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

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

Viber mirrors your device's notification settings.
iPhone users:
Turning incoming message sounds off ... done on iPhone via notification 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.
