Abstract

A method for selective sound field environment processing for one or more wireless earpieces, each of the one or more wireless earpieces including comprising a plurality of microphones is provided. The method includes receiving audio input of a sound field environment from the plurality of microphones of each of the one or more wireless earpieces, identifying background noise in the sound field environment, identifying audio from at least one sound source within the sound field environment, processing the audio input using one or more processors of at least one of the wireless earpieces to reduce the background noise and processing the audio input using one or more processors of the at least one of the wireless earpieces to enhance the audio from the at least one sound source within the sound field environment to provide processed audio, and transducing the processed audio at one or more speakers of the one or more wireless earpieces.

Claims

1. A method for selective sound field environment processing for one or more wireless earpieces, each of the one or more wireless earpieces comprising a plurality of microphones, the method comprising:

receiving audio input of a sound field environment from the plurality of microphones of each of the one or more wireless earpieces;

identifying background noise in the sound field environment;

identifying audio from at least one sound source within the sound field environment;

processing the audio input using one or more processors of at least one of the wireless earpieces to reduce the background noise and processing the audio input using one or more processors of the at least one of the wireless earpieces to enhance the audio from the at least one sound source within the sound field environment to provide processed audio;

transducing the processed audio at one or more speakers of the one or more wireless earpieces.

6. The method of claim 1 wherein the at least one sound source within the sound field environment is a machine.

7. The method of claim 6 further comprising receiving an input from a user of the one or more wireless earpieces wherein the input from the user specifies the machine as one of the least one sound source.

8. The method of claim 1 further comprising receiving an input from a user of the one or more wireless earpieces wherein the input from the user specifies the at least one sound source.

9. The method of claim 8 wherein the input from the user of the one or more wireless earpieces further specifies one or more processing parameters of the at least one sound source.

10. The method of claim 9 wherein the input from the user is voice input.

11. The method of claim 10 wherein the voice input comprises one or more keywords.

12. The method of claim 11 further comprising processing the audio input using one or more processors of the at least one of the wireless earpieces to attenuate audio greater than a particular intensity.

13. The method of claim 12 wherein each of the one or more wireless earpieces is an earbud.

14. The method of claim 1 further comprising calibrating the one or more wireless earpieces by isolating each of the at least one sound source and receiving user input identifying each of the at least one sound source.

2. The method of claim 2 wherein the processing the audio input using one or more processors of at least one of the wireless earpieces to reduce the background noise comprises active filtering.

3. The method of claim 2 wherein the at least one sound source within the sound field environment is a voice of a person.

4. The method of claim 3 wherein the one or more wireless earpieces are configured to identify the person based on the voice of the person.

5. The method of claim 4 further comprising receiving an input from a user of the one or more wireless earpieces wherein the input from the user specifies the person as one of the at least one sound source.

15. A wireless earpiece, comprising:

an earpiece housing;

a processor disposed within the earpiece housing;

a plurality of microphones operatively connected to the processor for receiving audio input of a sound field environment;

wherein the processor provides for executing instructions stored on a machine readable non-transitory medium for identifying background noise in the sound field environment, identifying audio from at least one sound source within the sound field environment, processing the audio input using the processor to reduce the background noise and processing the audio input using the processor to enhance the audio from the at least one sound source within the sound field environment to provide processed audio;

at least one speaker operatively connected to the processor for transducing the processed audio.

16. The wireless earpiece of claim 15 wherein the at least one sound source within the sound field environment is a voice of a person.

17. The method of claim 16 wherein the instructions further provide for identifying the person based on the voice of the person.

18. The method of claim 17 wherein the instructions further provide for comprising receiving an input from a user of the one or more wireless earpieces wherein the input from the user specifies the person as one of the at least one sound source.

19. The method of claim 18 wherein the input is voice input.
