The affected participant will start hearing audio from the other participants again. You can use this method to undeaf either yourself or another participant in the room. Note that in addition to allowing a participants to hear the others, this will also automatically unmute the microphone of the target participant (even if there is no `audio_unmute` permission). If you want, you can then manually mute it by calling [audioMute](/docs/browser-sdk/v3/js/reference/video/room-session/audio-mute). #### Parameters **`params`** `object` Object containing the parameters of the method. --- **`memberId`** `string` Id of the member to affect. If omitted, affects the default device in the local client. --- #### Returns `Promise` #### Permissions * `room.self.deaf`: to make yourself deaf. * `room.member.deaf`: to make deaf a remote member. You need to specify the permissions when [creating the Video Room Token](/docs/apis/rest/video/room-tokens/create-room-token) on the server side. #### Examples Undeaf yourself: ```javascript await roomSession.undeaf(); ``` Undeaf another participant: ```javascript const id = "de550c0c-3fac-4efd-b06f-b5b8614b8966"; // you can get this from getMembers() await roomSession.undeaf({ memberId: id }); ``` > undeaf method for the RoomSession class.
