Acoustic Fingerprinting Used to Detect Glass Break, Gunshot and Other Acoustic Events in Advance of Traditional Emergency Services Notification

November 6, 2013 – Arcturus Networks Inc. demonstrated today at Designing with Freescale Toronto, a software subsystem with a library of acoustic profiles for the creation of intelligent audio sensor devices. The solution is intended for remote home monitoring, security and public safety applications in which an early warning system may improve responsiveness or provide valuable information during an emergency situation. The system is capable of listening and identifying a number of unique audio events, such as:

  • Gun-shot
  • Glass-break
  • Scream detect
  • Domestic smoke alarm
  • Domestic carbon monoxide alarm
  • T3 Evacuation Signal (ISO / ANSI /NFPA)
  • Dog bark
  • Baby cry
  • Electronic personal safety alarm
  • Assault whistle
  • Hand clap
  • Undeclared audio event

The subsystem can operate in a connected or standalone mode. It samples ambient audio to look for a trigger event, typically a change in the audio level. The trigger causes the device to begin an analysis of the audio or transmit the audio data to a remote processing server. The temporal, frequency, pattern, amplitude and other characteristics are used to create an acoustic fingerprint which is then compared with existing profiles to determine a match. The M2M hosted nature of the connected mode, enables service providers to tweak detection profiles, minimize false positives, increase accuracy and extend the practical application of the system. The solution is intended to coexist with full duplex audio applications such a two-way voice communication, engaging and disengaging as required. The system provides a unique differentiator for service providers looking to maximize the value of an in-unit two-way voice communication system and remote monitoring infrastructure.

“The combination of an audio sensor with our M2M and VoIP middleware, means that security monitoring applications have an early warning system that gives them explicit information about the profile of an emergency situation, before emergency services are even notified,” said David Steele, product manager, Arcturus. “Being able to provide this information, in advance, may significantly improve the preparedness of a response and the overall safety of all involved.”

Pricing and Availability

The demonstration is part of an on-going middleware development in collaboration with industry partners and select Arcturus customers. General availability is scheduled in Q2 2014 and will be distributed as an optional package in the award-winning suite of Arcturus middleware.
