Abstract

A cognitive load reduction system comprises a sound source position decision engine configured to receive one or more audio signals from a corresponding one or more signal generators, wherein the sound source position decision engine is further configured to identify two or more discrete sound sources within at least one of the one or more audio signals. The cognitive load reduction system further comprises an environmental assessment engine configured to assess environmental sounds within an environment. The cognitive load reduction system further comprises a sound location engine configured to output one or more audio signals configured to cause a plurality of speakers to change a perceived location of at least one of the discrete sound sources within the environment responsive to locations of other sounds within the environment.

Claims

1. A cognitive load reduction system, comprising:

a sound source position decision engine configured to receive one or more audio signals from a corresponding one or more signal generators, the sound source position decision engine configured to identify two or more discrete sound sources within at least one of the one or more audio signals;

an environmental assessment engine configured to assess environmental sounds within an environment; and

a sound location engine configured to output one or more audio signals configured to cause a plurality of speakers to change a perceived location of at least one of the discrete sound sources within the environment responsive to locations of other sounds within the environment.

2. The cognitive load reduction system of claim 1, wherein the one of one or more audio signals is a mobile communication stream and the two or more discrete sound sources are discrete voices in the mobile communication stream.

3. The cognitive load reduction system of claim 2, wherein the sound location engine is configured to spatially separate a perceived location of each of the discrete voices in the mobile communication stream.

4. The cognitive load reduction system of claim 3, wherein the sound source position decision engine is configured to determine a prioritization of the discrete voices based on an activity level of each of the discrete voices within the mobile communication stream, and wherein the sound location engine is configured to spatially separate based on the prioritization.

5. The cognitive load reduction system of claim 1, wherein the sound location engine is configured to adjust relative amplitudes of the plurality of speakers to change the perceived location of the one of the discrete sound sources within the environment.

6. The cognitive load reduction system of claim 1, wherein the sound location engine is configured to adjust relative delays of the plurality of speakers to change the perceived location of the one of the discrete sound sources within the environment.

7. The cognitive load reduction system of claim 1, wherein the sound location engine is configured to cause the plurality of speakers to change the perceived location of at least one of the discrete sound sources within the environment further responsive to content of the one or more audio signals.

8. The cognitive load reduction system of claim 1, wherein the sound location engine is configured to cause the plurality of speakers to change the perceived location of at least one of the discrete sound sources within the environment further responsive to user feedback.

9. The cognitive load reduction system of claim 1, wherein the sound location engine is configured to determine weighting factors for one or more of the plurality of speakers to change the perceived location of the one of the discrete sound sources within the environment.

10. The cognitive load reduction system of claim 1, wherein the environment is a vehicle cabin.

11. The cognitive load reduction system of claim 10, wherein the sound location engine is configured to output one or more audio signals configured to cause the plurality of speakers to change the perceived location of at least one of the discrete sound sources within the environment further responsive to locations of sounds from one or more passengers in the vehicle cabin.

12. The cognitive load reduction system of claim 1, wherein the sound location engine is configured to cause the plurality of speakers to change the perceived location of at least one of the discrete sound sources within the environment further responsive to a predetermined prioritization of the one or more audio signals.

13. A vehicle cognitive load reduction system, comprising:

a sound source position decision engine configured to receive one or more audio signals from a corresponding one or more vehicle components; and

a sound location engine configured to output one or more audio signals configured to cause a plurality of speakers within a vehicle cabin to set a perceived location of different ones of the one or more vehicle components at different locations within the vehicle cabin.

14. The vehicle cognitive load reduction system of claim 13, wherein a perceived location of an audio signal is set based on a predetermined prioritization of the audio signal with respect to the other audio signals.

15. The vehicle cognitive load reduction system of claim 13, wherein the one or more vehicle components includes a notification system.

16. The vehicle cognitive load reduction system of claim 13, wherein the one or more vehicle components includes a communication system.

17. The vehicle cognitive load reduction system of claim 13, wherein the one or more vehicle components includes an entertainment system.

18. The vehicle cognitive load reduction system of claim 13, wherein the one or more vehicle components includes a navigation system.

19. The vehicle cognitive load reduction system of claim 13, wherein the one or more vehicle components includes a text-to-speech system.

20. In a vehicle cabin, a method of prioritizing sound for a driver, the method comprising:

using a plurality of speakers within the vehicle cabin to place a perceived location of a first of a two or more sound sources at a first location within the vehicle cabin; and

using the plurality of speakers to place a perceived location of a second of the two or more sound sources at a second location within the vehicle cabin, the first location and the second location being spatially separated from one another and from any of the plurality of speakers.
