### undeaf

* **undeaf**(`params`): `Promise<void>`

Unmutes the incoming audio for a given member. The affected participant will start hearing audio from the other participants again.

Note that in addition to allowing a participants to hear the others, this will also automatically unmute the microphone of the target participant. If you want, you can then manually mute it by calling [audioMute][video-roomsession-5].

#### Parameters

<ParamField path="params" type="object" required>
  Object containing the parameters of the method.
</ParamField>

<Indent>
  <ParamField path="memberId" type="string">
    ID of the member to affect.
  </ParamField>
</Indent>

#### Returns

`Promise<void>`

#### Example

In this example, we mute a member when they join the room, and then unmute them after 5 seconds.
This example assumes that there is a [`RoomSession`][roomsession-41] already active and users are joining it.

```js
import { SignalWire } from "@signalwire/realtime-api";

// Initialize the SignalWire client
const client = await SignalWire({ project: "ProjectID Here", token: "Token Here" });

// Access video client from the main client
const videoClient = client.video;

// Setup listener for when a room starts
await videoClient.listen({

  onRoomStarted: async (roomSession) => {
    console.log("Room started", roomSession.displayName);
    await roomSession.listen({
      // Listen for when a member joins the room
      onMemberJoined: async (member) => {
        console.log("Member joined", member.name);
        // Deafen the member
        console.log("Deafing member", member.name);
        await roomSession.deaf({ memberId: member.id });

        // Undeafen the member after 5 seconds
        setTimeout(async () => {
          console.log("Undeafing member", member.name);
          await roomSession.undeaf({ memberId: member.id });
        }, 5000);
      }
    });
  },
  onRoomEnded: async (roomSession) => {
    console.log("Room ended", roomSession.displayName);
  }
});
```
