Abstract

Methods and apparatuses for addressing open space noise are disclosed. In one example, a method for masking open space noise includes outputting from a speaker a speaker sound corresponding to a flow of water, and displaying a water element system, the water element system generating a sound of flowing water.

Claims

1. A method for masking open space noise comprising:

outputting a noise masking sound comprising a first sound of flowing water from a plurality of speakers being distributed in an open space; and

reducing an adverse effect on a user hearing the first sound of flowing water from the plurality of speakers comprising displaying a water element system, the water element system generating a second sound of flowing water to mask open space noise, the second sound of flowing water combining with the first sound of flowing water in the open space.

2. The method of claim 1, wherein the water element system is a waterfall.

3. The method of claim 1, wherein the first sound of flowing water a recording of a natural flow of water or an electronically synthesized sound of flow of water.

4. The method of claim 1, wherein the first sound of flowing water has been optimized to mask open space noise.

5. The method of claim 1, wherein the water element system is a waterfall disposed in the open space, and the plurality of speakers include speakers disposed at varying distances from the waterfall, the method further comprising:

adjusting an output level of the first sound of flowing water at a speaker in the plurality of speakers based on a distance of the speaker from the waterfall.

6. The method of claim 1, further comprising outputting from the plurality of speakers a further noise masking sound comprising a pink noise.

7. The method of claim 6, wherein the first sound of flowing water is output at a sound level to mask the pink noise.

8. The method of claim 6, wherein the first sound of flowing water is optimized to mask a higher frequency open space noise than the pink noise.

9. A system for masking open space noise comprising:

a speaker arranged to output a speaker sound in an open space, the speaker sound comprising a sound corresponding to a flow of water and a noise configured to mask open space noise; and

a display of flowing water disposed in the open space arranged to reduce an adverse effect on a user hearing the speaker sound comprising the sound corresponding to the flow of water and the noise configured to mask open space noise.

10. The system of claim 9, wherein the speaker is one of a plurality of speakers which are disposed in a plenum above the open space and arranged to direct the speaker sound in a direction opposite the open space.

11. The system of claim 9, wherein the display of flowing water is arranged to be visible from any location within the open space.

12. The system of claim 9, wherein the display of flowing water comprises a floor-to-ceiling waterfall arranged to be visible from anywhere within the open space to reduce the adverse effect on the user hearing the speaker sound.

13. The system of claim 9, wherein the speaker is one of a plurality of speakers disposed at varying distances from the display of flowing water, wherein an output level of the speaker sound from the speaker is adjusted based on a distance of the speaker from the display of flowing water.

14. The system of claim 9, wherein the display of flowing water comprises a video recording of a visible flow of water shown on an electronic display screen.

15. A method for masking open space noise comprising:

outputting a first masking sound at a speaker to mask an open space noise;

outputting a second masking sound comprising a sound of flowing water at the speaker to mask the first masking sound and mask the open space noise; and

reducing an adverse effect on a user hearing the second masking sound comprising the sound of flowing water from the speaker comprising generating a flow of water, the flow of water emitting a water sound operable to mask the open space noise.

16. The method of claim 15, wherein the first masking sound is a pink noise and the second masking sound comprises an audio recording of the sound of flowing water.

17. The method of claim 15, wherein the first masking sound is a pink noise and the second masking sound comprises sounds associated with a nature environment, the nature environment comprising a rainforest.

18. The method of claim 15, wherein the flow of water comprises a floor-to-ceiling waterfall arranged to be visible from anywhere within an open space to reduce the adverse effect on the user hearing the second masking sound.

19. The method of claim 15, wherein a first masking sound level of the first masking sound or a second masking sound level of the second masking sound are changed as a function of time.
