摘要： The present subject matter provides method and apparatus for hearing assistance devices, and more particularly to a system for evaluating hearing assistance device settings using detected sound environment. Various examples of a hearing assistance device and method using actual use and hypothetical use logs are provided. Such logs provide a dispenser or audiologist the ability to see how a device is operating with actual settings and how the device would have operated had hypothetical settings been used instead. In various examples, the system allows for collection of statistical information about actual and hypothetical use which can assist in parameter setting determinations for a specific user. The settings may be tailored to that user's commonly experienced sound environment. Wireless communications of usage logs is discussed. Additional method and apparatus can be found in the specification and as provided by the attached claims and their equivalents.

摘要： Embodiments of packet loss concealment for phone-to-hearing-aid streaming are generally described herein. A method for packet loss concealment can include receiving a first frame at a hearing assistance device, determining, at the hearing assistance device, that a second frame was not received within a predetermined time, and determining a first set of sequential samples that match the first frame. The method can include cross-fading the first frame and the first set of sequential samples to create a first cross-faded frame and extrapolating a third frame to replace the second frame using the first set of sequential samples and an autoregressive model.

摘要： Disclosed herein, among other things, are methods and apparatus for improved noise reduction for hearing assistance devices. In various embodiments, a hearing assistance device includes a microphone and a processor configured to receive signals from the microphone. The processor is configured to perform noise reduction which adjusts maximum gain reduction as a function of signal-to-noise ratio (SNR), and which reduces the strength of its maximum gain reduction for intermediate signal-to-noise ratio levels to reduce speech distortion. In various embodiments, the hearing assistance device includes a memory configured to log noise reduction data for user environments. Also provided are methods to further adjust the noise reduction based on the logged information.

摘要： The signal processing functions of a hearing aid as described above necessarily cause some delay between the time the audio signal is received by the microphone or wireless receiver and the time that the audio is actually produced by the output transducer. In some situations, signal processing incorporating longer delays may be better able to improve signal-to-noise ratio (SNR) or other functional parameters for a hearing aid wearer, but a balance should be struck between these positive effects of delay and other negative effects. The techniques described herein address the problem of to balancing the positive and negative effects of delay.
摘要翻译：如上所述的助听器的信号处理功能必须在由麦克风或无线接收器接收音频信号的时间与输出换能器实际产生音频的时间之间产生一些延迟。在某些情况下，包含更长时间延迟的信号处理可以更好地提高助听器佩戴者的信噪比（SNR）或其他功能参数，但应在延迟和其他负面影响的这些积极影响之间取得平衡。本文描述的技术解决了平衡延迟的正面和负面影响的问题。
