receiving a sensor input associated with the first vehicle; identifying a soundscape element based on the selected simulated soundscape; determining a sound corresponding to the soundscape element based on the sensor input; determining a location within the vehicle cabin of the sound based on the selected simulated soundscape; and causing playback of the sound within the vehicle cabin based on the location. ### Claim 2 (depends on 1) The computer-implemented method of claim 1, wherein the simulated soundscape comprises a soundscape associated with a second vehicle that is different from the first vehicle. ### Claim 3 (depends on 2) The computer-implemented method of claim 2, wherein the second vehicle comprises a different powertrain than the first vehicle. ### Claim 4 (depends on 1) The computer-implemented method of claim 1, wherein the first vehicle comprises an electric powertrain and the simulated soundscape is associated with a combustion engine powertrain. ### Claim 5 (depends on 1) The computer-implemented method of claim 1, wherein the sensor input is associated with vehicle motion or vehicle acceleration of the first vehicle. ### Claim 6 (depends on 5) The computer-implemented method of claim 5, wherein the sensor input comprises a revolutions-per-minute (RPM) of one or more wheels of the first vehicle or a motor associated with the first vehicle. ### Claim 7 (depends on 5) The computer-implemented method of claim 5, wherein determining the sound corresponding to the soundscape element further comprises: determining a degree of vehicle motion or vehicle acceleration; and selecting the sound from a library of sounds associated with the selected simulated soundscape based on the degree or vehicle motion or vehicle acceleration. ### Claim 8 (depends on 1) The computer-implemented method of claim 1, wherein the sound comprises an engine sound, a sound caused by engagement with a road, or a transmission sound associated with a second vehicle. ### Claim 9 (depends on 1) The computer-implemented method of claim 1, further comprising causing vibration of a vehicle component based upon the sensor input. ### Claim 10 (depends on 9) The computer-implemented method of claim 9, wherein the vehicle component comprises one or more seats within the first vehicle. ### Claim 11 (depends on 1) The computer-implemented method of claim 1, wherein determining the location within the vehicle cabin of the sound based on the selected simulated soundscape comprises determining a location of a simulated vehicle sound relative to one or more occupants of the first vehicle. ### Claim 12 (depends on 10) The computer-implemented method of claim 10, wherein causing playback of the sound comprises causing the simulated vehicle sound to be played back by one or more speakers associated with the vehicle from a direction associated with the location of the simulated vehicle sound. ### Claim 13 One or more non-transitory computer-readable media storing instructions for reproducing a simulated soundscape within a first vehicle that, when executed by one or more processors, cause the one or more processors to perform the steps of: receiving selection of the simulated soundscape within a vehicle cabin associated with the first vehicle; receiving a sensor input associated with the first vehicle; identifying a soundscape element based on the selected simulated soundscape; determining a sound corresponding to the soundscape element based on the sensor input; determining a location within the vehicle cabin of the sound based on the selected simulated soundscape; and causing playback of the sound within the vehicle cabin based on the location. ### Claim 14 (depends on 13) The one or more non-transitory computer-readable media of claim 13, wherein the simulated soundscape comprises a soundscape associated with a second vehicle that has a different powertrain than the first vehicle. ### Claim 15 (depends on 13) The one or more non-transitory computer-readable media of claim 13, wherein the first vehicle comprises an electric powertrain and the simulated soundscape is associated with a combustion engine powertrain. ### Claim 16 (depends on 13) The one or more non-transitory computer-readable media of claim 13, wherein the sensor input is associated with vehicle motion or vehicle acceleration of the first vehicle. ### Claim 17 (depends on 13) The one or more non-transitory computer-readable media of claim 13, wherein the sound comprises an engine sound, a sound caused by engagement with a road, or a transmission sound associated with a second vehicle. ### Claim 18 (depends on 13) The one or more non-transitory computer-readable media of claim 13, further comprising causing vibration of a vehicle component based upon the sensor input, wherein the vibration is caused by activating a seat shaker within a seat within the first vehicle. ### Claim 19 (depends on 13) The one or more non-transitory computer-readable media of claim 13, wherein the simulated soundscape includes an exhaust sound associated with a combustion engine powertrain. ### Claim 20 A system comprising: a memory storing instructions for an audio enhancement application;
