摘要： Systems and techniques are provided for processing audio data. A process can include obtaining first audio data from a first microphone in a first direction, and second audio data from a second microphone in a second direction. A directional audio signal can be generated, comprising a weighted sum of an omni-directional signal corresponding to the first audio data and a bi-directional difference signal corresponding to the first audio data and the second audio data. A constructed noise reference can be generated based on a difference between the omni-directional signal and the bi-directional difference signal. Estimated noise information associated with one or more of the first microphone or the second microphone can be determined, based on the constructed noise reference.

摘要： Embodiments of the invention include a method of charging a rechargeable battery, the method comprising the steps of: detecting the presence of a rechargeable hearing aid in a hearing aid recharger; generating a unique random ID in the charger; transmitting the unique random ID to the hearing aid using an extremely low power protocol; demodulating the unique ID in the hearing aid; using the demodulated unique ID in a low power protocol to advertise the hearing aid on a network which includes the charger; associating the hearing aid to the charger when the charger which broadcast the unique ID receives that unique ID from a hearing aid using a wireless protocol; using the wireless protocol to communicate between the associated charging station and hearing aid; radiating power from the charger to the hearing aid; and ending the association when the hearing aid is removed from the charger.

摘要： An ear tip apparatus for use with a hearing device is provided and comprises a malleable structure. The malleable structure is sized and configured for placement in an ear canal of a user. The malleable structure is deformable to allow an adjustable venting of the ear canal, thereby minimizing the occlusion effect. Methodology for adjusting a degree of venting of the ear canal is also provided, including the automatic adjustments. Adjusting the degree of venting may be done in response to one or more of detected feedback or an environmental cue.

摘要： Hearing systems for both hearing impaired and normal hearing subjects comprise an input transducer and a separate output transducer. The input transducer will include a light source for generating a light signal in response to either ambient sound or an external electronic sound signal. The output transducer will comprise a light-responsive transducer component which is adapted to receive light from the input transducer. The output transducer component will vibrate in response to the light input and produce vibrations in a component of a subject's hearing transduction pathway, such as the tympanic membrane, a bone in the ossicular chain, or directly on the cochlea, in order to produce neural signals representative of the original sound.

摘要： Contact hearing devices for use with a wearable communication apparatus are disclosed to provide the user with an open ear canal to hear ambient sound and sound from an audio signal. The disclosed devices and systems have an advantage of providing sound to user from the audio signal, in many embodiments without creating sound that can be perceived by others. The contact hearing device can also be used to amplify ambient sound to provide a hearing assistance to users with diminished hearing. The wearable information apparatus can be configured to couple wirelessly to the contact transducer assembly, such that the wearable information apparatus can be removed while the contact transducer assembly remains placed on the user.
