Technology : Adaptive Noise Reduction

Welcome to our virtual office of Technology Research in San Jose, California, USA.

You may have heard that “Pictures are worth thousand words, but only the sounds tell a story.”

Unfortunately, all things, both inanimate and animate objects, try to tell us its own story and competes for our ear. These fierce fight for our attention wares us down during our busy lives.

Consequently, we have developed an adaptive audio processing algorithms to selectively enhance the sounds of our interests while suppressing the sounds of our disinterests.

Our algorithm heuristically learns the familiar voices of friends and families to pick them out from extremely noisy environments to help us listen better.

When applied to occupational safety earmuffs, it can minimize the harmful noise while allowing us to normally carryout usual conversations with our coworkers while being fully aware of acoustical sounds that needs to be monitored.

Listed below are some of its features and many possible applications. Please let us know if you are interested in licensing these technologies.
