Odeon and the Scattering Coefficient

The Acoustics of public squares/places: a comparison between results from a computer simulation program and measurements in situ

In the context of a PhD thesis, in which the main purpose is to analyse the importance of the public square/place (“agora”) as a meeting point of sound and music, with particular regard to its use for concerts (amplified or not), a first step was done, making comparisons between measurement in situ and results coming […]

Evaluation of room acoustic qualities and defects by use of auralization

Auralizations generated by room acoustic computer modeling programs may be used as a tool for evaluation of acoustic qualities and defects, some of which are not easily detected by objective measures. Examples include reverberance, flutter echoes, perceived room size and distance, apparent source width, listener envelopment, and sound propagation in coupled rooms. In order to […]

Acoustic Computer Modelling: A Case Study to Compare Predictions by CATT

This paper presents a case study for the prediction of room acoustic parameters in a church auditorium using both CATT and ODEON software, and compares the predictions with the same parameters determined from analysis using the measured impulse responses. The church auditorium included predominantly hard surface finishes and required acoustic treatment for multipurpose use. Impulse […]

Predicting Acoustics in Class Rooms

Typical class rooms have fairly simple geometries, even so room acoustics in this type of room is difficult to predict using today’s room acoustics computer modeling software. The reasons why acoustics of class room are harder to predict than acoustics of complicated concert halls might be explained by some typical features of these rooms; parallel […]

Perceived Speech Privacy in Computer Simulated Open-plan Offices

In open plan offices the lack of speech privacy between the workstations is one of the major acoustic problems. Improving the speech privacy in an open plan design is therefore the main concern for a successful open plan environment. The project described in this paper aimed to find an objective parameter that correlates well with […]

Agorá Acoustics – Effects of arcades on the acoustics of public squares

This paper is part of a PhD work, dealing with the acoustics of the public squares (‘Agorá Acoustics’), especially when music (amplified or not) is played. Consequently, our approach will be to evaluate public squares using the same set of acoustics concepts for subjective evaluation and objective measurements as applied for concert halls and theatres. […]

Distribution of free path length as an indicator of the room shape and diffusion of reflections

Each geometrical form of room is characterized by a certain specific form of free path length distribution. Its shape can be calculated using the ray-tracing analysis. In the global form of the distribution curve, some characteristic shapes can be recognized which are consequence of room geometrical form at micro and macro level. The distribution of […]
