Horizontal Sound Field Reproduction with Point Sources using Distributed Constraints
A preliminary investigation is presented of horizontal sound field control using a rectangular array of spherical wave driving sources, with focus on wide area plane wave reproduction. Comparison is made between Wave Field Synthesis and a method based on distributed pressure and velocity constraints. Advantages of the second approach are discussed, and modifications of the both methods are prop...
متن کاملUsing Boundary Element-Based Near-field Acoustic Holography to Predict the Source Pressures and Sound Field of an Acoustic Guitar
(Near-field Acoustic Holography, Audio Production, Guitar) In recording studios, the placement of microphones to record an acoustic guitar is very much subjected to trial and error and audio engineer preference. In order to make more informed microphone placement decisions, Near-field Acoustic Holography is used to study the sound pressures of the guitar. This technique involves solving the int...
متن کاملNumerical study on the acoustic field of a centrifugal fan and the tonal noise sources
The widespread use of squirrel cage fans, especially in ventilation and home and industrial environments, has led to the formation of many research efforts to improve performance and reduce the sound produced by this type of fan. In the literature, the most important factor in generating sound in this category of fans is the confrontation between the rotor exit flow and the volute of the fan. I...
متن کاملCommunity Response to Multiple Sound Sources: Integrating Acoustic and Contextual Approaches in the Analysis
Sufficient data refer to the relevant prevalence of sound exposure by mixed traffic sources in many nations. Furthermore, consideration of the potential effects of combined sound exposure is required in legal procedures such as environmental health impact assessments. Nevertheless, current practice still uses single exposure response functions. It is silently assumed that those standard exposur...
متن کاملEffect 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...
