted that the means of communication are instruments through which a communication process can be implemented
No doubt , the incorporation of sound to cinema, in 1920, determined the start of this combination. As is well known, until that moment it was only possible to see images through the seventh art, popularly known as silent cinema, from which actors like Charles Chaplin became so popular. The most that had been done in this regard was the presentation of live orchestras that gave sound to the silent film through music.
However, these two universes that united image and sound would bring a multiplicity of novelties and also new concepts. For example, the action of integrating sound into image is called montage.
Both sound and image can be expressed on various media, such as tape, DVD, CD, among others, which allows them to be stored simultaneously
When image and sound come together, a sensory and original reality is created that triggers various experiments, such as: complementarity (as each contributes with its uniqueness), harmony (each sound corresponds to an accompanying image) and reinforcement (because the meanings each express by itself are enhanced by the combination).
