===========================

CalcDecibelService gives access to the DECIBEL module.
It only contains two function, ``CalcDecibelService.GetDecibelCalc(Handle)`` for getting a shadow objects and
``CalcDecibelService.SetDecibelCalc(shadow_obj)`` for passing it back to windPRO.
The decibel calculation object can be modified and passed back to windPRO.
