Abstract
A visible light audio system is operable to enable free space optical communication of audio signals via transmission of modulated light intensity at a light source to a photo diode being operably engaged with a demodulator and audio output device. Embodiments of the visible light audio system may be utilized, for example, in commercial, residential, or church buildings to transmit audio signals to occupants via the overhead lighting of the building. Embodiments of the present disclosure may be utilized in any commercial application where line of sight transmission of an audio signal is required or beneficial for occupants of an interior structure to receive a location-specific audio message.
