Low Cost Laboratory Environment for the Use of Optical Methods for Transmission of Audio Signals

In this paper we will discuss the possibilities of transmitting audio signals through optical and optoacoustic methods. An analysis of existing methods and the advantages of transmitting audio signals through optical methods will be made. A model of a Li-Fi system for transmitting audio signals and building one with a minimum number of electrical elements is considered. This is in order to implement the system presented in the laboratory sessions in front of students, the opportunity to build such systems from them as a practical exercise and the consideration of the possibilities for transmitting audio signals through optical methods.
