I. How They Work.
A microphone is an example of a transducer, a device that changes information from one form to another. Sound information exists as patterns of air pressure; the microphone changes this information into patterns of electric current. The recording engineer is interested in the accuracy of this transformation, a concept he thinks of as fidelity. A variety of mechanical techniques can be used in building microphones. The two most commonly encountered in recording studios are the magneto-dynamic and the variable condenser designs.
THE DYNAMIC MICROPHONE.
In the magneto-dynamic, commonly called dynamic, microphone, sound waves cause movement of a th
