EASE/ EARS/ AURA

The program package EASE/EARS/AURA contains room-acoustical and electroacoustical simulation software which has been developed in our house since the end of the 1980ies.
This software is our most important verification tool for planning room acoustics and sound-reinforcement systems. It enables not only the simulation of acoustic occurances in rooms which do not yet exist or are to be rebuilt, but also the verification of sound-design solutions, especially in cases where a great number of loudspeakers or arrays are used.
To this effect 3-dimensional acoustical models of the rooms have on principle to be generated in the computer which thereafter can be used for computing a wide range of different parameters like reverberation time, impulse response, sound pressure level distribution in sound reinforcement systems, speech intelligibility, and many more. For optimizing the results it is easily possible to change wall arrangements and wall materials as well as loudspeaker types.
For room-acoustical investigations, computer simulation thus provides essentially more extensive results at a notably reduced expense than the hitherto used physical model measuring technique which it is now replacing almost completely. Only for concert hall design or the room-acoustical layout of complicated room structures these model measuring techniques are still being used.

In fall 1999 ADA Acoustic Design Ahnert launched the Windows-version of EASE 3.0. Delivery of EASE 4.0, complete with Handbook and Tutorial, started at the beginning of August 2002. In fall 2003 the update-version EASE4.1 was finished.

EASE 4.1 is a 32-bit program running on the operating systems Windows 98/NT/2000/XP. Windows 95 is no longer recommended, since it requires special adjustments and certain Service Packages.

Particular features of EASE 4.1 for Windows (in extension of EASE 3.0):

	Enhanced user-friendly windows for menus and desktop, switchable direct access to the different program modules as well as to the appertaining program parameters
	Data format of loudspeakers unchanged 5° and third-octave bandwidth, higher resolutions of up to 1° and 1/24th octave bandwidth can be stored in DLLs and used for computing
	Introduction of complex loudspeaker data including magnitude and phase, direct read-in of measured impulse responses in all usual measuring file formats (TEF20, MLSSA, WAVE, MF, EASERA)
	At present there are Speaker DLLs for line arrays from 12 manufacturers available
	Cluster computing modules for loudspeaker groups for remote-field applications, DLLs for near and far-field calculations
	Data format of materials extended for scattering coefficients, provision of a Wizard for scattering assessments.
	Improved and simplified room entry, no limitation of model components, newly developed DXF Import from AutoCad 3D-volume models, entry of textures
	Simplified room modeling thanks to new tools like extended extruding and by object definition for partial models
	Room visualization by high-resolution rendering technique and textures
	New Hide option as 3D rendering with application of lighting devices
	New room-acoustical computing module AURA based on CAESAR (RWTH Aachen)
	2D and 3D Mapping of all room-acoustic measures according to ISO 3382. To this effect the extended wall-material data bank (Absorption und Diffusion) is used
	New Ray-tracing options in AURA, such as AURA Echogram und AURA Response
	New Visualization options in the calculation of impulse responses
	A new predicted-tail computation ensures a complete impulse response
	Extended features of offline and online (real-timet) auralisation in EARS
	Real-time auralization now as before without additional hardware and in dual channel operation
	No more storage limitations within the bounds of the actual hardware situation

EASE 4.1 for Windows is capable of reading fully compatible all EASE loudspeaker and project data files of EASE 3.0 and converting them into the new format.

A Pentium III processor with 1000 MHz or more is recommended as a minimum not only for the sake of auralisation: EASE is supplied on CD-ROM and requires at least 128 MB RAM as well as 150 MB free space of the hard disc (without data bank which requires 100MB extra).

All features of EASE 4.1 can be obtained complete or as partial options. License is granted now as before by means of a license key which, however, contrary to that of Version 3.0, is obtainable directly via the Internet .
