- Model OPER@ - Noise Measurement and Monitoring Station


OPER@ is a class-1 noise measurement station (LNE-approved since 2007) with outstanding technical features: 2 measurement channels, advanced management of events, unique acoustic indicators (dose, sliding Leq, etc.), management of actions on events (MP3 audio recording, alarm, etc.), remote real-time listening, etc.

The OPER@ station, which is connected to the network through a 3G or ADSL modem, automatically and periodically sends measured data to a central server. The user can then directly process the data stored in a database using the OPER@ suite and the dBTRAIT processing software.   

The users can also opt to use the 01dB WebMonitoring, a Cloud solution, in order to free themselves from all technical network set-up requirements. In this case, they can view their data on a public or private Web site suited to their monitoring.

OPER@ has been designed to address all noise monitoring applications, such as:

  • Noise and Vibration Management of Building Sites,
  • Noise Management of Cities (European Directive 2002/49/EC),
  • Noise Monitoring of Airports,
  • Noise Monitoring of Recreational Activities...

OPER@ offers all its power to help the user to manage noise in monitoring projects and to make decisions quickly.
