In recent Plasma 5, search "Audio Volume" in the application launcher and, under 'Applications' tab, disable 'Notification Sounds'.
In some Plasma versions the above doesn't work, as I now see in Kubuntu 17.10. The Audio Volume tool looks different and notifications sounds is already muted.
To stop the volume scrolling sound etc in this case, I have unmuted, and moved the slider to zero, and muted again. Something is buggy here though, as the slider is in fact always stuck to zero, and only the mute/unmute button does the work.
In this case I have noticed that a different tool can be used: pavucontrol-qt:
After using this, the bug mentioned (slider stuck to zero in "Audio Volume") disappeared.
Open System Settings and click on Notifications:
In the Notifications window, first select the event source for which you want to configure notification, in this example, I chose Plasma Workspace. In the table, the first column reflects the state of an event. When a sound has been configured, a little play button is displayed. If you want to disable the sound for a certain event, click on the event and deselect the Play a sound checkbox. You can quickly disable all sounds for a certain event source by clicking the button Disable sounds for all of these events.
If you want to disable all notification sounds, you have to select each event source and click the "disable all" button. AFAIK, it's not possible to disable all sounds with one click.
However, it is possible to mute them. If you go again in System Settings -> Multimedia -> Audio Volume, you can simply mute all notification sounds:

In KDE 4.10.5, you can disable all system sounds without muting all media.
System Settings>Common Appearance and Behaviour>Application and System Notifications>Manage Notifications>Player Settings>No audio output.Also, you may disable Event Sounds: left click the sound tray icon and slide down the Event Sounds slider or completely mute it.
In KDE Plasma 5, you can left-click the kmix (volume) plasmoid, and turn down "Event Sounds", similarly to the screenshot above.
If this doesn't work, you can turn off the sounds for each notification class individually, in
System Settings>Notifications. Cycle throughEvent source, looking for entries with thePlay a soundicon associated with the entry, then toggle offPlay a sound.
