Abstract

A headphone with adjustable speaker drivers and a microphone can be used to determine and adjust sound pressure levels. The speaker drivers can be adjusted manually or wirelessly via a mobile device with a wireless connection to the headphone. Processing of audio and microphone data via the headphone can also be used to help determine and adjust the sound pressure levels.

Claims

1. A system, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

receiving speaker driver position data representing a first speaker driver position associated with a headphone;

determining a sound pressure level based on audio signal data representing an audio signal and microphone signal data representing a microphone signal of the headphone; and

in response to receiving, from a mobile device, preference data representing a preference for a second speaker driver position, adjusting the second speaker driver position.

2. The system of claim 1, wherein the mobile device comprises an interface configured to receive an input of the preference data.

3. The system of claim 2, wherein the interface is further configured to display a graphical representation of multi-band frequency sound pressure location data representing a multi-band frequency applicable to operation of the headphone.

4. The system of claim 2, wherein the interface is further configured to display a graphical representation of overall band frequency sound pressure location data representing an overall band frequency applicable to operation of the headphone.

5. The system of claim 2, wherein the interface comprises a frequency band selector configured to adjust a frequency band applicable to operation of the headphone.

6. The system of claim 2, wherein the interface is configured to compress a frequency band applicable to operation of the headphone.

7. A method, comprising:

receiving, by a device comprising a processor, first speaker driver position data representing a first speaker driver position associated with a headphone;

based on audio signal data representing an audio signal and microphone signal data representing a microphone signal of the headphone, determining, by the device, a sound pressure level; and

in response to receiving instruction data representing an instruction to be executed for a second speaker driver position associated with the headphone, adjusting, by the device, the second speaker driver position.

8. The method of claim 7, wherein the first speaker driver position data is received from a mobile device.

9. The method of claim 7, wherein the instruction data is received from a mobile device.

10. The method of claim 9, wherein an interface of the mobile device is configured to display a graphical representation of overall band frequency sound pressure location data representing an overall band frequency applicable to operation of the headphone.

11. The method of claim 7, wherein the adjusting the second speaker driver position is based on manual input received by the headphone.

12. The method of claim 7, further comprising:

calibrating, by the device, the sound pressure level between a microphone and the first speaker driver position based on the audio signal data and the microphone data.

13. The method of claim 7, further comprising:

sending, by the device, warning data representative of a warning signal in response to a condition related to the sound pressure level being satisfied.

14. The method of claim 13, wherein the condition is based on a critical hearing level.

15. The method of claim 7, further comprising:

storing, by the device, sound pressure level data representing the sound pressure level in a memory accessible to the device.

16. A computer readable storage device having executable instructions stored thereon that, in response to execution, cause a system comprising a processor to perform operations, comprising:

receiving speaker driver position data representing a first speaker driver position associated with a headphone;

based on audio signal data representing an audio signal and microphone signal data representing a microphone signal of the headphone, determining a sound pressure level; and

in response to receiving preference data representing a preference for a second speaker driver position, adjusting a speaker driver from the first speaker driver position to the second speaker driver position.

17. The computer readable storage device of claim 16, further comprising:

compressing a first amplitude signal to satisfy a condition associated with the sound pressure level.

18. The computer readable storage device of claim 17, wherein the condition associated with the sound pressure level is based on a noise level.

19. The computer readable storage device of claim 16, further comprising:

facilitating displaying sound pressure level data, on a mobile device, representative of the sound pressure level of the headphone.

20. The computer readable storage device of claim 16, further comprising:

determining a noise level by averaging a first weight of a first amplitude signal with a second weight of a second amplitude signal.
