HACARUS Inspect for Noise InspectionHACARUS Inspect for Noise Inspection

Detecting abnormalities with smarter analysis - suitable for all environments.

Noise inspection is used in various situations, such as industrial sites for machinery inspections, bridges and tunnels for infrastructure defect detection, and factories for product inspections.
Due to a lack of technicians with a “trained ear”, and an abundance of inspection sites, noise inspection is currently an under-used approach.
Based in Sparse Modeling AI, HACARUS’ noise inspection services can be applied in various environments with ease - and with less training data.
Our model’s lightweight design allows for greater flexibility, enabling integration into existing hardware without the need for an external network connection.
We provide constant inspection capabilities for factories as well applications for bridge and tunnel monitoring using sound collection microphones.

  • Ease of integration in existing
    systems with lightweight AI

  • Accurate results,
    regardless of the environment

  • Monitoring capabilities without
    network connection
