Description

This course begins by explaining the concept of acoustical transduction and psychoacoustic transduction. You will learn about electrodynamic, reciprocal and electrostatic transducers. You will also learn about transducers as an electric network. You will be introduced to the transduction coefficient and acoustical propagation. You will also be introduced to mathematical expressions which are relevant to the models discussed.

The course then explains the significance, types as well as the mathematical expressions of reciprocal transducers. You will learn about antireciprocal transducers and a very important principle known as mechanical duality. You will also learn about the mathematical derivations for antireciprocal transducers. You will also be introduced to the transformation factor and the effects of mechanical impedance from the diaphragm.

Furthermore, you will be introduced to the requirements for professional microphones including frequency response, directivity and sensitivity. You will learn about the various types of microphones as well as their important features. You will also learn about the electronically standard sensitivity defined by the Electronic Industries Association (EIA). You will be introduced to the functional requirements of a loudspeaker and the construction details of a coil loudspeaker.
