Abstract

For managing a sound system, a method is disclosed that includes identifying a location for measuring sound, directing light from a light emitter to the location, determining a speckle pattern at the location based on data received from an optical interferometer, and adjusting a sound producer based on the determined speckle pattern.

Claims

1. An apparatus comprising:

a light emitter;

an optical interferometer;

a location module that identifies a location for measuring sound, the location module directing light from the light emitter to the location;

a detection module that determines a speckle pattern at the location based on data received by the optical interferometer; and

a sound module that adjusts a sound producer based on the determined speckle pattern.

2. The apparatus of claim 1, wherein the sound module adjusts two or more sound producers to balance a sound level measured at the location.

3. The apparatus of claim 1, wherein the location module determines the location by identifying a person at the location.

4. The apparatus of claim 1, wherein the sound module adjusts the sound producer in response to an event selected from the group consisting of a change in volume, beginning playback of media content, a change in one or more of the locations, a change in one or more sound producers, and a command from a user.

5. The apparatus of claim 1, wherein the sound module adjusts the sound producer with a modification selected from the group consisting of phase, volume, direction, and balance.

6. The apparatus of claim 1, wherein the sound module adjusts two or more sound producers operating as part of a sound system in a room for media presentations.

7. The apparatus of claim 1, wherein the sound module notifies a user in response to adjusting a sound producer outside a threshold range.

14. The method of claim 1, further comprising notifying a user in response to adjusting a sound producer outside a threshold range.

8. A method comprising:

identifying a location for measuring sound;

directing light from a light emitter to the location;

determining a speckle pattern at the location based on data received by an optical interferometer; and

adjusting a sound producer based on the determined speckle pattern.

9. The method of claim 8, further comprising adjusting two or more sound producers to balance a sound level measured at the location.

10. The method of claim 9, wherein the two or more sound producers operate as part of a sound system in a room for media presentations.

11. The method of claim 8, wherein the identifying is based on identifying a person at the location.

12. The method of claim 8, wherein adjusting the sound producer is in response to an event selected from the group consisting of a change in volume, beginning playback of media content, a change in one or more of the locations, a change in one or more sound producers, and a command from a user.

13. The method of claim 8, wherein adjusting the sound producer comprises adjusting the sound producer with a modification selected from the group consisting of phase, volume, direction, and balance.

15. A system comprising:

a light emitter;

an optical interferometer;

one or more sound producers;

a location module that identifies a location for measuring sound, the location module directing light from the light emitter to the location;

a detection module that determines a speckle pattern at the location based on data received by the optical interferometer; and

a sound module that adjusts one of the one or more sound producers based on the determined speckle pattern.

16. The system of claim 15, wherein the sound module adjusts two or more sound producers to balance a sound level measured at the location.

17. The system of claim 15, wherein the one or more sound producers operate as part of a sound system in a room for media presentations.

18. The system of claim 15, wherein the location module identifies the location based on identifying a person at the location.

19. The system of claim 15, wherein the adjusting module adjusts the one or more sound producers in response to an event selected from the group consisting of a change in volume, beginning playback of media content, a change in one or more of the locations, a change in one or more sound producers, and a command from a user.

20. The system of claim 15, wherein adjusting the sound producer comprises adjusting the sound producer with a modification selected from the group consisting of phase, volume, direction, and balance.
