Open-to-Ducted Transfer Function for Point Dipole Sources
Open-to-Ducted Transfer Function for Point Dipole Sources
his paper concerns the acoustic radiation from open and ducted sources. Many rotors and fans utilise ducts to improve air flow and quality. In this paper, we relate the radiation of ducted and open sources to form an open-to-ducted transfer function, capable of predicting the effect of shrouding an open source in a duct. A key part of the investigation is an analysis of the effect on the individual radiated pressure fields of the sources axial and radial location. In this investigation we detail the circumstances when the open and ducted radiation are similar, and consequently allowing the effect of the duct to be neglected in acoustic modelling.

Abstract
his paper concerns the acoustic radiation from open and ducted sources. Many rotors and fans utilise ducts to improve air flow and quality. In this paper, we relate the radiation of ducted and open sources to form an open-to-ducted transfer function, capable of predicting the effect of shrouding an open source in a duct. A key part of the investigation is an analysis of the effect on the individual radiated pressure fields of the sources axial and radial location. In this investigation we detail the circumstances when the open and ducted radiation are similar, and consequently allowing the effect of the duct to be neglected in acoustic modelling.
