Appendix A : Handset Feedback/Echo Issues
Echo is the unwanted effect of received audio being fed back into the transmit path (microphone)
so that the far end hears their own voice. The amount of echo can vary from low level
background interference to high level cross talk rendering the conversation inaudible.
Echo can manifest itself for a number of reasons including the use of poor quality audio devices,
excessively high volume levels, participants of the same call being in too close proximity and poor
environmental acoustics.
If you’re experiencing echo, your microphone might be picking up your speaker. Try muting
your microphones one at a time to determine the source of the pickup. Also try lowering the
volume of any loudspeaker as this might be picked up by an open microphone. Also, ask the far
end person to try muting their microphone as they may be the source. Consider replacing your
handset / headphones with an alternative product. Cordless headsets for example, seem to be
less prone to cross talk interference than their corded counterparts.
Whilst it is always best to resolve the underlying cause of any echo, echo cancellation techniques
may be employed to reduce or even hide echo altogether.
Most modern browsers have echo cancellation capabilities, but we’ve found that Chrome can be
less effective than others (such as Firefox) in removing the distortion by default. If you’re using
Chrome, the following steps may prove to be effective in removing echo:
Although Microsoft Edge is based on Chromium, it does not have the following echo
cancellation feature.
1. Type chrome://flags/ into your Chrome browser address bar and press <ENTER>.
2. In the search bar at the top of the page, search for Chrome-wide echo cancellation . (Make
sure the ‘Available’ tab has been selected as can be seen in the example below).
3. Select
Default/Disabled
to reveal the drop-down menu of options, from which you can select
Enabled .
