Abstract

An apparatus including a housing forming a protective head cover and a hearing protection mechanism coupled to the housing is defined. The apparatus further includes an attachment mechanism coupled to the housing and the attachment mechanism is to connect the housing to an external air supply.

Claims

1. An apparatus comprising:

a housing forming a protective head cover;

a hearing protection mechanism coupled to the housing; and

an attachment mechanism coupled to the housing, the attachment mechanism to connect the housing to an external air supply.

2. The apparatus of claim 1, further comprising:

an adjustment mechanism to adjust a placement of the hearing protection mechanism within the protective head cover.

3. The apparatus of claim 1, wherein the protective head cover defines an inbound space to receive positive atmospheric pressure from the external air supply.

4. The apparatus of claim 1, wherein the hearing protection mechanism comprises:

a noise isolation mechanism.

5. The apparatus of claim 1, wherein the hearing protection mechanism comprises:

an active noise cancelling mechanism.

6. The apparatus of claim 1, wherein the hearing protection mechanism comprises:

a speaker mechanism to output audio signals from an audio source.

7. The apparatus of claim 1, wherein the hearing protection mechanism comprises:

a port through which to receive an audio signal from an external source.

8. The apparatus of claim 1, wherein the hearing protection mechanism comprises:

a receiver to receive an audio signal wirelessly from an audio source.

9. The apparatus of claim 1, wherein the hearing protection mechanism has a noise cancellation range of up to 8,000 Hz.

10. The apparatus of claim 1, wherein the hearing protection mechanism comprises:

a foam member to cover an ear.

11. The apparatus of claim 11, wherein the hearing protection mechanism comprises:

an activation mechanism to activate the hearing protection mechanism.

12. An apparatus comprising:

a mounting mechanism to attach the apparatus to a protective head cover, the protective head cover coupled to an external air supply; and

a padding module coupled to the mounting mechanism, the padding module to dampen a sound level within the protective head cover.

13. The apparatus of claim 12, further comprising:

an adjustment mechanism to adjust a placement of the hearing protection mechanism within the protective head cover.

14. The apparatus of claim 12, wherein the protective head cover defines an inbound space to receive positive atmospheric pressure from the external air supply.

15. The apparatus of claim 12, wherein the padding module comprises:

a noise isolation mechanism.

16. The apparatus of claim 12, wherein the padding module comprises:

an active noise cancelling mechanism.

17. The apparatus of claim 12, wherein the padding module comprises:

a speaker mechanism to output audio signals from an audio source.

18. The apparatus of claim 12, wherein the padding module comprises:

a port through which to receive an audio signal from an external source.

19. The apparatus of claim 12, wherein the padding module has a noise cancellation range of up to 8,000 Hz.

20. The apparatus of claim 12, wherein the padding module comprises:

a foam member to cover an ear.
