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 processor;

a memory that stores code executable by the processor to;

identify a location for measuring sound and, direct light from the light emitter to the location;

determine a speckle pattern at the location based on data received by the optical interferometer;

compare the speckle pattern with a sound generated at a first sound producer;

adjust a sound producer based on the comparison of the determined speckle pattern and the sound generated at the first sound producer.

2. The apparatus of claim 1, further comprising code executable by the processor to adjust two or more sound producers to balance a sound level measured at the location.

3. The apparatus of claim 1, further comprising code executable by the processor to determine the location by identifying a person at the location.

4. The apparatus of claim 1, further comprising code executable by the processor to adjust 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, further comprising code executable by the processor to adjust the sound producer with a modification selected from the group consisting of phase, volume, direction, and balance.

6. The apparatus of claim 1, further comprising code executable by the processor to adjust two or more sound producers operating as part of a sound system in a room for media presentations.

7. The apparatus of claim 1, further comprising code executable by the processor to notify 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;

comparing the speckle pattern with a sound generated at a first sound producer;

adjusting a sound producer based on the comparison of the determined speckle pattern and the sound generated at the first sound producer.

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.

14. The method of claim 8, further comprising notifying a user in response to adjusting a sound producer outside a threshold range.

15. A system comprising:

a light emitter;

an optical interferometer;

one or more sound producers;

a processor;

a memory that stores code executable by the processor to;

identify a location for measuring sound and, direct light from the light emitter to the location;

determine a speckle pattern at the location based on data received by the optical interferometer;

compare the speckle pattern with a sound generated at at least one of the one or more sound producers;

adjust one of the one or more sound producers based on the comparison of the determined speckle pattern and the sound generated at the sound producer.

16. The system of claim 15, further comprising code executable by the processor to adjust 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, further comprising code executable by the processor to identify the location based on identifying a person at the location.

19. The system of claim 15, further comprising code executable by the processor to adjust 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, further comprising code executable by the processor to adjust the sound producer with a modification selected from the group consisting of phase, volume, direction, and balance.
