Nureva Received Fourth Patent for Microphone Mist Technology

nureva patentNureva just announced that the U.S. Patent and Trademark Office has issued patent number 10,499,151 for embedding additional information in a sound mask noise signal. This is the company’s fourth patent for its Microphone Mist technology platform, which powers its HDL300 audio conferencing systems and the HDL200 system that was announced earlier this week. The patent describes the ability of the microphone and speaker system to create a continuous sound mask signal that enables an impulse response measurement for each microphone and speaker combination in real-time. This allows the system to instantly autocalibrate the multichannel echo canceler for each speaker to microphone combination and provide continuous, real-time, in-room impulse response measurements. Unlike competing products, Nureva says its audio systems maintain consistent performance by automatically and continuously adapting to changes in room configurations or a change in the location of the Nureva system itself. For example, no manual recalibration is required by IT staff or a service technician when furniture or mobile walls are moved to accommodate varying meeting scenarios.
