These results are shown as broadband or frequency dependent mappings with user–defined frequency ranges between 1/3 octave and 3 octaves, absolute or relative values, and A-weighted or non-weighted. 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 Trimble 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). Extensive reports for calculation, presentation and installation.Loudspeaker data for all leading brands.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). This makes EASE Address a generic software.EASE Evac provides an intuitive tool for designing acoustic mass notification concepts in a room, hall or building complex.

Thus, additional loudspeakers can be introduced at any time by additional configuration files, already existing loudspeakers can be updated, without changes to a single line of code in the software. A GLL configuration file allows the definition of the loudspeaker properties in an ASCII text format.
Outstanding is that it is not fixed to a single product. The applicability of EASE Address is quite extended compared to conventional 2D ceiling loudspeaker simulation software. The purpose of EASE Address is to provide both, the end user, who needs to quickly develop a simple design for a ceiling loudspeaker system, as well as the developer, with a tool that allows the easy and quick prediction of the system performance in a given hall.
It only considers the direct field, created by the addition of the sound contributions of the individual loudspeakers. EASE SpeakerLab is a software used to create system definition files in the GLL format to describe the geometrical and acoustical properties of a ceiling loudspeaker.ĮASE Address is a software that allows the modeling of acoustic sources, in particular distributed loudspeaker systems, in two dimensions.
