Abstract
A headset generates an output audio signal to provide a virtual sound source for an object or virtual object by using a room impulse response generated by a simulation using a model of a room generated from image data. The headset may include processing circuitry that obtains the model of the room determined based on the image data. The image data includes depth image data from a depth camera assembly and color image data from a color camera. The model includes surfaces of the room and acoustic absorptions of the surfaces. The processing circuitry adjusts audio content presented by the headset based on a room impulse response determined based on one or more simulations of sound propagation between a target position of an object and a position of the headset within the room using the surfaces of the room and the acoustic absorptions of the surfaces.
