Mappings on horizontal and vertical cutting planes visualize the calculation results. Sound source data is given in the EASE GLL format, AFMG’s primary loudspeaker file format.īased on the room and the sources defined, the propagation of sound is simulated. Alternatively, the auto-arrange functions will quickly ‘install’ a vast number of ceiling loudspeakers in a user-defined grid. Wall- and ceiling-mounted loudspeakers, horns or sirens can be added to the model and may be positioned individually. All calculations are performed in 3D on statistical models by Eyring. Projects can consist of more than one room, each with its own room acoustic, defined by entering the reverberation time or assigning wall materials with their absorption coefficient to the surfaces of the room. Several tools enable a quick modeling from scratch.

The import of images, AutoCAD DXF-format or Google SketchUp files as well as EASE room models simplifies the building of rooms with a complex layout. EASE Evac offers various alternatives for entering the room. This simple approach speeds up modeling tremendously in everyday projects as hallways, foyers, conference rooms or even airport gate areas. In EASE Evac all rooms are defined by a 2D floorplan and a height. The scientific background of EASE Evac derives from the long-term research and development in conjunction with the programming of EASE, the professional electro- and room acoustic simulation software developed by Ahnert Feistel Media Group (AFMG). The latter calculations are based on statistical room acoustics. The 3D simulation software calculates the distribution of direct sound levels as well as total sound levels, the signal-to-noise ratio (SNR) and speech intelligibility (STI, ALCons, CIS). Measure real room acoustics with very good and powerful measurement systemįast to learn the basics, but with endless possiblities to expand the complexity.EASE Evac provides an intuitive tool for designing acoustic mass notification concepts in a room, hall or building complex. Listen to the acoustics in 3d computer models Get very reliable results with the ODEON algorithms Make simulations of acoustics from 3d models ODEON uses the image-source method combined with a modified ray tracing algorithm.

Sound reinforcement is easily integrated into the acoustic predictions. Given a 3d-model and materials (surface-properties), the acoustics can be predicted, illustrated and listened to. With the appropriate treatment, outdoor situations can be studied as well. Use the ODEON software for simulating and measuring the interior acoustics of buildings.
