Why explore sound location data?

Exploring sound location data can give insights into:

• How meeting rooms are being used
• Whether meeting rooms are being used effectively, from a space perspective

NOTE: This data is only available from HDL410 systems.

What sound location data is available?

The sound location visualizer provides data about the loudest sound detected in the room during the selected period. This is measured several times per minute.

NOTE: The sound coming from the HDL410 speakers is not included in the data.

The sound location visualizer uses a bird’s eye view to show where the loudest sound in the room originated from during the timeframe. The data points are shown relative to both the microphone and speaker bars. 'Port 1' indicates the bar connected to the RJ45-1 port on the connect module. 'Port 2' indicates the bar connected to the RJ45-2 port on the connect module. The room dimensions are taken from the coverage map settings.

The sound location data is processed presuming that sounds that are in close proximity to each other originated from the same location. When sounds are detected in the same part of the room on multiple occasions, the data points will overlap and appear darker in color. Therefore, the darker the color, the higher the concentration of the loudest sounds that are detected in that part of the room.

Explore sound location data in the room at different dates and times to determine if there is a pattern to the location of the sounds. Identifying patterns of use can help you understand whether your rooms and Nureva audio devices are being used effectively.

How to explore sound location data

• Access the Analytics feature by logging into Nureva Console cloud and navigating to Analytics in the left-hand navigation menu

• On the Analytics landing page are the Device usage, Background noise, Sound location, and Signal-to-noise ratio charts
  • The charts show data for the first room in your organization alphabetically
  • View and compare data for different rooms using the 'Select a room' dropdown menu

• With a Nureva Pro plan
  • By default, these charts display data from the past week
  • Change the date range using the Date range selector found on the top right-hand side of the browser window
  • Select a single day or a date range of up to 31 days
• With a standard plan
  • Try out this Pro feature by viewing data from the past 3 days, but the date range cannot be changed

• From the landing page, click the Explore button for sound location data
  • With a Nureva Pro plan if a custom date range is entered, this selection will persist when exploring the chart

• See a larger version of the sound location visualizer from the landing page

Explore sound location data via the following controls:

• Any changes that are made to these options will persist when you navigate to the device usage, background noise, or signal to noise ratio charts

1. Date range
   • With a Nureva Pro plan
     • Change the date range by clicking on the calendar icon   
     • Select a single day or a range of up to 31 days
     • The example above has a date range of June 14 to June 21, 2023
   • With a standard plan
     • Try out this Pro feature by viewing data from the past 3 days, but the date range cannot be changed
2. Timeframe
   • This setting filters the data from the selected date range to show only certain times from each day
   • For example, the image above has a date range of Oct 19 - Oct 26, 2022, and a timeframe from 7:00 am to 7:00 pm
     • Data captured between 7:00 am and 7:00 pm on each of those days is displayed
   • Change the timeframe using the dropdown menus for Start time and End time
     • The minimum range is 1 hour
   • The time zone is taken from the system time of the computer being used to access Analytics
     • This may not be the same as the time zone where the Nureva audio device is located

Selecting a larger time frame will result in a visualization that focuses on the ‘big picture’. Data points that do not contribute to a larger pattern of use are removed to make it easier to spot such patterns. To see more detailed sound location data, try selecting a smaller timeframe.

3. Select a room
   • Use the radio buttons to view and compare data for different rooms

Filtering sound location data

The sound location visualizer provides filtering controls to help identify patterns in the data. Filtering options allow for the reduction of ‘noise’ in the data in order to increase the observability of trends. You can filter the sound location data in 2 ways:

1. Filter by sound level
   • For example, filter out all sounds below a decibel (dB) level
   • Sounds that are below 45 dB are not included in the data
2. Filter by sound duration
   • For example, filter out sounds lasting less than 4 seconds
   • Sounds that last less than 0.5 seconds are not included in the data

Any changes made to the filters will not persist when you navigate away from the page. 

Using the filtering tools

• Click the filtering icon in the top, right corner of the sound location visualizer

• Adjust the sound level slider (top slider) to filter by sound level
  • The range is 45 dB to 75 dB

• Adjust the sound duration slider (bottom slider) to filter by sound duration
  • The range is from 0.5 second to 15 seconds 

Exporting sound location data

Sound location data can be exported as a .csv file. 

• Click the export icon in the top right corner of the sound location visualizer
  • The data currently visible in the chart will be downloaded via the browser
  • The .csv file will reflect the date range and time filter selected at the time of export, as well as the current sound level and sound duration filter selections
  • The export button will be disabled if there is no data visible in the chart

Troubleshooting

Sound location data is only available for rooms with HDL410 devices. In order to view this data, the HDL410 device must be fully connected. If one or both microphone and speaker bars are disconnected from the connect module, you will not be able to see the sound location data chart. Instead, you will see a message that says, 

“Sound location data is only available for rooms with HDL410 devices.”

Furthermore, sound location data can only be collected when both microphone and speaker bars are connected to the connect module. If one or both microphone and speaker bars were disconnected from the connect module you will see a data gap in the sound location chart.
