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 sit-stand desk including a height adjustable work surface, the sound management system comprising:

a memory device for storing a plurality of sounds including at least a first sound and a second sound, wherein the first sound is audibly different than the second sound; and

a controller for selecting at least one of the plurality of stored sounds as a selected sound based on at least a first input signal, the first input signal and the corresponding selected sound being generated at least in part as a function of a height of the sit-stand desk;

wherein said controller sends a command to a speaker to audibly generate said selected sound; and

wherein the speaker is controlled to generate the selected sound until some other measured condition occurs; and

wherein the controller selects the selected sound based on the first input signal and at least a second input signal that is different than the first input signal, the second input signal generated at least in part as a function of a change in a measured biological condition of a user and wherein said measured biological condition of said user is user-fatigue.

2. The sound management system of claim 1, wherein said user-fatigue is determined by calorie expenditure of recent physical activity of said user.

3. The sound management system of claim 1, wherein said first sound is one of music and random noise.

4. The sound management system of claim 1, wherein said second sound is one of music and random noise.

5. The sound management system of claim 1, wherein said first sound is a combination of music and random noise.

6. The sound management system of claim 1, wherein said speaker is a set of headphones worn by the user.

7. The sound management system of claim 1, wherein said speaker is built into said sit-stand desk.

8. The sound management system of claim 1 wherein

said controller is further configured to select one of the plurality of stored sounds as a selected sound in response to at least a first statistic related to the height of the work surface.

9. The sound management system of claim 8, wherein said first sound is one of music and random noise and said second sound is the other of music and random noise.

10. The system of claim 8 wherein the statistic related to height includes instantaneous height of the work surface.

11. The system of claim 8 wherein the statistic related to height includes duration of time that the work surface is at a current height.

12. The system of claim 8 wherein the statistic related to height includes frequency of work surface height adjustment.

13. The sound management system of claim 1 wherein the other measured condition includes a change in the height of the sit-stand desk.

14. The sound management system of claim 13 wherein the selected sound includes a sound type, the system further including at least one ambient condition sensor, the controller further controlling at least one characteristic of the sound type based on information from the ambient condition sensor.

15. The sound management system of claim 14 wherein the at least one characteristic includes at least one of volume, loudness, timbre, harmonics, rhythm and pitch.

16. A sound management system for use with a sit-stand desk including a height adjustable work surface, the sound management system comprising:

a memory device for storing a plurality of sounds including at least a first sound and a second sound, wherein the first sound is audibly different than the second sound; and

a controller for selecting at least one of the plurality of stored sounds as a selected sound based on at least a first input signal, the first input signal and the corresponding selected sound being generated at least in part as a function of a height of the sit-stand desk;

wherein said controller sends a command to a speaker to audibly generate said selected sound;

wherein the speaker is controlled to generate the selected sound until some other measured condition occurs; and

wherein the controller selects the selected sound based on the first input signal and at least a second input signal that is different than the first input signal, the second input signal generated at least in part as a function of a change in a measured biological condition of said user and wherein said measured biological condition of said user is user-stress.

17. The sound management system of claim 16, wherein said user-stress is determined by one of body temperature, blood pressure, and heart rate.

18. A sound management system for use with a sit-stand desk including a height adjustable work surface, the sound management system comprising:

a memory device for storing a plurality of sounds including at least a first sound and a second sound, wherein the first sound is audibly different than the second sound; and

a controller for selecting at least one of the plurality of stored sounds as a selected sound based on at least a first input signal, the first input signal and the corresponding selected sound being generated at least in part as a function of a height of the sit-stand desk;

wherein said controller sends a command to a speaker to audibly generate said selected sound; and

wherein the speaker is controlled to generate the selected sound until some other measured condition occurs; and

19. A sound management system for use in a work space, the sound management system comprising:

wherein said controller sends a command to a speaker to audibly generate said selected sound; and

wherein said first input signal is generated at least in part as a function of a change in a measured biological condition of a user and the second input signal is generated at least in part as a function of a measured non-biological condition is a sensed height of a height adjustable sit-stand desk;

wherein the speaker is controlled to generate the selected sound until some other measured condition occurs;

wherein the measured non-biological condition is a sensed height of a height adjustable sit-stand desk.

20. The sound management system of claim 19, wherein said measured biological condition is user fatigue.
