ARCHITECTURAL AND ELECTRO ACOUSTICS CALCULATION SOFTWARE “AFMG EASE 4.4”

Ease is a software package designed for acoustic consultants, sound recording designers and researchers. It provides vast opportunities to create, analyze and improve architectural and electro – acoustic systems.

Software EASE with its additional modules AURA and EARS allows the user to foresee the best solutions by setting the critical points and choosing the best lay out even in early design stages. All calculations are carried out in the 3D model which minimizes the risk of errors because all the solutions and tasks are rendered graphically – in real time environment.

Since the development of software in 1990, EASE became a global standard in terms of calculations for architectural / electro – acoustic spaces. When creating a model, information can be imported from various CAD environments, different acoustical parameters can be set for every surface, user can choose various parameters for sound sources and receivers etc. Calculations can be carried out for essential acoustical parameters – RT, EDT, C80/C50, STI and others. Results are given graphically and statistically; it is also possible to “listen” to the spaces being analyzed using a software extension.

SOUND INSULATION PARAMETER CALCULATION SOFTWARE FOR VARIOUS CONSTRUCTIONS “INSUL”

INSUL is a software package used for predicting the sound insulation of walls, floors, roofs, ceilings and windows, impact sound insulation between floors and rain noise on the roof. The program can make good estimates of various parameters in a few accuracy levels for use in noise transfer calculations or acoustical design or specification. Calculations are carried out according to ISO 717, ISO 140-18, ASTM E492 and E413 standards.

INSUL is being developed and improved for more than 15 years by Marshall Day Acoustics – a company based in New Zealand. During that time the software became widely known among acousticians and constructors all around the world. Mainly due to its good accuracy – the difference between its results and real life calculations does not usually exceed 3 dB.

ARCHITECTURAL ACOUSTICS SIMULATION CALCULATION SOFTWARE “ODEON INDUSTRIAL”

ODEON is a software package dedicated for building and room acoustics simulation calculations and measurements. By setting the geometry of the rooms and types of materials used, it is possible to calculate the room acoustical parameters, sound propagation simulation visualizations and even to listen to the sound emitted in various locations inside the designed room. Calculations in simulations are made according to ISO 3382 standard.

Development of software ODEON began in 1990 in Denmark. Since that year, new versions are being released every year, software is being tested in real life conditions continually, its possibilities are expanded and the reliability is increased. Software is widely used in the whole world by many professional acoustics.

Rooms in which calculations are simulated:
• Concert and opera halls, theaters, churches, rehearsal halls, etc.
• Open plan offices, atriums, restaurants, etc.
• Passenger terminals, public places, etc.
• Industrial and commercial type environments, outside spaces with difficult geometry, etc.

ENVIRONMENTAL NOISE PROPAGATION CALCULATION SOFTWARE “CADNAA”

CadnaA is a software package dedicated to environmental noise propagation calculations, assessments, predictions and visual result presentation. CadnaA is developed by a German company “DataKustik” and is being considered one of the best tools in its field. It is also used in more than 60 countries worldwide.

Software is used in design, science and research, industrial, acoustic and other areas. The main function of this program is to simulate noise propagation (autotransport, rail, air traffic and industrial sources) environment. This can be done in various scales – from one building to the whole city. Software has more than 30 built – in standards, algorithms, object management and visualization tools. “CadnaA” is used to analyze any size national and international noise calculation and noise cartography projects.

Calculations are done by creating a spatial environment model in which road, rail, air transport and industrial noise sources are included. These models can contain buildings, terrain information, sound barriers, bridges, etc. Results can be given graphically in horizontal plane and in vertical plane.

Software is used in order to carry out noise simulations to set the acoustic environment of buildings, to choose appropriate façade, to evaluate the effect of any potential objects to the environment (increased traffic, HVAC systems etc.).

BUILDING SOUND INSULATION CALCULATION SOFTWARE “BASTIAN”

DataKustik Bastian is one of the most effective software packages that is used to calculate building sound insulation according to EN12354 standard.

Software package DataKustik Bastian is used for sound insulation calculations: air borne sound and impact noise insulation between rooms inside a building and also air borne sound insulation through building’s façade. Constructions surrounding the evaluated room and other additional elements are also taken into account when carrying out calculations according to ISO 12354-1, ISO 12354-2, ISO 12354-3 standards.
