TEKS 11Bv Understanding various microphones based upon type and pickup

patterns.

Microphones

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

Sound Converting Systems

There are three major types of sound-converting systems which are used to classify microphones.

Dynamic

Condenser

Ribbon

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.

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.

Ribbon Microphones

Similar in sensitivity and quality to the condenser microphones.

Produce a warmer sound, frequently preferred by singers.

Strictly for indoor use.

Pickup Pattern

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

Omnidirectional

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

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.
