All microphones work in a similar way. They have a diaphragm (or a ribbon) that moves in response to changes in air pressure due to sound waves impinging on the diaphragm – similarly to how the diaphragm or ‘eardrum’ in the human ear responds to sound. The movement of this diaphragm, or ribbon, then produces a changing voltage, with a positive value (or amplitude) when the diaphragm moves one way and a negative value (or amplitude) when the diaphragm moves the opposite way. There are three main types of microphone to choose from – dynamic, ribbon, and condenser.
DYNAMIC MICS
With a so-called ‘dynamic’ microphone (the word ‘dynamic’ means changing or
