Methods and systems for generating acoustic impulse responses

A system for generating an impulse response for a listening point in a room, the system comprising:

• a computer system having a processor coupled to a memory, the processor configured to:
• receive a 3D model of the room, the position of at least one sound source in the 3D model of the room, and acoustic properties of at least one boundary in the 3D model of the room;
• determine, using a wave-based solver, a wave-based impulse response of a wave-based propagation of an impulse emitted at the at least one sound source in the 3D model of the room and received at the listening point within a first acoustic frequency range;
• determine, using a geometrical acoustics-based solver, a geometrical impulse response of a ray-based propagation of an impulse emitted at the at least one sound source in the 3D model of the room and received at the listening point within a second acoustic frequency range;
• and
• generate the impulse response by merging the wave impulse response and the geometrical impulse response.
