Abstract

A sound management system for use by a user located within an environment includes a memory device for storing a selection of sounds. The sounds can be music and/or various “colors” of noise (e.g., white, pink, and brown). A controller is used to select one particular stored sound based on a measured biological condition of the user, such as stress or fatigue, or an environmental condition of the environment, such as ambient noise. According to one embodiment, the system is used in conjunction with a sit/stand desk and the sound selection is made in response to changes in the desk height. The selected sound is selected to help abate or mitigate distracting sounds in the environment, such as people talking. The selected sounds are played to the user through headphones worn by the user, or through nearby speakers.

Claims

1. A sound management system for use with a height adjustable desk that can be displaced between first and second configurations with a work surface at a standing height and a sitting height, respectively, the system for use with sensor devices including at least a first sensor, the sound management system comprising:

a memory device for storing a plurality of sounds wherein each sound is audibly different than the other sounds in the plurality of sounds, each sound associated in the memory device with a specific configuration of the height adjustable desk; and

a controller linkable to a speaker, the controller controlling the speaker to generate a series of selected sounds of the plurality of sounds substantially persistently while a user occupies the height adjustable desk during a use period, the controller further programmed to receive an input from at least a first sensor device that indicates a current height of the height adjustable desk, the controller selecting different sounds of the plurality of sounds during different sub-periods of the use period based on at least the current height of the height adjustable desk, the controller automatically transitioning from one selected sound to a next selected sound when the configuration of the height adjustable desk changes.

2. The system of claim 1 further including at least a second sensor device for sensing at least a second condition associated with the height adjustable desk, the controller selecting different sounds during different sub-periods of the use period based on both the second condition and the current configuration of the height adjustable desk.

3. The system of claim 2 wherein the second sensor device senses user activity and the user activity is related to a software program currently being used at the height adjustable desk by the user that occupies the height adjustable desk.

4. The system of claim 2 wherein the second sensor device senses user activity and the user activity is related to activity level of the user that occupies the height adjustable desk.

5. The system of claim 2 wherein the second sensor device senses at least one biological condition of the user at the height adjustable desk.

6. The system of claim 5 wherein the biological condition is a level of user fatigue.

7. The system of claim 5 wherein the biological condition is a level of user stress.

8. The system of claim 2 wherein the second condition is not a biological condition of the user, the controller selecting different sounds during different sub-periods of the use period based on both the current configuration and the second condition.

9. The system of claim 8 wherein the second condition includes an environmental condition proximate the height adjustable desk.

10. The system of claim 1 further including at least a second sensor device for sensing at least a second condition associated with the height adjustable desk, wherein the second condition includes at least some statistic related to the height of the work surface.

11. The system of claim 10 wherein the statistic related to the height of the work surface includes the duration of time that the work surface remains at a current height.

12. The system of claim 2 wherein the second condition includes posture of a user using the height adjustable desk.

13. The system of claim 1 further including at least a second sensor device for sensing at least a first environmental condition proximate the height adjustable desk, the controller tuning at least a first characteristic of the selected sound as a function of the first environmental condition.

14. The system of claim 13 wherein the first environmental condition includes ambient sound proximate the height adjustable desk, the controller tuning at least a first characteristic of the selected sound to at least partially mask the ambient sound proximate the height adjustable desk.

15. The system of claim 14 wherein the first characteristic includes volume.

16. The system of claim 1 wherein the at least a first sensor and the speaker are integrated into the height adjustable desk.

17. A sound management system for use with a height adjustable desk that can be displaced between first and second configurations with a work surface at a standing height and a sitting height, respectively, the system for use with sensor devices including at least a first sensor device and a second sensor device, the sound management system comprising:

a memory device for storing a plurality of sound tracks wherein each sound track is audibly different than the other sound tracks in the plurality of sound tracks, each sound track associated in the memory device with at least one combination of a specific user activity and work surface height; and

a controller linkable to a speaker, the controller controlling the speaker to generate a series of selected sound tracks of the plurality of sound tracks substantially persistently while a user occupies the height adjustable desk during a use period, the controller further programmed to receive inputs from at least the first sensor device that indicates a current activity of a user that occupies the height adjustable desk and the second sensor device that indicates work surface height, the controller automatically selecting and broadcasting different sound tracks of the plurality of sound tracks during different sub-periods of the use period based on at least the current activity of the user occupying the height adjustable desk and the current work surface height.

18. The system of claim 17 wherein the first sensor device indicates a current activity level of the user that occupies the height adjustable desk and wherein the controller selects different sound tracks based at least in part on the current activity level of the user that occupies the height adjustable desk.

19. The system of claim 18 wherein the second sensor device senses at least a first environmental condition proximate the height adjustable desk, the controller tuning at least a first characteristic of each selected sound track as a function of the first environmental condition.

20. The system of claim 19 wherein the first environmental condition includes ambient sound proximate the height adjustable desk, the controller tuning at least a first characteristic of the selected sound track to at least partially mask the ambient sound proximate the height adjustable desk.

21. A sound management system for use with a height adjustable desk that can be displaced between first and second configurations with a work surface at a standing height and a sitting height, respectively, the system for use with sensor devices including at least a first sensor device and a second sensor device, the sound management system comprising:

a memory device for storing a plurality of sound tracks wherein each sound track is audibly different than the other sound tracks in the plurality of sound tracks, each sound track associated in the memory device with at least one combination of a specific user activity and work surface height; and

a controller linkable to a speaker, the controller controlling the speaker to generate a series of selected sound tracks of the plurality of sound tracks substantially persistently while a user occupies the height adjustable desk during a use period, the controller further programmed to receive inputs from at least the first sensor device that indicates a measured biological condition of a user that occupies the height adjustable desk and the second sensor device that indicates work surface height, the controller automatically selecting different sound tracks of the plurality of sound tracks during different sub-periods of the use period based on at least the measured biological condition of the user occupying the height adjustable desk and the current work surface height.

22.
