Settings -> Notifications -> Enable 'Use system sounds' -> Notification sound set to '
Silent.

Turn off your system sounds via control panel. Only a few steps.

Hello,
Viber mirrors your device's notification settings.
... center:
Setting> Notifications>
Viber> turn "Sounds" off.
Good ...

To turn off the incoming message sounds go to Settings > notifications and disable Use System Sounds. You can also disable Outgoing message sounds from the same screen.
