How to explore the unified coverage map

HDL410 system with Nureva® Console cloud
Last Updated: March 20th, 2023

What is the unified coverage map?

When an HDL410 system calibrates it determines the location and orientation of each microphone and speaker bar that is in a room. A coverage map is generated that represents the area between the microphone and speaker bars. The coverage map demonstrates a field of virtual microphones and where sound is being picked up in the room. Sound location data is collected continuously and is not dependent on an audio or video conference for collection.

As the HDL410 system captures sound location data the coverage map updates to show any changes in the data. The updates occur every minute and present the last five minutes of sound location data. 

Example

  • 12:00 pm - Nureva Console cloud is first viewed showing data from 11:55 am to 12:00 pm
  • 12:01 pm - The coverage map is updated showing data from 11:56 am to 12:01 pm
  • 12:02 pm - The coverage map is updated showing data from 11:57 am to 12:02 pm
  • Updates continue every minute while the coverage map is viewed

The maximum area represented by the coverage map is 35' x 55' (10.7 x 16.8 m) which is the default area. To better represent the actual room size the coverage map area can be changed. Adjusting the coverage area to the actual room dimensions helps refine the sound location data and provides a more accurate coverage map. This is useful in helping ensure that sound picked up from outside of the room is not included in the data used to create the coverage map. 

Viewing the coverage map

To view the coverage map the HDL410 system must be powered up and enrolled into Nureva Console cloud. 

  1. Launch Nureva Console in a browser and sign into your account
  2. From the Rooms dashboard choose a room with an HDL410 system

The dashboard for the selected room displays a view of the coverage map. This provides a quick glance at the system setup and sound location data that has been captured in the past 5 minutes. Select the Coverage map button on the navigation side menu or click the Edit room size button to view the detailed coverage map.

After the coverage map opens the sound location data collected over the past 5 minutes is displayed on the map. When an HDL410 system is set up for the first time sound location data may not be available. Walking around the room perimeter and speaking will provide a source for sound location data to be collected and displayed.

Editing the room size

The blue circles on the coverage map indicate where sound location data is being generated within the room. Two options are available for adjusting the room dimensions.

  1. Move the drag handles on the coverage map to the correct room dimensions
  2. Use the room dimension fields on the right-hand side of the dashboard

As the room dimensions are adjusted the coverage map and room dimensions will update to the corresponding input.  The more sound location data that is created in the room the easier it is to adjust the room size accurately.

When the room dimension adjustments are complete press the Apply button.

Once the edits have been applied the coverage map will return to a zoomed-in view and exclude any sound location data outside of the updated dimensions. The room dimensions can be edited again at any time by pressing the Edit room size button.

Clearing the sound data

The displayed sound data updates every minute and presents the last five minutes of sound location data. To reset the coverage map and populate new data press the clear sound data button. After pressing the button the coverage map will clear the data and new data will start to populate. The data populates every minute.

Ensure accurate room data

Nureva audio conferencing systems have two types of calibration – automatic calibration and recalibration. Automatic calibration is a continuous process and occurs while the system is powered. Recalibration is a process that helps ensure optimum sound quality and accurate sound location data after a change in a system or room configuration.

If the HDL410 system was powered up for the first time in a different location a recalibration should be completed once installed in the room.

Nureva Console

  • Navigate to the device settings Console client or cloud
  • Choose Audio processing
  • Scroll to Recalibrate and click on Start
  • The calibration will be complete when the calibration sound stops

Remote control

  • Press the F4 button on the remote five times in quick succession
    • A single blue LED will start flashing on the microphone and speaker bar
  • Press the Mute button on the remote
    • The system will enter the recalibration sequence and the LED will alternate between solid red and blue lights
  • The calibration will be complete when the calibration sound stops
