PersonApp requests echo cancellation and noise suppression, but room setup still matters. The best fix is using headphones and reducing speaker leakage near your microphone.

## Steps

1. Use wired or Bluetooth headphones to prevent speaker audio looping back into mic.
2. Lower speaker volume and keep microphone away from output sources.
3. Enable OS noise reduction options if available on your device.
4. Rejoin call and verify audio clarity with a new partner session.

## Frequently Asked Questions

### Why does echo happen only with some partners?

Echo can originate from either side depending on device acoustics and speaker volume.

### Can browser extensions add audio noise?

Yes. Audio-processing extensions can distort capture and should be disabled for testing.
