Sound is important in radio dramas to set the atmosphere and keep listeners interested through effects and music. Silence identifies scene changes or ends through fading. Fades also mark the end or beginning of scenes or episodes. Music is key to creating atmosphere, and larger productions may include jingles. Dialogue tells the story through a range of accents and cultures to sound realistic, as required by equality laws. Words and voices are the backbone of radio dramas, using narration and description to set the scene, develop characters, and help listeners visualize the story clearly.

1. Sound & Silence
Sound is important because it will set the atmosphere and keep the
target audience interested with the use of sfx, atmospheric music. Breaks
in that sound (silent areas) will identify a scene change or the end of the
production usually with an exponential fade at the end of the sequence
or the clip. The sound is always recorded on professional microphones
rather than on location.
Use Of Fades
Fades can identify the end/start of a scene or the end of an episode, it is
the equivalent of a dip to black in video production. As a Radio Drama is
purely just sound, the change in a scene needs to be obvious and easily
recognized.
Music
The music will be key in creating atmosphere for the Radio Drama, if it is a
large production it will also have a jingle, same sort of thing that would
be found at the beginning of a EastEnders show for TV.
Speech/ Dialogue
The Speech is self explanatory, it is how the words are said and could
include someone with a speech impediment, or vocal defect or
multicultural backgrounds and accents this makes the Radio Drama sound
like it has a wider range of people just like the real world, It is also
required due to equality laws. If the drama was just a white, British man
and woman talking the dialogue will be far less real and interesting. The
dialogue will give the information and tell the story and by having a range
of accents and cultures it will sound far more real and professional .
Words and Voices
The Words and voices used in a Radio Drama are the backbone
of the whole production, they can set the scene by use of
narration and description develop characters, it can be written in
a specific way and include specific accents, this also helps set the
scene and give the audience a better picture in their head. It is
important because it will give the Radio Drama a more realistic
feel. The main objective of a radio drama is to make the listeners
see the story in their mind as the writer/directors see it in theirs,
It needs to be clear as day.
