  • How to Adjust Room Acoustics to Multifunctional Use at Music Venues

    Multifunctional venues such as local culture centres have to be flexible to host many different kinds of concerts, theatre shows, and various other events. Additionally, many existing venues such as theatres, concert halls, and even opera houses need to present shows which are not typical for their purpose. This situation caused a strong need to change the acoustic parameters of the venue between different types of events. The paper presents a few ideas on how to meet this need, based on several realized music venues. Technologies used to change room acoustics are explained, as well as final results taken by acoustic measurements.

  • Computing room acoustics with CUDA - 3D FDTD schemes with boundary losses and viscosity

    In seeking to model realistic room acoustics, direct numerical simulation can be employed. This paper presents 3D Finite Difference Time Domain schemes that incorporate losses at boundaries and due to the viscosity of air. These models operate within a virtual room designed on a detailed floor plan. The schemes are computed at 44.1kHz, using large-scale data sets containing up to 100 million points each. A performance comparison is made between serial computation in C, and parallel computation using CUDA on GPUs, showing up to 80 times speed-ups. Testing on two different Nvidia Tesla cards shows the benefits of the latest FERMI architecture for double precision floating-point computation.

  • Intelligent and adaptive acoustics in buildings via blind room acosutic parameter estimation

    From an architectural acoustics perspective multi-purpose enclosures in buildings with variable and adaptive acoustics are difficult to achieve. However, such spaces may become more feasible using amplified sound with the aid of signal processing and blind room acoustic parameter estimation techniques. The paper proposes the use of room acoustic parameters extracted from received speech or music to determine the amount of additional artificial reverberation so that the desired acoustics can be achieved. The use of blind estimation from naturally occurring source enables on-line and adaptation to various changes in the space and delivers the acoustics as required for diverse uses of the space.

  • Directional source modeling in wave-based room acoustics simulation

    Wave-based modeling in room acoustics and virtualisation applications constitutes an alternative to geometric or ray-based approaches; finite difference time domain (FDTD) methods, defined over regular grids, are an excellent match to parallel architectures. Acoustic sources are typically included as monopoles or collections of monopoles, realised, in an FDTD setting, as a forcing of a single grid point. This paper is concerned with more general representations of multipole point sources, based on spatially bandlimited approximations to the Dirac delta function in 3D. As such, it becomes possible to incorporate, in a flexible manner, multipole sources without regard to direction or alignment with an underlying grid. Numerical results are presented in the case of the acoustic monopole, dipole and quadrupole.

  • Weighted Reduction of Impact Sound Pressure Level for a Floating Floor, According to ISO Standard and Laboratory Measurements

    Insufficient impact sound insulation of floors in present architecture has been a frequent issue reported by owners of flats sold in the past few years. Floating floor is one of a few ways to improve this kind of insulation, as well as to increase the airborne sound insulation of the ceiling. A revision of EN ISO 12354-2 standard published by the end of 2017 brings a new formula used to calculate weighted reduction of impact sound pressure level for floating floor screeds made of sand/cement or calcium-sulfate. The aim of this study is to point out and discuss the differences between the new and old formula, both compared to laboratory measurements carried out in the Building Research Institute (ITB).

  • The acoustics of the traditional theater in South China: The case of Wanfu theatre

    The interplay of Wanfu theatre is remarkable in traditional Guangdong Opera performance. It is located at the ancestral joss house in Foshan, where is the cradle land of Guangdong Opera. As one of the well-preserved gorgeous and elaborated historical architecture in South China, it is not only important to the architecture history, but also to the opera performance. It is nowadays frequently performance space for Guangdong opera. The architecture details are described in this work, especially with a great detail of the theatre stage. By means of both in field measurements and sound field computer simulation with room acoustics software ODEON, the most important features of the sound field in Wanfu theatre are clarified and discussed. The measurement results of acoustical parameters EDT, G and C<sub>80</sub> are compared with simulated values. Some discrepancies of strength G are found in the side balcony between the measurement results and the simulated values.

  • Underwater acoustics for ecosystem research: Synthesis of current knowledge and current advances and perspectives in Northeast Brazil

    While used in routine for fish biomass assessment in a variety of marine laboratories, underwater acoustics have an unrealized potential for multi- component observations of abiotic and biotic ecosystem characteristics. A growing number of studies is taking advantage of recent improvements (e.g. multifrequency, broad band echosounders) to simultaneously characterize physical structures (e.g. thin layers, internal waves, eddies) and organisms (from zooplankton to whales) patterns of distribution across scales from meters to thousands of kilometers. These progresses open a variety of perspectives for understanding complex processes. In this context, the aim of this short note is twofold: (i) provide examples of the application of `ecosystem acoustics' to describe and quantify complex processes; and (ii) present the current advances and perspective of the application of ecosystem acoustic in Northeast Brazil.

  • Design of Acoustic Chamber for Loudspeaker Measurements

    The design of a small anechoic chamber dedicated for measurements of the acoustical parameters of hi - fi loudspeaker systems is presented in the paper. Sound insulation, noise from technical equipment and acoustics of the room are discussed. The laboratory consists of three main rooms: anechoic chamber, control room and equipment room. The chamber of 140 m3 effective inner space with full anechoic condition from 100 Hz is planned as “box in box” construction. The acoustics of the measurement room allows for loudspeaker measurements according to EN 60268-5 standard. Sound absorption of acoustical wedges made from polyurethane foam and rockwool is also measured and compared. The disadvantages of foam wedges are discussed. The new idea of loudspeaker-microphone-walls setup that allows for measurement in the frequency range above 80 Hz is proposed. This frequency lies below the chamber cut-off frequency. The applied technical solutions of sound insulation are also discussed.

  • Identification of unknown vibrating pressures in a three-chamber unit using a Computational Inverse Acoustics Method

    Knowing the properties of vibrating systems is essential in design, controlling and reducing undesirable vibration. Direct measurements in some cases are dangerous or difficult; therefore, several other methods such as Near Field Acoustical Holography, Acoustic Array Techniques, Acoustic Transfer Matrix and Inverse Numerical Acoustics are recommended. This paper aims to provide an efficient method using Computational Inverse Acoustics to identify time history of applied pressures in a vibrating structure by measuring pressure at several points near the structure in surrounding air. This procedure is based on inverse analysis and pre-, during- and post-analysis regularizations are used to reduce the amount of the errors. Computational Inverse Acoustics Method can use in situations that the locations of applied pressures are out of reach, have a high temperature or have a special shape. To solve the problem, variety of different subjects such as acoustics, fluid and solid mechanics, vibrations, inverse analysis, regularization, optimization, fluid-structure interaction and numerical methods should be considered.

  • Finite-difference time domain method source calibration for hybrid acoustics modeling

    Finite-difference time domain methods are commonly used for acoustics modeling of enclosed geometries. For large spaces and high frequencies, the computational requirements become prohibitive in practical use. Thus, geometric acoustics algorithms are used in those cases. The results of these two classes of algorithm can be combined to model the full acoustic response. To allow direct mixing of the results, the source strengths should be calibrated. This paper derives calibration factors for various finite- difference time domain methods. It is shown that the modelled acoustics responses can then be easily combined to synthesise wide-band hybrid responses.
