Abstract: A hearing device includes: a first input transducer configured to convert an acoustic signal into a first input signal; a processing unit configured to provide a processed signal based on the first input signal; an acoustic output transducer configured to provide an audio output signal of based on the processed signal; a second input transducer configured to provide a second input signal based at least on the audio output signal from the acoustic output transducer and a body-conducted voice signal from a user of the hearing device; and a user voice extraction unit connected to the processing unit for receiving the processed signal, and connected to the second input transducer for receiving the second input signal, wherein the user voice extraction unit is configured to extract a voice signal based at least on the second input signal and the processed signal.

Abstract: A system and method for detecting a non-visual code using an application on a mobile device, where the application is capable of associating the non-visual code with at least one item contained in a transmitted presentation and connecting the mobile device to information about the item in a database associated with the transmitted presentation. The non-visual code may comprise a high frequency signal played alone or with another audio or video signal. A mobile device application executing on a processor of the mobile device performs signal processing on the audio signal of the presentation to extract the high frequency signal. Also contemplated is obtaining information about the visual content and presenting the information on the personal device.
