Combined Wave and Ray Based Room Acoustic Simulations of Small Rooms
Author: Marc Aretz
Publisher: Logos Verlag Berlin GmbH
ISBN: 3832532420
Category : Science
Languages : en
Pages : 221
Book Description
The present thesis establishes a complete framework for the combination of finite element and classical ray based acoustic simulations in small rooms and discusses the inherent challenges and limitations including all aspects of sound generation, sound reflection and sound reception. In this context, the thesis gives detailed guidelines for the best-possible determination of all necessary input data for both simulation domains. The overall potential of the presented combined approach is assessed by conducting extensive objective and subjective comparisons of measurement and simulation results for three types of acoustically relevant small spaces (a scale-model reverberation room, a recording studio and two different car passenger compartments).

Influences of external error sources on measurements of room acoustic parameters
Author: Martin Guski
Publisher: Logos Verlag Berlin GmbH
ISBN: 3832541462
Category : Computers
Languages : en
Pages : 176
Book Description
Correct and precise measurements of room acoustic parameters are of fundamental importance for subjective room impression characterization and for the physical description of the sound field. This thesis investigates external influences on acoustic measurements and errors of the resulting room acoustic parameters. Theoretical models have been developed to predict these errors and indicate the tolerable limits of the described influences. To validate these models, specially designed room acoustic measurements that separate the individual influence factors have been conducted. Noise has been identified as one of the main influence factors and occurs during every measurement. In this thesis the performance of five commonly used stationary noise compensation methods are systematically analyzed depending on the peak signal-to-noise ratio. Impulsive noise that could also occur during the measurement is investigated separately, as the previously introduced compensation techniques are unsuited to handle the influence. The second part of this thesis analyzes the influence of time variances during measurements. Inter- and intra-measurement temperature changes, air movement, and human-sized scattering objects have been investigated.

JBL Audio Engineering for Sound Reinforcement
Author: John M. Eargle
Publisher: Hal Leonard Corporation
ISBN: 1476857059
Category : Music
Languages : en
Pages : 472
Book Description
(Book). This up-to-date book comprehensively covers all aspects of speech and music sound reinforcement. It is roughly divided into four sections: Section 1 provides the tutorial fundamentals that all audio engineers will need, discussing subjects such as fundamentals of acoustics, psychoacoustics, basic electrical theory and digital processing. Section 2 deals with the fundamental classes of hardware that the modern engineer will use, such as loudspeaker systems and components, microphones, mixers, amplifiers and signal processors. Special attention is given to digital techniques for system control and to audio signal analysis. Section 3 deals with the basics of system design, from concept to final realization. It covers topics such as basic system type and speech intelligibility, site survey, user needs analysis and project management. Section 4 discusses individual design areas, such as sports facilities, large-scale tour sound systems, high-level music playback, systems for the theater, religious facilities, and other meeting spaces. The book is written in an accessible style, but does not lack for ample amounts of technical information. It is truly a book for the 21st century!

Acoustics and Noise Control
Author: R J Peters
Publisher: Routledge
ISBN: 1317902998
Category : Technology & Engineering
Languages : en
Pages : 400
Book Description
Acoustics and Noise Control provides a detailed and comprehensive introduction to the principles and practice of acoustics and noise control. Since the last edition was published in 1996 there have been many changes and additions to standards, laws and regulations, codes of practice relating to noise, and in noise measurement techniques and noise control technology so this new edition has been fully revised and updated throughout. The book assumes no previous knowledge of the subject and requires only a basic knowledge of mathematics and physics. There are worked examples in the text to aid understanding and a range of experiments help students use complicated apparatus. Thoroughly revised to cover the latest changes in standards, codes of practice and legislation, this new edition covers much of the Institute of Acoustics Diploma syllabus and has an increased emphasis on the legal issues relating to noise control.

IUTAM Symposium on the Vibration Analysis of Structures with Uncertainties
Author: Alexander K. Belyaev
Publisher: Springer Science & Business Media
ISBN: 9400702892
Category : Technology & Engineering
Languages : en
Pages : 471
Book Description
The Symposium was aimed at the theoretical and numerical problems involved in modelling the dynamic response of structures which have uncertain properties due to variability in the manufacturing and assembly process, with automotive and aerospace structures forming prime examples. It is well known that the difficulty in predicting the response statistics of such structures is immense, due to the complexity of the structure, the large number of variables which might be uncertain, and the inevitable lack of data regarding the statistical distribution of these variables. The Symposium participants presented the latest thinking in this very active research area, and novel techniques were presented covering the full frequency spectrum of low, mid, and high frequency vibration problems. It was demonstrated that for high frequency vibrations the response statistics can saturate and become independent of the detailed distribution of the uncertain system parameters. A number of presentations exploited this physical behaviour by using and extending methods originally developed in both phenomenological thermodynamics and in the fields of quantum mechanics and random matrix theory. For low frequency vibrations a number of presentations focussed on parametric uncertainty modelling (for example, probabilistic models, interval analysis, and fuzzy descriptions) and on methods of propagating this uncertainty through a large dynamic model in an effi cient way. At mid frequencies the problem is mixed, and various hybrid schemes were proposed. It is clear that a comprehensive solution to the problem of predicting the vibration response of uncertain structures across the whole frequency range requires expertise across a wide range of areas (including probabilistic and non-probabilistic methods, interval and info-gap analysis, statistical energy analysis, statistical thermodynamics, random wave approaches, and large scale computations) and this IUTAM symposium presented a unique opportunity to bring together outstanding international experts in these fields.

Perceptual Aspects Of Sound Scattering In Concert Halls
Author: Renzo Vitale
Publisher: Logos Verlag Berlin GmbH
ISBN: 3832539921
Category : Architecture
Languages : en
Pages : 148
Book Description
This work aims to expand the understanding of sound scattering in architectural spaces as well as the comprehension of its influence on the auditory perception in concert halls. The notion of scattering coefficient, which numerically represents the physical phenomenon of sound scattering, constitutes the main paradigm for the entire work. In a first part, the scattering coefficient is introduced in its meaning and implications. New empirical data of scattering objects have been determined and a revised scale model of a reverberation chamber for avoiding measurement accuracies is presented. A case study of classroom acoustics proves the benefit of experimental data on the accuracy of acoustic computer simulations. Furthermore, the implementation of scattering coefficient in different room acoustic computer software is shown by using a concert hall as a case study. In a second part, the relationship between scattering coefficient and auditory perception is explored. Binaural impulse responses have been determined for different scenarios, such as two virtual enclosed spaces and one real concert hall, and convolved with music samples to be used in listening tests. Results from listening tests show how changes in scattering coefficient of diffusing surfaces affect the perception of music among the audience in concert halls.
