Sound absorption by clamped poroelastic plates.
Measurements and predictions have been made of the absorption coefficient and the surface acoustic impedance of poroelastic plates clamped in a large impedance tube and separated from the rigid termination by an air gap. The measured and predicted absorption coefficient and surface impedance spectra exhibit low frequency peaks. The peak frequencies observed in the absorption coefficient are clo...
متن کاملInteractive Modeling of Tree Bark
There exist many computer graphics techniques which could achieve high quality tree generation. However, only a few works focus on realistic modeling of tree bark. Difficulties lie in the complex appearance of the bark surfaces which are largely determined by their mesostructures. Unlike traditional physical based methods, in this paper, we present an appearance-based method to model tree bark ...
متن کاملSound Vision 2.0: Bark Scale Visualizer
There exist a great deal of visual real-time signal analysis tools and music visualizers ([1], [2], and [3]) whose purpose is to allow a user to gain information that can’t be determined (or can’t be determined easily) through auditory analysis alone. This information can be used in a variety of ways: to notate, mix, and/or inform the composition of music, for example. It was my purpose in the ...
متن کاملSound Absorption in the Workplace
The results are in. Recent studies conducted by an independent testing laboratory show that when it comes to acoustics, commercial cushion makes carpet even better. To specifiers and end-users, it will come as no surprise that properly specified carpet cushion reduces noise when used in a commercial installation. What will be of interest is the degree of improvement that has been quantified in ...
متن کاملA Computational Model for Sound Field Absorption by Acoustic Arrays
In this paper we discuss the sound absorption property of arrays of micro-acoustic actuators at a control surface. We use the wave equation over the half plane for the velocity potential with a boundary dissipation by a proportional pressure feedback law along the half plane boundary. The feedback gain over the array is described by a distributed shape function. We develop a computational metho...
