• radio is a blind medium
• uses speech as the primary mode of communication 
• essentially and primarily auditory, consisting of speech, music, sounds and silence. 
• identifying and de-coding a number of signs and symbols
• connect the signifier (the thing you hear) and the signified (what it means): Ferdinand de Saussure

C. S. Pierce: icon, index and symbol

•  an ICONIC SOUND will actually sound like its’ object – person
• An INDEXICAL SOUND, will create an association to it’s object – sound of movement (this changes through microphone placements, sound processing and reverb
• SYMBOLIC SOUND is one that is more arbitrary, random and vague – sound effects (echo)

• Radio, like moving image, is LINEAR and SEQUENTIAL, in that it moves in a chronological order, from (a) beginning to (an) end. In this respect, it is important to refer to NARRATIVE THEORY when trying to understand and de-code radio meaning
