Sound event detector
SED (Sound Event Detector) is a solution that uses a proprietary algorithm driven by machine learning technology to detect, classify and subsequently alert on unwanted acoustic events. These events can be a gunshot, a scream, or high urban noise levels.
The SED has exceptional accuracy that provides the confidence to address threats quickly and avoid wasting resources on false alarms. In addition, this solution enables sound detection to operate on devices with low-power, low-cost processors.
Step 0: Adaptation
The SED analyzes the common background sounds from the environment in which it is located and adapts.
Step 1: Detection
The SED detects an unwanted sound event that is atypical in the environment.
Step 2: Extraction
The SED processes the input audio signal and extracts the audio features used to train the classifier.
Step 3: Classification
The SED triggers an alarm if the event is evaluated as undesirable.
Step 4: Result
The SED triggers an alarm if the event is evaluated as undesirable.
Step 5: Notification
The SED informs the user about the event, and help can be on the way immediately.
Software solution of Sound event detector
Sound event detector’s SW solution is powered by state-of-the-art machine learning techniques with optimized deep neural network architectures running on low-power MCUs in real-time.
The software has been developed with an emphasis on speed and efficiency and allows third parties to easily adapt it to their embedded (low power) hardware platforms. The solution comes with a very intuitive user application, and both products can be customized to suit your needs.
It’s not a problem if you don’t want integration into your product; we also have our own devices ready for immediate order!
Hardware solution of Sound event detector
The Sound Event Detector (SED) alerts to specific sound events and monitors environmental noise. The SED detector uses an AI algorithm to detect, classify and alert on dangerous or critical sound events. It is not a noise sensor.
The SED detector will alert on sound events such as glass breaking, gunfire, panic screams, aggression, graffiti spray, grinder, drill and drone. It can also monitor noise levels.
The SED detector can be purchased for both indoor and outdoor detection of sound events. It can also be used as software for security cameras. A new feature is the SED with built-in camera.
