摘要： The sound quality of a hearing aid device with a directional microphone system is to be improved. For this purpose, the microphone signals of microphone units with directivities of different orders are analyzed and divided into frequency bands. A weighting of the microphone signals that are emitted from the microphone units with directivities of different orders takes place in the individual frequency bands. The weighting takes place in particular in dependence on the signal level of the microphone signals.

摘要： A system and process for sound source localization (SSL) utilizing beamsteering is presented. The present invention provides for improved beamsteering with less drain on system resources while providing accurate, real time results. To accomplish this, the present SSL system and process rejects as much as possible extraneous audio frames and analyzes only those frames exhibiting a well defined sound source. In addition, the number of beams is reduced as much as possible to save on processing time, but a full scan of the working volume is still made with the beams. And finally, interpolation is used to increase the precision of the technique.

摘要： A system and method for playing audio material is described. The audio material is illustratively downloaded from a network, or from a storage media, each coupled to a loudspeaker through a speaker drive unit. A speaker authorization signal is provided to the speaker drive unit from the network or storage media. The speaker drive unit provides an audio signal to the loudspeaker if the authorization signal indicates that the loudspeaker is authorized to play the audio material. The speaker drive unit does not provide an audio signal to the loudspeaker if the authorization signal indicates that the loudspeaker is not authorized to play the audio material. The system and method includes a monitoring unit to furnish a signal indicating the sound generated by the loudspeaker, to be stored, and to determine whether the loudspeaker has played the audio material.

摘要： Audio is adaptively associated with speakers, depending on the speaker configuration that is present. Each speaker it receives an audio assignment based on its individual spectral characteristics. As more speakers are added, content is adaptively associated with that you speaker, and taken away from the previous.

摘要： In accordance with the teachings described herein, systems and methods are provided for a hearing instrument with self-diagnostics. A detection circuitry may be used to monitor the functional status of at least one transducer by measuring an energy level output of the transducer and comparing the energy level output to a pre-determined threshold level. The detection circuitry may generate an error message output if the measured energy level output of the transducer falls below the pre-determined threshold level. A memory device may be used to store the error message output generated by the detection circuitry.

摘要： When the speaker is registered or verified, the supplying part outputs an interference sound signal to cause the loudspeaker to emit interference sound. In the sound inputted to the microphone, the canceling part cancels the component corresponding to the interference sound fed back to the microphone. Using the sound in which the component corresponding to the interference sound has been canceled, the collating part registers or verifies the speaker.

摘要： A control circuit for an amusement device includes a sound detector, a band-pass filter, a peak integrator and a controller. The sound detector is configured to detect audible sound signals. The band-pass filter is electrically coupled to the sound detector. The band-pass filter is configured to extract sound signals in a predetermined audible frequency range and to output a corresponding filtered signal. The peak integrator is electrically coupled to the band-pass filter. The peak integrator is configured to receive the filtered signal, to average peaks of the filtered signal and to output a trigger signal based on a predetermined range of the averaged filter signal. The controller is electrically coupled to the peak integrator. The controller is configured to receive the trigger signal and to provide a control output in response to the trigger signal.
