Sound!

It is crucially important to human experience and to sound design in film.

Sound is important in a film production. Different aspects of sound enhance the characters and the story, making the movie a complete experience. In addition, sound is edited into the movie so it is coherent and comprehensible within the movie.

Some sort of sound is always used to enhance the movie experience. Sound in a movie includes 

1. music, 
2. dialogue, 
3. sound effects, 
4. ambient noise, and/or background noise and 
5. soundtracks. 

Music

 Music is a very important element for a movie. In the silent movie period, music was played throughout the whole movie. The film score is the music at the beginning of the movie when the credits are rolling, and it sets the atmosphere for the movie.

Music is also played at critical points during a movie. It indicate  something is going to happen,  some situations have occurred in  a movie, 

Dialogue

Dialogue is defined as a conversation between two or more people in a movie. In addition, a movie could have a monologue where a character is speaking out loud when he or she is alone. A character, for example, may contemplate the pros and cons of talking some form of action in a monologue.

A movie can also have voice-over narration. Voice-over narration is when a character is explaining what has transpired in a movie and why. 100 years ago, there were silent movies with no audio dialogue, but dialogue cards were used, and background music set the tone of the scene. Take a look at the following example of a scene with and without dialogue.

Sound Effects

It defines sound effect as “any sound, other than music or speech, artificially reproduced to create an effect in a dramatic presentation, as the sound of a storm or a creaking door.” An action movie, for instance, is more interesting and bolder with sound effects. With sound effects, the viewer gets more involved with the movie.

Sound effects are most often added into the movie post production.  player. Music and sound effects give an aspect of the character.

Ambient Noises (Background Noise)

Ambient noises are background noises that are in a room, a house, outside, or any given location.  Every location has distinct and subtle sounds created by its environment. Ambient noises are types of sound effects. Background noise gives the movie more realism.

Soundtracks

A soundtrack is an audio recording created or used in film production or post-production.  Initially, the dialogue, sound effects, and music in a film have their own separate tracks (dialogue track, sound effects track, and music track), and these are mixed together to make what is called the composite track, which is heard in the film.

Late in the 1940s “sound track” became one word, “soundtrack.”  A soundtrack or an original soundtrack from a movie became a way of advertising the movie.
