Triton Systems is developing novel sonar and hearing protection solutions for Department of Defense and commercial applications. Technologies include acoustic metamaterials, noise isolation for improved communications in loud environments, high performance sonobuoy design, hearing protection with enhanced situational awareness, acoustic signal processing, MEMs technology, and ruggedized acoustic systems. These technologies are tested using Triton’s acoustic facility, including an Eckel anechoic chamber, high sensitivity microphones, and real time multi-channel recording and analysis capability.
Engineered acoustic elements creating an acoustic metamaterial
Our Accoustics group worked to model, assess and develop counter-measures to the potential threat of acoustic cloaking to avoid sonar detection by the Navy. We studied the Navy need to both address the potential benefits and threats that successful acoustic cloaking technology would provide, estimating whether acoustic cloaking technology would be feasible within a 5 to 10 year time frame, and to develop suitable countermeasures for the defeat of cloaked objects.
Diver Hearing Protection Helmet
Noise attenuation and pressure equalization
Navy divers experience high noise levels during typical operations from tools and air supply. They cannot wear traditional hearing protection devices due to dive conditions. Responding to this critical need, Triton developed an innovative approach to noise attenuation and improved communication in dive helmets.
Noise Dose Monitoring
Ability to monitor noise levels with any earplug
VA compensation for hearing loss is currently at $2B annually, and it is the top disability facing soldiers as they return home. With our expertise in acoustics, sensors, and Microsystems, we are currently developing an in-ear noise dose monitoring system to qualify and evaluate earplugs and other hearing protection as worn by the specific end-user, and monitor actual noise exposure.
Non-Linear Hearing Protection
Non-linear attenuation, blocking loud sounds while allowing quieter sounds to pass
During normal operations the Warfighter is exposed to dangerous noise levels, but many do not wear available hearing protection devices because they impede their situational awareness and ability to communicate. Our innovative passive earplug activates noise attenuation in the presence of loud sounds but allows sound to pass through in normal noise environments.
Enhanced sonar algorithms using existing sonobuoy structures
Sonobuoys are a key tactical tool for gathering intelligence and creating controlled areas. Triton has developed a variety of innovative technology approaches for emerging sonobuoys. The team is currently developing improvements to the AN/SSQ-101B with improved processing algorithms to increase detection capabilities.
Structural Noise Reduction
Innovative, simple, and low-cost improvements to the sonobuoy structure to significantly reduce noise
Sonobuoys are a key tactical tool for gathering intelligence and creating controlled areas. Triton has developed a variety of innovative technology approaches for emerging sonobuoys. The team is currently developing improvements to the AN/SSQ-101B structure to reduce structure-borne noise contamination, ultimately increasing detection capabilities.
