The benefits of using Computer Aided Acoustic Software

Computer-aided acoustic software are software applications and tools specifically designed to assist in various aspects of acoustic design, simulation, analysis, and measurement. These acoustic software packages use the computational power of computers to understand and manipulate acoustic phenomena.

Some of the features of computer-aided acoustic software are:

Acoustic Modeling and Simulation:

Engineers and researchers create virtual models of acoustic environments, such as theatres, buildings, or outdoor spaces. The models simulate sound propagation, with reflections, diffraction, and other acoustic phenomena. The simulated results help predict the behaviour of sound in different scenarios and assist in optimising acoustic design.

Room Acoustics Analysis:

Acoustic software can simulate the acoustic characteristics of rooms and spaces. One can then analyse and determine reverberation times, speech intelligibility metrics, and predicted sound quality. This analysis assists in optimising room acoustics for specific applications like concert halls, auditoriums, or recording studios.

Sound System Design:

Software tools also simulate sound propagation and aid in the design of sound reinforcement systems. Loudspeaker placement, coverage patterns, and predictions of sound distribution can all be analysed and greatly assist in optimising audio system performance in various venues.

Acoustic software can simulate noise sources, predict noise levels, and assess the impact of noise on the environment or human receptors. It helps in designing noise control measures, such as barriers or enclosures, and evaluating their effectiveness.

Virtual Acoustic Reality:

Some advanced software applications provide virtual acoustic reality, where users can experience simulated auditory environments through headphones or immersive audio systems. VAR allows for subjective evaluation of acoustic design, virtual reality simulations, and auralization of spaces.

Acoustic software often includes tools for capturing, processing, and analysing acoustic measurements. Frequency responses, sound pressure levels, sound quality metrics are evaluated and the acoustic performance optimised.

CATT Acoustic Software – (Computer-Aided Theatre Technique) is the Computer Aided Acoustic Software used by Acoustic Worx.

CATT-Acoustic is a software package used for predicting acoustic performance in an air space; whether in an existing building or at the design stage of a new project. A pair of headphones can be used to listen to predicted audio at any seat in a church or auditorium when a building is still in the design stage.

This is called digital binaural auralization which Catt does by convolving an audio file with a predicted time response. Firstly a 3D model is generated to predict octave-band echograms by assigning frequency dependent acoustic properties to all internal surfaces.

Loudspeakers are inserted with source information to accurately predict the coverage and performance of the airspace. Catt-Acoustic features TUCT analysis software to calculate acoustic prediction parameters. TUCT includes early reflection and diffraction analysis in its calculations by taking into account reflections from small surfaces which are modelled using facets, an example being curved surfaces on ceiling diffusors.

Using different algorithms prediction can determine reverberation times, speech intelligibility, and other metrics as defined in ISO3382.

Catt is a very powerful tool used in Architectural Acoustics as well as sound system design. Cat Acoustics was used in the following recently completed projects:
