Noise visualisation “Meduse” sensor
The Méduse sensor works like an acoustic camera. It provides continuous visual identification of sources and levels of surrounding noise.
Its visual identification system takes 360° photographs every 15 minutes, with an accuracy of locating the dominant acoustic source to within 1° of error in 70% of cases.
As pre-approved technology by the Hong Kong Construction Innovation Technology Fund, you can benefit from a subsidy when purchasing the sensor for your project.

FAQ
How must the sensor be mounted?
Microphones must be pointing downward.
Does the sensor comply with data protection legislation?
The sensor, its software and recognition algorithm comply with the European GDPR regulation.
Are specific authorisations necessary to set up the sensor?
Authorisations must be granted in order to mount the sensor on public property or historical monuments. UBY does not apply for these authorisations on behalf of the client.
No specific authorisations are necessary when being installed on private property.
