1. An augmented reality-based acoustic analysis method, comprising:
identifying structural elements of a space;
determining structural parameters of the structural elements and a structural parameter of the space;
displaying, by an augmented reality (AR) device and in response to a user input to the AR device selecting and placing a virtual lighting fixture model at a particular location of the space as displayed in a viewport of the AR device, the virtual lighting fixture model on the viewport of the AR device, wherein the virtual lighting fixture model is overlaid on a real-time image of the space; and
determining, by the AR device, a sound reverberation time of the space based on at least a sound absorption parameter associated with the virtual lighting fixture model and a sound absorption parameter of the space determined based on the structural parameters of the structural elements and the structural parameter of the space.
