Main features


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

To simplify on-site installation, Fusion has a function for the automatic detection of a calibration acoustic source which lets you calibrate and adjust the instrument without doing anything more than switching on the device.

An integrated measurement-chain verification system also performs periodic checks automatically. Electrical verification tests the entire measurement chain, including the microphone by injecting an alternating sinusoidal load on the microphone’s terminals at the selected frequencies, at one or two levels. The principle is to read reference values and check the deviation with respect to other measured values over time.

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
