New web interface

Now available in a new 4.1 version, the Acoem WebMonitoring interface has been reviewed in order to enhance the user experience and productivity:

  • new graphical style for improved legibility
  • dynamic tabs to display or hide information
  • new Acoem heatmap graphics
  • new banner with weather information
  • direct integration of the alarm management
  • annual summary page reviewing key indicators
  • summary reports
  • audio and video recording displaying

In the cloud

Data collected by the monitoring stations is transferred to the 01dB data-hosting center on a periodic basis. It is stored and backed-up in order to maintain its integrity. Raw data is remotely accessible by FTP and can be downloaded for further processing with dBTrait software (provided on demand). All data and the project website itself will remain accessible for up to six months after completion of the project. All hosted information is strictly confidential and cannot be used by Acoem or any associated third party.

Alarm management

Noise and vibration monitoring also relates to risk management (e.g. damage to buildings), requiring a reaction almost in real time. As a consequence, Acoem WebMonitoring includes a sophisticated application-oriented alarm management system: triggers based on all available indicators (noise, vibration, weather conditions, etc.), two levels of alarm (orange and red), an alarm count, combination of alarm between two measurement points, and sending alarms information by e-mail.

With WebMonitoring Version 4.1, users can generate alarms directly on a dedicated web interface. To do so, users can view all the monitored items directly on the “Site” page menu, along with the associated alarms indicated by a bell that changes color (green, orange and red) in real time. The bell also indicates the number of alarms registered since the latest acknowledgment by the user.

Heatmap features

HeatMap provides users with a clear and simple overview of the indicators monitored throughout the operation. For example, it enables users to instantly see whether worksite start-up and shutdown times have been respected. It also identifies the time periods during which regulatory thresholds are exceeded.

Based on the principle of a weekly chart displaying average hourly levels in color for each day within a week, HeatMap offers sophisticated features over and above a conventional chart.


With the 3.0 version, Acoem WebMonitoring has been enhanced with an essential features for creating summary reports directly from the Web interface.

Summary report includes the following information:

  • location of the considered measurement point(s) and associated description
  • heatmap over the period displaying the indicator selected by the user
  • list of alarms during the selected period of time
  • variation of the selected indicators over time
  • table of indicators


It is possible to connect a weather station to a noise monitoring terminal, with the data collected then transmitted simultaneously and in synchronization with the acoustic indicators. Weather data is available in real time or offline in various formats:

  • new banner with weather information displayed on the “site” and “station” pages in real time
  • time history on the “station” page in real time and on the “point” page offline

The following data is available in real time:

  • wind speed
  • wind direction
  • air temperature
  • relative humidity
  • rain intensity
  • atmospheric pressure

The Acoem WebMonitoring offer

The WebMonitoring offer includes the provision of interactive measurement stations (OPER@ or dB4). Acoem provides all the necessary accessories (tripod, extension cables, etc.), along with a 3G SIM card and the corresponding phone subscription (unlimited package). The monitoring station is ready for use and simply needs to be started up: its connection to the Acoem server is automatic.

Acoem WebMonitoring is flexible and upgradeable, offering the possibility for each customer to use their own equipment (and/or to invest in new equipment) by combining it with dedicated services (data storage, customized website, application-oriented alarm management, etc.).
