MICROPHONETypes of microphone Its characteristics
Dynamic microphones
It is useful when the sound source is close and not too loud.
It is suitable for recording sound which pitch is
predominantly bass or mid-range, for example, the Pop
concert or rock n roll. It can be used to record sound
produced by musical instrument such as the percussion,
guitar and used in video camera. The output volume is low,
it is robust (tough) and its price is relatively cheaper as
compared to the other types of microphones.
Condenser microphones This type of microphone is quite sensitive and more fragile.
It is able to pick up high frequency signals and distant
sound. It is able produces louder output.
It is suitable to be used for studio recording and for
orchestra performance.
Unidirectional microphones Able to pick up sound from one direction only. Normally it
receives sound signal from the front part of the microphone.
Its pickup pattern can either be cardioids and Hyper
cardioids. It is useful when we need to eliminate the noise
from the surrounding environment.
Bi-directional microphones It can pick up sound form the opposite direction, which is
ideal for dialogue or for meeting.
Omni directional microphones It picks up sound from all direction and is ideal when there
is only one microphone to be shared by many speakers. It
may also be hang from the ceiling to receive sound signals

PLANNING & PREPARATION
1. Identify the objectives and learning outcomes By referring to syllabus and standards, we can identify the objectives and standards, scopes of
the contents, the types of learning activities, and values which should be included in theaudio presentation.

and elaboration which may effectively capture the students attention, arousetheir interest and convey the essential massage successfully.
3. Obtain the information (The topic, skills, content)and the relevantresources (sound effects, background music, CDs, etc.)
4. Preparing the script
Clearly define the sequencing of the content, the relevant sound effects for aparticular scenario, when and how the background music should come in,when to pause, phrases which needed emphasis and alike.
The script is a guide for the producer, the talents as well as the productioncrews. It helps the team to visualize how to act out a scene, to pin point theappropriate time to dub in the background music and/ or the sound effectsand so on and so forth.
