Sound Innovation’s initial focus was on developing Active Noise Reduction (ANR) technology that generates super hearing protection in high noise environments. Now that we have successfully developed the next generation of ANR technology, we are using our background in control algorithms, digital signal processing, and acoustics to develop a suite of technologies that will enable people to:
- simultaneously protect and enhance their hearing
- have clear two-way communication in noisy environments
- localize, identify, and listen to sounds from a distance
Our technologies in various research and development stages currently include:
Next Generation Active Noise Reduction (ANR)
The product of over ten years of research and development, our ANR technology delivers unparalleled active noise reduction performance. In addition to adding noise cancellation to earplugs and over-the-ear headsets, this flexible technology can be used to create a zone of quiet in enclosed spaces such as construction vehicle cabins. The ACE™ is the first product based around our ANR technology. Learn more about how our ANR technology re-defines the state of the art.
Sniper location through reduced order modeling
Sound Innovations is conducting research on using reduced-order models from High Performance Computation (HPC) acoustic transmission models to identify and localize sniper fire. From this research, we hope to develop algorithms for quick and effective sensor placement and fast identification of location of sniper fire. We will incorporate this technology into a light weight, portable system for police forces, ground troops, and others who need to quickly establish a highly accurate sound localization net.
Acoustic binoculars – remote auditory presence through beamforming
Imagine the ability to focus on a target 100 yards away and be able to listen as if you were five yards away. In partnership with Dartmouth College, we are performing research on the concept of remote auditory presence. Remote auditory presence combines distributed beamforming using remote wireless microphone networks with spatial audition - presentation of remotely sensed stimuli to the human ears - in a manner that allows a human to perceive an auditory environment from a distance and specifically to enhance listening to sources of interest.
