Name of notification or name of sound that plays when a website load

I have code that is written to disable a notification sound after a website loads.
The issue is I do not know what the Name of that Notification Sound is.
I have tried just Notification by setting it to "nothing" with the control panel NO Luck.
Here is the code FWIW it is hard to write code if you do not know the names of the Ctr you want to apply changes to. So here is my best guess code.

Module Module1
Sub Main()
    Dim webPAGE As String = "http://www.example.com"
    OpenWebPage(webPAGE)
End Sub

Sub OpenWebPage(ByVal url As String)
    Try
        Dim startInfo As New ProcessStartInfo("chrome.exe", url)
        startInfo.UseShellExecute = True
        Process.Start(startInfo)
    Catch ex As Exception
        Console.WriteLine("An error occurred: " & ex.Message)
    End Try
End Sub

End Module
