TEKS 11Bv Understanding various
microphones based upon type and pickup
patterns.

2. Microphones
 Microphone (mike or mic): A device that
converts sound waves into electrical
modulations for recording.

3. Sound Converting Systems
 There are three major types of sound-converting
systems which are used to
classify microphones.
 Dynamic
 Condenser
 Ribbon

4. Dynamic Microphones
 These are the most rugged.
 They can be used close to the sound
source and still withstand high sound
levels without damage to the
microphone or sound distortion.
 They can also withstand fairly extreme
temperatures so they are an ideal
outdoor microphone.

5. Condenser Microphones
 Much more sensitive to physical shock,
temperature change, and distortion
than dynamic microphones.
 Usually produce higher quality sound
when used at greater distances from
sound source.
 Can be used outdoors under certain
circumstances.

6. Ribbon Microphones
 Similar in sensitivity and quality to the
condenser microphones.
 Produce a warmer sound, frequently
preferred by singers.
 Strictly for indoor use.

7. Pickup Pattern
 A pickup pattern is the directions (in
three dimensions) in which a
microphone is most sensitive to sounds.

8. Omnidirectional
 Omnidirectional microphones have a
pickup pattern in which the microphone
can pick up sounds equally well from all
directions.

9. Unidirectional
 Unidirectional microphones have a
pickup pattern in which the microphone
can pick up sounds better from the
front than from the sides or back.
