You cannot change or disable the usual Internet Explorer sound cues that become associated with your application, when hosting the WebBrowser Control in an application, without changing the ones for Internet Explorer itself.

The documentation states you can use the sounds tool in the Control Panel or certain registry keys to disable or change the sounds for any application. However, since the WebBrowser Control inherits the standard Internet Explorer, these methods do not work for any applications hosting the WebBrowser control.

The only way to turn off or change the sounds in your application is to turn them off or change them for Internet Explorer.

To disable or change the sounds for any application, you can use the sounds tool in the Control Panel. That is not a viable option when your goal is a simple uniform mass installation. In this case, you can modify the appropriate registry settings for your application.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Each sound for a navigation event has its own registry entry. You can either change the name of the sound file played, or remove the filename to stop any sound being played for that event.

The keys are named in the following way

[HKEY_CURRENT_USER\AppEvents\Schemes\Apps\APPNAME\SOUNDNAME\.Current]
				

For example, [HKEY_CURRENT_USER\AppEvents\Schemes\Apps\Explorer\Navigating\.Current] @="" would remove the sound cue for the Navigating event of Internet Explorer and your Web browser application.

This behavior is by design.
