Computer modelling and simulation of sound field in 24 rectangular concert halls
Extensive acoustics computer simulations has been made using Odeon computer simulation software. From 300 to 850 measurements positions have been analysed in 24 rectangular rooms representing “shoe‐box” type concert halls with volumes of 8 000m3, 12 000m3 and 16 000m. In total 14 000 receiver positions have been analysed. For each receiver position eight objective measures […]
Relationship between room shape and acoustics ofrectangular concert halls
Extensive acoustics computer simulations have been made using Odeon computer simulation software. In 24 rectangular rooms representing “shoe‐box” type concert halls with volumes of 8 000 m3, 12 000 m3 and 16 000 m3 from 300 to 850 measurements positions have been analysed. Only room averaged objective measures are considered here, in particular Clarity (C80), Strength (G) […]
Assesment of Acoustical Characteristics for Historical Baths (Hammams)
Comprehensive studies are necessary to better understand the original acoustical characteristics of historical baths (hammams) in order to discover the historical technologies establishing acoustical properties in these structures and keep their proper functioning for long periods of time. The study was conducted on five historical Turkish hammams, belonging to the Ottoman period. Their acoustical performances […]
The acoustic design of the Elisabeth Murdoch Hall, Melbourne, Australia
The Elisabeth Murdoch Hall is a 1000 seat recital space which will be completed in the latter half of 2008. The overall geometry is based on a classical shoebox shape to provide acoustic excellence although the internal appearance is wholly contemporary. The walls and ceiling of the hall are clad in timber panelling which is […]
Modelling Airborne Sound transmission between coupled rooms
A new method has been developed for the calculation of transmission through walls, including auralization in the receiving room. This has been made as an option in the room acoustic simulation software Odeon version 9. Transmission through multiple walls can be investigated; even walls with different materials on either side and with thickness can be […]
Auralisation of Concert Halls using Multi-source representation of a Symphony Orchestra
The multi-source auralisation technique is based on anechoic recordings of each single instrument in the symphony orchestra. Although the accurate synchronisation of the instruments cannot be perfect, the advantages of this technique include increased realism in terms of localisation and apparent source width, and the possibility to compare different orchestra setups and the interaction between […]
Auralisation of a symphony orchestra with odeon – the chain from musical instruments to the eardrums
Auralisation is a very complicated technique, the quality of which depends on every single part in a long chain, starting with the anechoic recording of the sound to be used as input, continuing through the room acoustic simulation that connects the source and the receiver, and ending in the presentation of the sound to the […]
Validation of a loudspeaker-based room auralisation system with speech-intelligibility measures
A novel loudspeaker-based room auralization (LoRA) system has been proposed to generate versatile and realistic virtual auditory environments (VAEs) for investigating human auditory perception. This system efficiently combines modern room acoustic models with loudspeaker auralization using either single loudspeaker or high-order Ambisonics (HOA) auralization. The LoRA signal processing of the direct sound and the early […]
A loudspeaker-based room auralization system for auditory perception research
A loudspeaker-based room auralization (LoRA) system has been recently proposed which efficiently combines modern room acoustic modeling techniques with high-order Ambisonics (HOA) auralization to generate virtual auditory environments (VAEs). The reproduction of the distance of sound events in such VAE is very important for its fidelity. A direct-scaling distance perception experiment was conducted to evaluate […]
