摘要： A system configured to perform acoustic feedback control to enable a device to perform hearing enhancement while suppressing acoustic feedback. During hearing enhancement, the device may amplify environmental noise based on a unique hearing profile associated with the user, personalizing equalization settings, a dynamic range, and/or other characteristics to optimize playback audio for the user. The acoustic feedback control may include an acoustic feedback cancellation (AFC) component that uses an adaptive filter to estimate and cancel a feedback signal. In addition, the AFC component may perform entrainment prevention by detecting periodic signals and adjusting an adaptation rate of the adaptive filter accordingly. Separately, the device may selectively suppress acoustic feedback by detecting frequency bands representing acoustic feedback (e.g., squeal detection) and applying one or more notch filter(s) to suppress the selected frequency bands (e.g., squeal suppression).

摘要： An environmental sound loudspeaker comprises a system and/or method for capturing, processing, and immediately replaying the captured sounds. The loudspeaker comprises a loudspeaker driver, a signal processor, a first microphone and a second microphone positioned a distance d apart, diametrically opposite each other and equidistant relative to a center of the driver. The signal processor receives a first input signal from the first microphone and a second input signal from the second microphone, each input signal representing a recorded sound; determines an output signal based on the first and second input signals; optionally, manipulates or enhances the sound, and provides the output signal to the driver. The output signal comprises inverting the first input signal, combining the inverted first input signal with the second input signal, and amplifying the resulting signal to obtain a high-fidelity signal of environmental sounds captured by the first and/or second microphones.

摘要： Provided is an echo cancellation apparatus capable of calculating an acoustic coupling amount with high accuracy regardless of the magnitude of the near-end speaker component and without using a double talk detector. The echo cancellation apparatus cancels an echo included in a sound pickup signal picked up by a microphone placed at a near-end and includes an acoustic coupling amount calculation unit that updates and calculates an acoustic coupling amount estimated value of a component of a reproduction signal, which is a signal picked up by a microphone placed at a far-end included in the sound pickup signal, such that an update amount is decreased the greater a magnitude of a component other than an echo component is in the sound pickup signal; a gain calculation unit that calculates a gain coefficient on the basis of the acoustic coupling amount estimated value; and an integration unit that integrates the gain coefficient with the sound pickup signal and generates an echo cancellation signal.
