Download or read book Soundfield Simulation written by Omar Saad and published by . This book was released on 2004 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past, acoustical consultants could only try to convince the client/architect that with calculations and geometrical plots they could create an acoustically superb space. Now, by modeling the significant acoustical parameters of a design, we can preview a proposed acoustical solution and it is possible to identify the objective parameters that correspond to certain subjective reactions experienced by listeners. The results of a simulation can be presented not only for the eyes but also for the ears. This document explains the basics behind acoustic computer simulation. It includes case studies that analyze and validate numerical parameters and create a sound simulation of a space that allows the listener to subjectively "grade" the acoustical qualities. It includes details on how human hearing uses several techniques to localize sound sources, how we can simulate factors that influence human auditory perception with computer software, and how we can reproduce the listening experience for a space that has not been built. The simulation techniques offer the possibility to use the ears and listen to the acoustics of a room during the design process. Several acoustic problems can be detected by the ears, whereas they may be difficult to express with a parameter that can only be calculated. Using these tools the acoustician can communicate the acoustic consequences of a design to the client/architect effectively. This technique can be used very early in the project to achieve exceptional results.

Download or read book Computational Modeling by Case Study written by Zachary del Rosario and published by Cambridge Scholars Publishing. This book was released on 2024-04-02 with total page 849 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical models power the modern world; they allow us to design safe buildings, investigate changes to the climate, and study the transmission of diseases through a population. However, all models are uncertain: building contractors deviate from the planned design, humans impact the climate unpredictably, and diseases mutate and change. Modern advances in mathematics and statistics provide us with techniques to understand and quantify these sources of uncertainty, allowing us to predict and design with confidence. This book presents a comprehensive treatment of uncertainty: its conceptual nature, techniques to quantify uncertainty, and numerous examples to illustrate sound approaches. Several case studies are discussed in detail to demonstrate an end-to-end treatment of scientific modeling under uncertainty, including framing the problem, building and assessing a model, and answering meaningful questions. The book illustrates a computational approach with the Python package Grama, presenting fully reproducible examples that students and practitioners can quickly adapt to their own problems.

Download or read book Auralization written by Michael Vorländer and published by Springer Science & Business Media. This book was released on 2007-10-27 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first focused and detailed textbook on acoustic virtual reality. Auralization is the creation of audible acoustic sceneries from computer-generated data. The term "auralization" is to be understood as being analogue to the well-known technique of "visualization". In visual illustration of scenes, data or any other meaningful information, in movie animation and in computer graphics, we describe the process of "making visible" as visualization. In acoustics, auralization is taking place when acoustic effects, primary sound signals or means of sound reinforcement or sound transmission, are processed to be presented by using electro-acoustic equipment. This book is organized as a comprehensive collection of basics, methodology and strategies of acoustic simulation and auralization.

Download or read book Second Language Prosody and Computer Modeling written by Okim Kang and published by Routledge. This book was released on 2021-09-13 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents an interdisciplinary approach to the study of second language prosody and computer modeling. It addresses the importance of prosody’s role in communication, bridging the gap between applied linguistics and computer science. The book illustrates the growing importance of the relationship between automated speech recognition systems and language learning assessment in light of new technologies and showcases how the study of prosody in this context in particular can offer innovative insights into the computerized process of natural discourse. The book offers detailed accounts of different methods of analysis and computer models used and demonstrates how these models can be applied to L2 discourse analysis toward predicting real-world language use. Kang, Johnson, and Kermad also use these frameworks as a jumping-off point from which to propose new models of second language prosody and future directions for prosodic computer modeling more generally. Making the case for the use of naturalistic data for real-world applications in empirical research, this volume will foster interdisciplinary dialogues across students and researchers in applied linguistics, speech communication, speech science, and computer engineering.

Download or read book Sound Synthesis Propagation and Rendering written by Liu Shiguang and published by Springer Nature. This book was released on 2022-05-31 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a broad overview of research on sound simulation driven by a variety of applications. Vibrating objects produce sound, which then propagates through a medium such as air or water before finally being heard by a listener. As a crucial sensory channel, sound plays a vital role in many applications. There is a well-established research community in acoustics that has studied the problems related to sound simulation for six decades. Some of the earliest work was motivated by the design of concert halls, theaters, or lecture rooms with good acoustic characteristics. These problems also have been investigated in other applications, including noise control and sound design for urban planning, building construction, and automotive applications. Moreover, plausible or realistic sound effects can improve the sense of presence in a virtual environment or a game. In these applications, sound can provide important clues such as source directionality and spatial size. The book first surveys various sound synthesis methods, including harmonic synthesis, texture synthesis, spectral analysis, and physics-based synthesis. Next, it provides an overview of sound propagation techniques, including wave-based methods, geometric-based methods, and hybrid methods. The book also summarizes various techniques for sound rendering. Finally, it surveys some recent trends, including the use of machine learning methods to accelerate sound simulation and the use of sound simulation techniques for other applications such as speech recognition, source localization, and computer-aided design.
