Understanding AEC

Overview 

Acoustic echo happens when sound from the speakers reaches the microphone and loops back into the call. Pleneo's HearClear™ AEC Gen 2 removes that echo automatically, before anyone notices. Only your voice is sent to the call.

What it does for you

In any room, sound from the speakers reflects off walls and surfaces before reaching the microphone, and those reflections create echo. HearClear AEC Gen 2 removes that echo in real time, so the far end hears only the people in the room, never themselves.

• Remote participants don't hear their own voices come back

• Speech stays clear, never clipped or artificial

• No feedback, no distraction

• It runs continuously in the background, with nothing to manage

Adapts in real time 

Rooms change. People move. Conversations overlap. HearClear AEC Gen 2 keeps up automatically:

• Handles people speaking at the same time

• Adapts as people move or volume changes

• Stays effective as room conditions shift

The result is clear speech, without cut words or an artificial sound.

Why it matters

With HearClear™ AEC Gen 2 working properly:

• Remote participants don't hear themselves

• Conversations feel natural and uninterrupted

• There's no feedback or distraction

You don't need to manage it. It runs continuously in the background

Why it matters 

Without echo cancellation, calls become tiring and confusing. Echo slows conversation, breaks focus, and can get bad enough to end a call early.

With HearClear AEC Gen 2:

• Voices are clean and consistent

• Everyone hears only what's intended

• Conversations flow naturally

In summary 

HearClear™ AEC Gen 2 is Pleneo's acoustic echo cancellation. It removes speaker echo before it reaches the call.

• Prevents voices looping back

• Adapts automatically as the room changes

• Keeps speech natural and clear

If calls sound clean and echo-free, HearClear AEC Gen 2 is doing its job.
