Radios transmit information in audio form that is heard by a listener
and interpreted. Televisions transmit both visual and audio
information that is seen and heard simultaneously the viewer and
interpreted. You appear to be mixing up the concepts of broadcast
audio and visual information. The pure listener may conjure up an
image of what could be going on, but the success or failure of that
imagery is dependent entirely on the ability of the reader at the
radio station to accurately convey audio information about the scene.


Visual information has always been transmitted and received by radio.
Even before the pictures.


Actually, there is an entire division of audio sciences dedicated to
the study of visual images created by audio only.


Interpretation is a part of that, true. But not as much as you may
imagine. Do some reading. Even Harry Olson addresses this as far back as
the 40's. And studies have shown that there are visual cues in audio
information that are astonishingly common to the bulk of listeners.
Simple phase relationships in stereo will create images in listeners
minds, that when sketched by different individuals, in separate
locations in the stereo field, even in different locations of test, the
images drawn resemble each other.


All of which is getting deeper into this matter than is necessary for
the point...and that point is that aural input creates visual information.


The eyes are not necessary to see the pictures. The National
Federation of the Blind has been carrying this evangel for decades. And
in all but a handful of TV shows over the last 60 years, only the audio
was necessary to create the full measure of the experience of a show in
the listener.


Radio dramas written for radio contain the same
audible visual cues as drama written for TV.


Listen carefully to the dialog. There's a great deal of verbal
exposition, even, if not especially, in shows like CSI. And surveys
support that respondents get the same level of detail and understanding
by listening to the audio only that they do watching video with audio.


The writing is still the same as it was in the days of Inner Sanctum
and the Shadow. The production still uses the same effects.


Consider the number of blind people that 'watch' TV regularly. Jose
Feliciano went into exquisite detail on Letterman some years ago about
this.


Try this:


Next time you're watching CSI, turn the audio up, go into the next
room and begin a hobby. Build a model. Repair a radio.


You'll see everything on the screen. Except you'll see it in your
mind's eye, where the images are dramatically clearer and always exactly
what you expect them to be. It will take some practice, and it will take
a while, but you'll get it.


Just as generations of radio listeners did before you.- Hide quoted text -

Visual images are not in any way transmitted by radio. Only audio
information is transmitted by radio. That audio information is
interpreted by our brain and sometimes, if the radio broadcaster is
successful in his description and we are alert some of that audio
information is translated into visual images within our mind. But no
visual images are transmitted by radio.


- The mental translation of audio information into visual images can
- have results that are much less precise than a broadcast picture.
- Nonethless audio only broadcasts can certainly be entertaining.
