A head-worn acoustic device includes at least one acoustic transducer disposed such that, in a head-worn state, the transducer is in an open-ear configuration in which an ear canal of a user of the head-worn acoustic device is unobstructed. The acoustic device also includes at least one microphone configured to capture audio that is processed and played back through the transducer, and an amplifier circuit configured to process signals representing the audio captured using the microphone and generate driver signals for the transducer. The transducer and the microphone are disposed on the head-worn acoustic device such that, in the head-worn state, a lobe of a radiation pattern of the at least one acoustic transducer is directed towards the ear canal of the user, and the at least one microphone is positioned in an acoustic null in a radiation pattern of the at least one acoustic transducer.

Microphone placement in open ear hearing assistance devices

A wearable for capturing self-voice using a mixed sensor array, including a microphone generating a microphone signal and positioned to capture a user's voice; an accelerometer generating an accelerometer signal and positioned to capture the user's voice; and a controller receiving the microphone signal and the accelerometer signal and configured to generate a mixed output signal, wherein the mixed output signal comprises a microphone signal component and an accelerometer signal component, wherein a ratio of the microphone signal component and the accelerometer signal component is related to a value of a noise metric representing a magnitude of ambient noise.

Wearable mixed sensor array for self-voice capture

An audio system and method for generating improved augmented hearing effects in real-time. The system includes a wearable audio device arranged to obtain audio that includes a voice signal associated with a user and an environmental signal associated with other audio picked up by the wearable audio device that does not includes the user's voice. In some implementations, at least one processor of the wearable audio device is configured to isolate the voice signal from the environmental signal such that augmented hearing effects can be applied to the voice signal and/or the environmental signal, independently. In some implementations, augmented hearing effects are designated by a signal augmentation profile generated or stored in the wearable audio device such that the total time between receipt of the audio signal and the modifications and/or transformations to the respective audio signals does not exceed 100 ms.

Real-time augmented hearing platform

A system for masking audio signals includes a microphone for generating an ambient audio signal representing ambient noise, a speaker for rendering masking audio, and a processor in communication with the microphone and the speaker. The processor performs spectral analysis on the ambient audio signal from the microphone to determine a spectral envelope of the ambient noise, adjusts a frequency response of an optimizing filter based on the spectral envelope, applies the optimizing filter to a baseline masking waveform, producing an output waveform with relative spectral distribution matching the ambient noise, and provides the output waveform to the speaker.
