Medusa
Sensor

How it works

The “Medusa” sensor is a patented system which makes sound visible. Due to its unique shape, it is able to calculate the azimuth and elevation angles of the dominant sound source and to mark on a 360° image where the sound comes from. This sensor makes it possible to pinpoint what causes the most nuisances and to tackle noise issues right at their sources.

Our choice was to get as close as possible to the human hearing (which naturally focuses on the dominant noise source).

Acoustic calculations

• LAeq , LCeq every 100ms
• Dominant noise direction : azimut angle and elevation angle, indicator of reliability

The medusa can, at all times, identify with great precision the provenance of the dominant noise.

Imagery

• 360° Photo every 15 minutes
• Automatic face and license plate number blurring on the server
• No audio recording

A great number of medusa sensors have already been deployed on both public and private noise management projects
