Microphones: Theory and Design

This lecture introduces the theory and design of microphones, covering topics such as sensitivity, directivity, mechanical and electrical specifications, and external influences. It explains the four categories of microphones and discusses sensitivity in free field, directivity patterns, and diffraction effects. The lecture also explores properties like reverberant field reduction, diffraction, sensitivity in pressure, and microphone-equipment matching. Additionally, it delves into nominal values, proximity microphones, and other specifications including impedance ranges and output connectors.
