Precision acoustic detection

Squarehead is a deep-tech company developing advanced acoustic sensor systems that turn sound into actionable situational awareness. Its proprietary microphone array technology replicates and expands human auditory capabilities—enabling precise detection, localization, and classification of sound events in challenging environments. The company’s solutions serve both defense and industrial markets, providing passive threat detection, drone detection, condition monitoring, and quality control across critical infrastructure and operational settings.

Squarehead’s flagship systems, powered by sophisticated beamforming and machine learning, offer high-resolution acoustic imaging that filters noise and pinpoints anomalous audio signatures such as drones or equipment faults. These passive sensors fill key gaps in traditional detection stacks, enhancing perimeter security, enabling autonomous operations and preventive maintenance without requiring active emissions or complex setups.

Founded in 2004 and headquartered in Oslo with global reach, Squarehead is positioned at the intersection of spatial audio innovation and real-world safety and security needs.
