Abstract

An apparatus for hearing protection comprising: a body having coupling means, said coupling means configured to attach to a body part; a sound sensor disposed in said body, said sound sensor configured to sense ambient sound; a sound processor coupled to said sound sensor, said sound processor configured to receive a sound signal from said sound sensor and generate a sound indicator signal; an indicator coupled to said sound processor and disposed in said body, said indicator configured to indicate sound levels, said indicator including at least one of a visual display and a tactile indicator, wherein said visual display visually indicates levels of sound and said tactile indicator indicates levels of sound through tactile means.

Claims

1. An apparatus for hearing protection comprising:

a body having coupling means, said coupling means configured to attach to a body part;

a sound sensor disposed in said body, said sound sensor configured to sense ambient sound;

a sound processor coupled to said sound sensor, said sound processor configured to receive a sound signal from said sound sensor and generate a sound indicator signal; and

an indicator coupled to said sound processor and disposed in said body, said indicator configured to indicate sound levels, said indicator including at least one of a visual display and a tactile indicator, wherein said visual display visually indicates levels of sound, said tactile indicator indicates levels of sound through tactile means, and said sound levels comprise safe levels, caution levels and danger levels.

2. The apparatus of claim 1, wherein said coupling means is a band.

3. The apparatus of claim 1, wherein said body part is a wrist.

4. The apparatus of claim 1, wherein said body part is an arm.

5. The apparatus of claim 1, wherein said indicator indicates sound levels ranging from safe ambient levels to dangerous levels that can damage hearing.

6. The apparatus of claim 1, wherein said visual display comprises portions of varying color that correspond to said sound levels.

7. The apparatus of claim 1, wherein said visual display comprises portions of varying symbols that correspond to said sound levels.

8. The apparatus of claim 1, wherein said visual display corresponds to decibel levels of said sound sensed by said sound sensor.

9. The apparatus of claim 1, wherein said visual display is analog.

10. The apparatus of claim 1, wherein said visual display is digital.

11. The apparatus of claim 1, wherein said visual display is a combination of analog and digital.

12. The apparatus of claim 1, wherein said visual display comprises strobe lights.

13. The apparatus of claim 1, wherein said visual display comprises flashing lights.

14. The apparatus of claim 1, wherein said tactile indicator comprises a vibrator that creates a vibration sensation.

15. The apparatus of claim 14, wherein said vibrator increases the frequency of said vibration sensation as the sound level increases.

16. The apparatus of claim 1, wherein said tactile indicator comprises an electric shock.

17. The apparatus of claim 1, wherein said safe levels are from about 0 to about 90 decibels, said caution levels are from about 90 decibels to 110 decibels, and said danger levels are greater than about 110 decibels.

18. The apparatus of claim 1, wherein said visual display comprises color codes associated with said sound levels.

19. The apparatus of claim 18, wherein said color codes comprise green associated with said safe levels, yellow associated with said caution levels, and red associated with said danger levels.
