Using Beep Sound in PowerShell

This is a just a cool PowerShell technique. If we can use a Beep is our PowerShell Script it helps us a lot. For example you are doing some work on another ie and poweshell script is running in backgroud and if we provide a powershell beep after every task then we able to know that something is working.
we can use 3 beeps before restart laptop using script.
