The performance of an echo canceller is measured in echo return loss enhancement (ERLE), [3] [9] which is the amount of additional signal loss applied by the echo canceller. Most echo cancellers are able to apply 18 to 35 dB ERLE. The total signal loss of the echo (ACOM) is the sum of the ERL and ERLE. [9] [10]
A 3.5 mm microphone blocker with just TS channel is enough to disconnect the internal microphone, but most commercial microphone blockers have TRRS connections which in theory makes them headset blockers that in smartphones also disconnect the internal speaker in media player software because they will try to connect to the headphones, while ...

[ 96 ] In September 2018, Amazon announced the Echo Sub , a subwoofer that connects to other Echo speakers, and the Echo Wall Clock , which can display how much time is remaining on timers set ...
An echo chamber is a hollow enclosure used to produce reverberation, usually for recording purposes. A traditional echo chamber is covered in highly acoustically reflective surfaces. By using directional microphones pointed away from the speakers, echo capture is maximized. Some portions of the room can be moved to vary the room's decay time.
The league could have celebrated that athleticism and skill, but instead it handed a microphone to Hart, who spent the first game of the tournament complaining to the crowd about "big men jacking 3s."
