Numerical case-study on the development of acoustic equi- valent source models for use in sound synthesis methods

چکیده
Sound synthesis methods aim at the auralization of the sound produced by a physical sound source as it is heard by a listener at an arbitrary location. In order to suit the synthesis approach, the physical source is represented by an acoustic equivalent source model which behaves similar in the far field. However, it is not straightforward to determine the number, the position, the type, . . . of source descriptors needed in the equivalent model for achieving a certain model accuracy. Moreover, the quantification of the source descriptors is a very difficult task. This paper presents the results of a numerical study on some equivalent source models and quantification techniques used to model a cavity backed plate. The study serves as input for the experimental validation that is currently being performed at the K.U.Leuven.

Effect of porosity on the characteristics of underwater acoustic sound absorbers using theoretical models
Porous materials have good acoustic damping characteristics over a wide frequency range. As for sound waves, many small-scale pores in the coating materials can convert underwater-coating to rough surfaces. The main property of porous absorbents is their resistance against incident sound wave that leads to damping effect. From a physical point of view, damping occurs due to friction between flu...
متن کاملInvestigation on acoustic behavior of acoustic porous absorbers to absorb sound energy and transmission loss index
In this study, the acoustic properties of porous absorbents with different porosity levels have been evaluated using different mathematical models. These models use one or more parameters of materials for calculating acoustic characteristics. In all of these models, materials are considered as equivalent fluid and reactionary characteristics have not been taken into account.
متن کاملAcoustic Model Identification Using Inverse Model
Sound measured at various points around the environment can be evaluated by a series of multi-pole sources and their acoustic strength can be acquired. In this numerical study, a method, called the inverse method, was examined to achieve this goal. A variety of arrangements of different sources were considered and the acoustic strength of these sources was acquired. Through the application of t...
متن کاملUse of Stochastic Turbulence Models in Jet Acoustics
There are many approaches to determine the sound propagated from turbulent flows. In hybrid methods, the turbulent noise source field is computed or modeled separately from the far-field calculations. To have an initial and quick estimation of the sound propagation, less computationally intensive methods can be developed using stochastic models of the turbulent fluctuations. In this paper, ...
متن کاملExperimental study and modelling of date palm fibre composite acoustic behaviour using differential evolution algorithm
Background and aims: In recent years, in most countries of the world, the provision of a calming environment without disturbing noise has become a need, which has subsequently led to significant growth in noise control techniques. It is now well documented that prolonged over-exposure to the excessive levels of environmental noise not only induces disabling hearing impairment but also contribut...
