Microphones have been used since the late 1800s to record sound. Describe what a microphone does. Explain how a dynamic and a condenser microphone works and identify the benefits of each.
A microphone, in essence, is a transducer which converts acoustic sound energy into electrical energy which can then be amplified or recorded. The sensitive transducer part of a microphone is called the element or capsule. There are many different types of microphones with different polar patterns for different purposes. Some of these polar patterns include ominidirectional, cardioid, hypercardioid and figure-of-8.
The two most common types of microphones are condenser and dynamic microphones. Dynamic or moving coil microphones work similarly to speakers, but in reverse. When sound enters the microphone, a diaphragm, which is positioned within the magnetic field of a metal coil, moves back and forth, vibrating. The vibrations interrupt the magnetic field and…
