Modern societies have concerns about growing annoyance due to noise in private dwellings and in commercial worksites. People are exposed to the noise from neighbours, adjacent offices and road traffic which causes disturbance in sleep, physical or mental work impairments. Though ISO (International Standards Organization) provides sound insulation guidelines to protect citizens from the noise exposures, these guidelines do not provide an optimal acoustic satisfaction especially for specific sounds, for example a conversation varying in intelligibility. This work addresses the challenges in traditional sound insulation models, filters and auralization techniques, and establishes an interface between psychoacoustic research and building acoustics in audio-visual VR environments. Improvements are made in sound insulation prediction methods, filters construction and rendering techniques for sound insulation auralization. The virtual building acoustic framework (VBA) is developed toward real-time interactive audio-visual technology, to be able to introduce more realism and, hence, contextual features into psychoacoustic experiments. Listening experiments close to real-life situations are carried which showed that the VBA can be used as an alternate to design test paradigms which help to better analyse and interpret the noise impacts in built-up environments situations depending on the actual activities.

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.

A virtual sound barrier is an active noise control system that uses arrays of loudspeakers and microphones to create a useful size of quiet zone and can be used to reduce sound propagation, radiation, or transmission from noise sources or to reduce noise level around people in a noisy environment. This book introduces the history, principle, and design methods of virtual sound barriers first, and then describes recent progress in research on the systems. Two virtual sound barrier systems, i.e., planar virtual sound barrier system and three-dimensional virtual sound barrier system, are discussed including applications, limitations and future direction discussions.

Avoid Costly Mistakes for Specialists and Non-Specialists Alike Bad acoustics in buildings is a nuisance that is not dealt with easily. The problem applies just as much to open-plan offices and restaurants and to production facilities and transportation stations as it does to performance halls, not to mention homes. It does not merely affect oral communication or enjoyment of music but has quite profound consequences on well-being. Gives Guidance on What to Expect from Design Teams and Contractors Building Acoustics is devoted to practical building and room acoustics, illustrated by numerous examples. It introduces the basics for the different specialists in a design team and for the client and sets out the issues for shared consideration. It guides them in the drawing up of sensible acoustic specifications. It is written for non-specialists and gives an outline of potential problems. It also shows what to consider before the construction stage. It empowers its readers to express their needs to a specialist consultant and to avoid the worst pitfalls. Covers interactions between acoustics and other disciplines Shows through numerous real-life examples the route to understanding and solving the problem Illustrates various points of views through real projects

The book explains sound insulation in buildings at a level suitable for both graduate students and expert consultants. Theoretical models are set out for sound transmission in buildings, with an emphasis on thick and heavy constructions. Thus, the description is not restrained by the common assumption of bending waves which is characteristic of thin plates, only. A general description is provided, with the modal density in the structures as a key parameter. At low frequencies statistical energy analysis is replaced by modal energy analysis. Sound transmission through windows and facades is represented by a model that allows any angle on incidence, including the special case of grazing incidence. One chapter is devoted to the subjective evaluation of sound insulation, particularly noise from neighbours, and how this can be applied in a sound classification scheme for dwellings. Measurement methods in building acoustics are presented with emphasis on modern methods using MLS signals or sine sweeps. The analysis and estimation of measurement uncertainty is discussed in detail. In a final chapter examples of experimental buildings with high sound insulation are explained.
