Sound with excel
 

I can make the Excel to create 3 different sounds one right after another by
using the following procedure (by Jim Thomlinson):

Private Declare Function Beep Lib "kernel32" (ByVal dwFreq As Long, _
ByVal dwDuration As Long) As Long

Sub BeepTest()
Beep 500, 200
Beep 1000, 200
Beep 2000, 200
End Sub


However, I cannot make all 3 of them sound at the same time.
Can excel do this?
Thanks,
Bau
