Abstract
According to various embodiments, systems and methods for transmitting acoustic waves in a region aided by reflection from environmental objects. An arrangement of acoustically reflective surfaces in an environment of a target can be detected to generate an environmental acoustic propagation channel model. An acoustic radiation pattern for reflecting one or more acoustic waves off of one or more acoustically reflective surfaces in the arrangement of acoustically reflective surfaces towards the target can be identified. A coherent acoustic beamforming device can be controlled to perform coherent beamforming of an acoustic hologram based on the acoustic radiation pattern to generate the one or more acoustic waves for reflection towards the target off of the one or more acoustically reflective surfaces.
