    Abstract: Disclosed herein, among other things, is a system for customizing a hearing assistance device for a wearer. According to various embodiments, data corresponding to the wearer's acoustic environment is logged using the hearing assistance device. In various embodiments, the hearing assistance device is fitted by an adaptive fitting process controlled by the wearer, the adaptive fitting process having access to the data logged by the hearing assistance device to customize settings of the hearing assistance device for the wearer. In an embodiment, data related to fitting the hearing assistance device is sent via a network connection to a location accessible by the wearer's audiologist and/or device manufacturer. The sent data is used to create an interactive database, and the database is used for fitting hearing assistance devices for one or more wearers, in various embodiments.

    Abstract: Systems, devices and methods are provided to switch between transmit and receive modes in wireless hearing aids. Various aspects of the present subject matter relate to a communication system. Various embodiments of the communication system include an antenna with a resonant circuit having an inductive coil connected to a tuning capacitor. The communication system includes means to selectively drive the resonant circuit during a transmit mode, and means to selectively receive an induced signal in the resonant circuit during a receive mode. The communication system further includes means to selectively include a frequency shift canceling component in the resonant circuit to provide a first resonance frequency in the resonant circuit in the transmit mode and a second resonance frequency in the resonant circuit in the receive mode such that the first resonance frequency and the second resonance frequency are approximately equal. Other aspects are provided herein.

    Abstract: This application relates to a system for fitting a hearing aid by testing th e hearing aid patient with a three-dimensional sound field having one or more localize d sound sources. In one embodiment, a signal processing system employing head-relate d transfer functions is used to produce audio signals that simulate a three- dimensional sound field when a sound source driven by such audio signals is coupled directly to one or both ears. By transmitting the audio signals produced by the signal processing system to the hearing aid by means of a wired or wireless connection, the hearing aid itself may be used as the sound source.

    Abstract: Method and apparatus for microphone matching for wearable directional hearin g assistance devices are provided. An embodiment includes a method for matchin g at least a first microphone to a second microphone, using a user's voice from the user' s mouth. The user's voice is processed as received by at least one microphone to determin e a frequency profile associated with voice of the user. Intervals are detected where the user is speaking using the frequency profile. Variations in microphone reception between the first microphone and the second microphone are adaptively canceled during the intervals and when the first microphone and second microphone are in relatively constant spatial position with respect to the user's mouth.
