Linear Sources with Non-Linear Distribution of Soung Energy
Original language description
The present contribution introduces a method of calculation of linear sources with non-linear distribution of radiation of sound energy. In practical circumstances we often meet sources the structures of which approach those of current HVAC ducts but with dimensions and mode of radiation completely different. Concerned are light stacks of factories, refuse incinerating plants, etc. The core of the problem is that a stack must be considered as a linear source where sound power is radiated in two parts. The first at the top of the stack (point source) and the second, considerably greater, by the outer surface of the stack (linear source). Sound power, however, is radiated by the outer surface of the stack in a non-linear mode and drops from the flue gasinlet to the top of the stack. In projects it is therefore very difficult to predict how must a stack radiate sound energy in order to prevent exceeding hygienically permissible limits.
