Why explore signal-to-noise ratio data?

Exploring signal-to-noise ratio levels can give insights into:

• Compare signal-to-noise ratio across multiple rooms
• Troubleshoot when audio issues are reported
• Proactively detect and correct issues
• Identify where to invest in improving room acoustics

NOTE: This data is only available from HDL300, Dual HDL300, HDL310 and HDL410 systems.

What signal-to-noise ratio data is available?

The signal-to-noise ratio chart shows the average signal to noise levels over time for the selected room, measured in decibels (dB). It also shows the minimum signal-to-noise ratio level recommended by Nureva for comparison.

Nureva advises a minimum signal-to-noise ratio of around 15 dB. If Analytics is consistently reporting a signal-to-noise ratio below 15 dB when people are speaking in the room, we recommend investigating what can be done to increase the signal-to-noise ratio.

To help you remember that values above 15 dB are desired, the area above the recommended line is shaded grey with the word ‘BETTER’ displayed in white letters. This is in contrast to the background noise chart, where values below the recommended line are desired.

Investigating signal-to-noise ratio levels can help to troubleshoot audio issues. If background noise levels in a room are higher than recommended levels, the signal-to-noise ratio advises whether the background noise is interfering with audio quality for remote participants.

Conversely, if the signal-to-noise ratio levels are consistently low when people are speaking in the room, checking the background noise levels in the room can help you determine whether the low signal-to-noise ratio indicates an issue with background noise or with the voice levels.

If background noise levels are within the recommended range and signal-to-noise ratio levels are low, it could potentially point to people talking too quietly. If that is not the case, try repositioning your Nureva audio device so that it is closer to where people are located. This will be especially impactful if using the audio device in a room that is larger than recommended by Nureva.

How to explore signal-to-noise ratio 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 signal-to-noise ratio data
  • With a Nureva Pro plan: If a custom date range is entered, this selection will persist when exploring the chart

Explore signal-to-noise ratio 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 sound location 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 - 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
   • The example above has a timeframe from 7:00 am to 7:00 pm
     • Data captured on the selected days between 7:00 am and 7:00 pm 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

3. Select a room
   • Use the radio buttons to view and compare data for different rooms
4. Chart interactions
   • Hover over a particular data point to see a popup that shows the time stamp and the data value for that x-value
   • Use a mouse or trackpad to zoom into the chart to view data on a smaller time scale

Exporting signal-to-noise ratio data

Signal-to-noise ratio data can be exported as a .csv file. 

• Click the export icon in the top right corner of the signal-to-noise ratio chart
  • 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
  • The export button will be disabled if there is no data visible in the chart
