Abstract

A multichannel acoustic system (MAS) comprises an arrangement of microphones, loudspeakers, and filters along with a multichannel acoustic processor (MAP) and other components to together provide and enhance the auditory experience of persons in a shared acoustic space such as, for example, the driver and other passengers in an automobile. Driver-specific features such as navigation and auditory feedback cues are described, as individual auditory customizations and collective communications both within the shared acoustic space as well as with other individuals not located in the space via enhanced conference call facilities.

First claim

What is claimed is:

1. A method for enhancing an auditory experience in a shared acoustic space comprising a plurality of zones, the method comprising:
receiving, at a plurality of microphones distributed throughout the shared acoustic space, sound signals substantially originating from the plurality of zones;
filtering, at a plurality of adaptable sound filters, audio data corresponding to the sound signals received at the plurality of microphones to cancel at least one of an echo signal or a feedback signal to generate filtered audio data; and
providing a conference call facility configured to generate, based on the filtered audio data, output data associated with a multi-dimensional acoustic effect to simulate, at a remote device positioned external to the shared acoustic space, a virtual positioning of one or more occupants of the shared acoustic space, wherein the output data indicates a virtual position of an occupant of the one or more occupants, the virtual position determined based on an identity of the occupant.

2. The method of claim 1 , wherein the conference call facility is provided by a mobile communication device operationally coupled to a multichannel acoustic system via a mobile communication interface of the mobile communication device, and further comprising receiving a biometric identifier corresponding to the occupant, wherein the identity of the occupant is determined based on the biometric identifier.

3. The method of claim 2 , wherein the biometric identifier comprises a voice of the occupant, wherein a second virtual position of a second occupant of the one or more occupants is based on a second identity of the second occupant, wherein the virtual positioning of the one or more occupants corresponds to acoustically simulating that the one or more occupants are positioned around a table, and further comprising providing an interface capable of operationally coupling a portable device located in each zone of the plurality of zones to the multichannel acoustic system.

4. The method of claim 2 , wherein the shared acoustic space comprises an interior passenger compartment of a transportation vehicle for persons, wherein the multichannel acoustic system is configured to identify and authenticate at least one passenger of the transportation vehicle, and wherein the conference facility is further configured to generate a second multi-dimensional acoustic effect that simulates a virtual positioning within the shared acoustic space of a conference call participant located external to the shared acoustic space such that the occupant perceives the conference call participant to be positioned at a particular location within the shared acoustic space.

5. The method of claim 1 , further comprising:
receiving a biometric identifier corresponding to the occupant;
determining the identity of the occupant based on the biometric identifier;
determining the virtual position of the occupant based on the identity of the occupant,
wherein the biometric identifier comprises a voice of the occupant, an image of the occupant, or a weight of the occupant; and

transmitting the output data to the remote device.

6. A multichannel acoustic system for enhancing an auditory experience in a shared acoustic space comprising a plurality of zones, the system comprising:
a plurality of loudspeakers located within the shared acoustic space;
a receiver coupled to a plurality of microphones and distributed throughout the shared acoustic space, the plurality of microphones configured to receive sound signals substantially originating from the plurality of zones;
a plurality of adaptable sound filters configured to generate filtered audio data by canceling at least one of an echo signal or a feedback signal of the audio data corresponding to the sound signals received via the plurality of microphones; and
a conference call facility configured to generate, based on the filtered audio data, output data associated with a multi-dimensional acoustic effect to simulate, at a remote device positioned external to the shared acoustic space, a virtual positioning of one or more occupants of the shared acoustic space, wherein the output data indicates a virtual position of an occupant of the one or more occupants, the virtual position determined based on an identity of the occupant.

7. The multichannel acoustic system of claim 6 , wherein the conference call facility comprises a mobile communication device operationally coupled to the multichannel acoustic system via a mobile communication interface of the mobile communication device, and further comprising an interface configured to receive a biometric identifier corresponding to the occupant.

8. The multichannel acoustic system of claim 6 , wherein the conference call facility includes an interface capable of operationally coupling a portable device located in each zone of the plurality of zones to the multichannel acoustic system.

9. The multichannel acoustic system of claim 6 , wherein the shared acoustic space comprises an interior passenger compartment of a transportation vehicle, and further comprising at least one sensor configured to receive an input, wherein the plurality of loudspeakers are positioned within the shared acoustic space and configured to generate a sound based on the input, wherein the sound corresponds to a warning, and wherein a quantity and a position of the plurality of loudspeakers at which the sound is generated is based on an identified hazard corresponding to the warning.

10. The multichannel acoustic system of claim 6 , wherein the plurality of loudspeakers is configured to provide navigation information to a driver of a vehicle, the navigation information including a directional context indicative of a direction of the navigation information.

11. An apparatus for enhancing an auditory experience in a shared acoustic space comprising a plurality of zones, the apparatus comprising:
means for receiving via a plurality of microphones distributed throughout the shared acoustic space, sound signals substantially originating from the plurality of zones;
means for filtering, at a plurality of adaptable sound filters, audio data corresponding to the sound signals received via the plurality of microphones to generate filtered audio data by canceling at least one of an echo signal or a feedback signal; and
means for providing a conference call facility that is configured to generate, based on the filtered audio data, output data associated with a multi-dimensional acoustic effect to simulate, at a remote device positioned external to the shared acoustic space, a virtual positioning of one or more occupants of the shared acoustic space, wherein the output data indicates a virtual position of an occupant of the one or more occupants, the virtual position determined based on an identity of the occupant.

12. The apparatus claim 11 , wherein the means for providing the conference call facility comprises a mobile communication device operationally coupled to a multichannel acoustic apparatus via a mobile communication interface of the mobile communication device, and, further comprising means for receiving a biometric identifier corresponding to the occupant, wherein the identity of the occupant is determined based on the biometric identifier.

13. The apparatus of claim 11 , further comprising means for operationally coupling a portable device located in each zone of the plurality of zones to a multichannel acoustic system.

14. The apparatus of claim 11 , further comprising means for authenticating at least one person associated with a transportation vehicle.
