Auxiliary microphone and methods for improved hearing in smart glass applications

A headset, comprising:

• a first microphone mounted on the headset and configured to receive a first audio signal from a speaker;
• a second microphone remotely located from the headset and configured to receive a second audio signal from the speaker;
• a memory storing multiple instructions;
• and
• one or more processors configured to execute the instructions and cause the headset to:
• synchronize the first audio signal and the second audio signal;
• form an enhanced audio signal with the first audio signal and the second audio signal, wherein to form the enhanced audio signal, the one or more processors are configured to:
• identify a noise source in the second audio signal, and
• remove the noise source from the first audio signal;
• and
• provide the enhanced audio signal to a user of the headset.

A computer-implemented method, comprising:

• receiving, in a mobile device paired to an augmented reality headset worn by a user, a first audio signal from a first microphone mounted on the augmented reality headset;
• receiving, in the mobile device, a second audio signal from a second microphone remotely located from the augmented reality headset;
• providing the first audio signal and the second audio signal to a remote server;
• forming an enhanced audio signal with the first audio signal and the second audio signal, wherein forming the enhanced audio signal comprises:
• identifying a noise source in the second audio signal, and
• removing the noise source from the first audio signal;
• receiving, from the remote server, the enhanced audio signal;
• and
• providing the enhanced audio signal to the augmented reality headset, for the user.
