STUDIO DESIGN OF
RADIO STATION
Studio Design of radio is different from the television. It
is extremely sensitive because the medium completely involves ‘audio’ as the
massage in the process of Communication.
the following main segments are discussed below:
LOCATION
The building of radio station should be located at
reasonably quite site. It should be free from busy roads factories markets and
railway tracks in order to prevent the studio from external voices as much as
possible.
Other main features in the design of radio station carries
following
1. Walls
and Floor
Thick and
heavy walls constructed by solid bricks or concrete. Sometimes it is carpeted
by wood or ceramic to absorb the sound waves. Sound absorption in walls is
directly related to the resonant behavior of the walls. Therefore wood is
considered to be a better protection against the external sound. Gypsum board
is also used for this purpose. There is
a cubical room which is called console or control room, presenter has to enter
in that room then he will enter into the studio to avoid external hindrance.
There is a plush carpet over a thick pad on the floor so as to avoid the noise
of foot. The room is centrally air-conditioned so as to avoid the noise of the
wings of fan. A flat rubber material is used in a door that doesn’t fit well so
as to move the door smoothly. A brush material is use for the sliding surfaces.
2. Studio
acoustic
Studio must
be design to break up the sound waves to prevent the building momentum and to
make a room good for hearing music and sounds which is called acoustics. All
acoustic problems can be controlled by making every surface absorptive,
completely deadening the room. The problem is that all absorptive materials are
frequency selective. As a general rule, high frequency sound is absorbed more
readily than low.
Echo
Echo is
defined as a faint sound resembling the original sound. Which must be avoided
in the studio of radio for this the walls of the studio are not plain which
could reflect the voice in a regular path.
Reverberation
It is the
persistence of sound in a particular space after the original sound is removed.
Reverberation, or reverb, is created when a sound is produced in an “enclosed
space” A reverberation is perceived when the reflected sound wave reaches your
ear after the original sound wave. Since the original sound wave is still held
in memory, there is no time delay between the perception of the reflected sound
wave and the original sound wave. The two sound waves tend to combine as one
very prolonged sound wave. To avoid reverberation in the studio the walls of
the studio are designed to break the regular path of the sound waves which is
similar to the avoidance of echo.
3. Internal sound
Internal sound includes sound of bangles, anklet, clock,
mobile phone and noise of shoes that must be avoided. For this the presenter
must remove all the accessories which they are carrying, switched off their
mobile phones, and remove their shoes before entering into the studio. Wind
screen (upper part of the microphone) is covered by foam in order to silence
the speaker’s sound of breath.
4. Glass window
A triple glazed glass window is placed between the
control/console room and the studio. It is useful to have a non-verbal
communication so that the presenter can easily be in contact with the control
room likewise the audio controller and producer can take a look inside the
studio.
5. Microphone
Microphone converts the sound wave into electromagnetic
wave. It magnifies the frequency of sound. Stationary microphone is used in the
studio which is attached to a stand. It is placed at a specific distance and presenters
do not need to hold it.
*Cough key
A switch which is under the control of the presenter through
which he may disconnect the microphone from the console room.
6. Turntable
These are the high quality record players. A studio may have
2 to 3 turntables.
7. Cue sheet
It contain schedule of programs which is to be broadcast .It
is in the control room. The detail of all the programs is written in the
cue-sheet except the advertisements.
8. Log book
It contains the records of programs which have been
transmitted. If there is any program which has not been aired due to some
technical hindrance then it has to be mentioned in log book. Likewise sometimes
producer cancels the program as if he wants to make some changes in that. Sometimes
the producer use fillers between the gaps of the programs. These all are mentioned
in the log book.
9. On-air warning
light
Light indicates that a program is being broadcast/on-air
10. Editing
Editing has to be done for both speech and music. For this
we use editing software nowadays. Another method is done by dubbing or copying,
it took place through reel to reel.
Editing is done to :
I. Remove the unnecessary material
II.
To enhance the quality of sound
III.
To add sound effects
IV.
For inserting actualities
V.
To compile the recording for certain time
duration.
