Abstract
Systems, devices and methods for communication include an ear canal microphone configured for placement in the ear canal to detect high frequency sound localization cues. An external microphone positioned away from the ear canal detects low frequency sound, such that feedback is substantially reduced. The canal microphone and the external microphone are coupled to a transducer, such that the user perceives sound from the external microphone and the canal microphone with high frequency localization cues and decreased feedback. Wireless circuitry is configured to connect to many devices with a wireless protocol, such that the user receives and transmits audio signals. A bone conduction sensor detects near-end speech of the user for transmission with the wireless circuitry in noisy environment. Noise cancellation of background sounds near the user improves the user's hearing of desired sounds.
