Patent attributes
A set of earphones or other wearable or portable audio equipment may be configured to play relevant sound signals from a speaker provided within a cavity mounted about an ear of a user. The earphones may include one or more microphones for capturing acoustic energy within a vicinity of the earphones, or may be in communication with one or more external microphones. Where one or more of the microphones captures acoustic energy that includes a plurality of sound signals, the signals may be processed to identify one of the signals that is relevant to the user. The relevant signal may be reconstructed and amplified from the speaker, and all other signals may be ignored or attenuated. The signals may be further processed to determine any additional information regarding sources of the signals, including whether such signals are within a vicinity of the user, or may pose a risk to the user.
