ActiveVent speaker/receiver Phonak

The ActiveVent speaker is an innovative speaker technology that contains a mechanically switching ventilation opening. With the speaker your voice sounds natural again and you can hear optimally again.
The speaker is controlled by AutoSense OS™ 4.0, which automatically adapts your hearing aids to the environment and is compatible with all Audéo Paradise rechargeable hearing aids.
ActiveVent attaches to your Audéo Paradise rechargeable hearing aids. The speaker then blocks noise in noisy places for optimal hearing in these difficult situations. You will also maintain a comfortable and natural listening experience in quiet environments.
Opened position:
When the disc is in the open position, direct sound can pass through the receiver's built-in venting system, allowing the wearer to experience the comfort of an open fit, with the natural sounds of their own voice, and to pick up ambient sounds.
Closed position:
In challenging listening situations with speech in noise or when streaming, the disc switches to a closed position so that ambient noise does not enter the ear directly. This makes speech from the front and streamed audio easier to understand.
This is all controlled intelligently and automatically by AutoSense OS 4.0. Thanks to a clicking sound, the client knows that the disk has changed positions.
