EASE 4 - Predecessor software version of EASE 5


EASE 4 is the predecessor of the current software version EASE 5. Version 4 has been in the market for a long time, starting with the release of EASE 4.0 in 2002 and leading up to version 4.4 released in 2014. Over time, EASE 4 has established itself as the standard for electro-acoustic and room acoustic simulations.

With the introduction of EASE 5 in 2022, the development of the EASE software has been brought to a new platform to better meet the expectations of our users, the requirements of modern software and to ensure its future potential. The new software platform offers high usability, practical tools and intuitive workflows, as well as extensive feature enhancements and calculation improvements. It enables acousticians, consultants, designers and installers to work more effectively and comfortably based on proven calculation quality. If you wish to start with the EASE platform, it is highly recommended to do so with EASE 5.

Licenses for EASE 4 are still available for purchase to serve long-term customers who may need an additional user key for their office, who have specific technical requirements, or who desire to add a software module before they upgrade to EASE 5 eventually. Technical support and maintenance services are still available for these cases. However, note that AFMG has announced the end of support for EASE 4 licenses purchased before March 12, 2018

Powerful integration with third-party CAD programs, such as Autodesk AutoCAD and Trimble SketchUp

The EASE IMEX module provides a variety of import and export features enabling you to use your preferred modeling software, as well as to exchange your projects with architects, system integrators, and co-workers.

Data can be moved back and forth easily between EASE and external drawing tools and still maintain specific acoustic information and relationships.

Extensive Acoustic Material Base

Extensible and customizable database with more 700 different acoustic materials, including commercial absorbers

Once the room geometry is defined, the next step towards an acoustical simulation is the assignment of surface materials from the materials database.

At any time you may also create and add materials to the program catalog with the Wall Material Database module or by modify existing data sets. In EASE, acoustic materials are principally defined by a set of absorption and scattering coefficients, given in a 1/3rd octave resolution. 

Examples of acoustic materials.


Additionally, AFMG SoundFlow and AFMG Reflex are fully compatible with EASE. These programs are able to generate new material files and to update existing ones with computed data for absorption coefficients or scattering coefficients, respectively.


AFMG SoundFlow calculates absorption, transmission and reflection of sound in multi-layered structures.

AFMG SoundFlow - Sound absorption and transmission loss simulator

SoundFlow is a simulation software for calculating the absorption, reflection, and transmission of sound by multi-layer structures.

Absorption coefficients generated by SoundFlow can be used in EASE.

AFMG Reflex simulates the scattering of sound on 2D structured surfaces.

AFMG Reflex - Scattering and diffusion simulator

AFMG Reflex is a two-dimensional acoustics simulation software to model the reflection, diffusion, and scattering of a sound wave incident upon a defined geometrical structure.

Scattering coefficients generated by Reflex can also be used in EASE, when it is combined with the AURA module.

Standard Room Parameters

Automatic calculation of standard room parameters

After modeling the room, several measures can be immediately displayed, such as:

  • Room volume
  • Effective surface area
  • Total surface area
  • Mean free path length
  • Mean free path time
  • Average absorption coefficients
  • Material coverage statistics

You can also determine the distance and sound propagation time between any two points in the model.

RT Calculation


Example of Sabine reverberation time

Statistical RT calculation based on the classical equations of Eyring and Sabine

EASE can immediately display the calculated figures based on Sabine or Eyring formulas and use it for a number of related simulations.

RT calculation based on Ray Tracing techniques

The designer is also free to use advanced methods for the RT calculation. These use Ray Tracing techniques in order to compute the room impulse response, which is then used as input to calculate the RT.

Insertion of a Measured RT

Import a real-life measured reverberation time and use it for a number of simulations

AFMG also develops professional measurement software, which can be used to acquire real life reverberation times. This allows e.g. easy comparison between simulation and measurements.

      Standard Mapping

      Standard Mapping - Investigate a comprehensive set of acoustical parameters based on statistical acoustics

      EASE offers a wide set of tools for electro-acoustic and acoustical investigations. Among them is the Standard Mapping feature, which allows a large number of simulations to be performed based on the diffuse field assumptions of statistical acoustics.

      Standard Mapping simulation - STI.
      STI simulation using the Standard Mapping method.

      Standard Mapping makes use of Eyring or Sabine statistical formulas to generate RT figures that will be used to calculate some acoustical parameters, such as the STI (Speech Transmission Index) and the Total SPL. Measured RT data can also be used for this type of mapping.


      A number of acoustic parameters can be simulated with Standard Mapping

      The calculation results are available in 1/3rd octave bands as well as in larger bandwidths. Data can be exported in both text and graphic formats. All of the following parameters can be mapped:

      • Direct SPL
      • Total SPL (Direct + Reverberant sound fields)
      • STI intelligibility measures (according to  IEC60268-16:2003)
      • D/R Ratio (Direct/Reverberant ratio)
      • RaSTI
      • Critical Distance
      • Clarity and Definition Measures (C7, C50, C80, CSplit)
      • Sound Pressure Levels (L7, L50, L80, LSplit)
      • Arrival Times
      • Loudspeaker Coverage Overlap
      • Loudspeaker Aiming
      • ITDG (Initial Time Delay Gap)
      • Articulation Loss (% AlCons)
      • Articulation Index
      • Privacy Index


      The calculations can be performed not only for Audience Areas but also over room surfaces and on specific Listener Seats

      This feature makes it easy to detect potential problems and to analyze representative locations in great detail.

      Statistical tools for enhanced evaluation of simulation results

      Maximum and minimum values, standard deviation, average and distribution graph are some of the statistical resources that you can use to optimize the system performance as well as to illustrate the simulation results.

      In particular, tenders often ask for coverage figures, such as an STI of 0.5 or better for 90% of the area of interest. In EASE, such information is available on a single mouse click.

      Distribution graphs can be viewed for all frequencies and all kinds of acoustic results.

      Reflection Pattern Studies


      Reflection pattern studies with Ray Tracing

      Numerous powerful Ray Tracing tools are offered by EASE, ranging from simple Ray Tracing  as well as Mirror Imaging to an advanced hybrid method, comprising the most accepted techniques worldwide.

      Simple Ray Tracing is an excellent instrument for reflection pattern studies. 

      Reflections over selected surfaces.
      Simple ray tracing on selected surfaces.


      The Ray Tracing technique

      A sound source generates an impulse: a number of particles,  (or rays) are released into the room, propagating at the speed of sound. As they travel, they lose energy due to air absorption, which is especially noticeable at higher frequencies. Eventually a particle hits a room boundary - or an obstacle - loses more energy, and is reflected back to the room, in an iterative process. The program keeps track of each particles path, energy and time, until pre-determined limits are reached (such as propagation time, reflection order or energy loss).

      Ray tracing particles spreading into the room.
      Ray tracing particles spreading into the room.


      You will know exactly when, where and how the rays hit the surfaces

      This enables you to visualize and study the propagation of sound throughout the room. This tool stores information about all reflections so that, ray by ray, you can identify potential geometry problems and evaluate possible solutions.

      • Are those panels correctly angled?

      • Will that rigid back wall cause any problems due to the long propagation path?

      • Do I have to expect flutter echoes in this hall?

      • How does a whispering dome work exactly?

      Ray tracing is also a great presentation tool for demonstrating complicated acoustic problems very intuitively to a client.

      First order reflections over selected surfaces.
      First order reflections over selected surfaces.

      Handy options and expanded functionality can provide you different perspectives

      • Visualize the propagation of particles into the room through the Movie feature.
      • Let the program define the color of a Ray - or particle - by its order, SPL, energy loss or even the color of the reflecting surface . Display only Rays that hit specific surfaces.
      • Show only the Rays emitted within the loudspeakers 3, 6 or 9 dB coverage cones.
      • Analyze each Ray in detail: bounce location at a surface, traveled path, distance, delay, levels from different perspectives. All for each available frequency band.

      For this study usually a relatively small number of rays, e.g. 1,000, is enough.

      Enhanced Standard Mapping

      Standard Mapping with Reflections – One more step towards advanced examinations

      In addition to the ideal reverberant tail used for Standard Mapping, EASE is capable of computing room reflections with different Ray Tracing methods.  Both methods are combined in what we call Standard Mapping with Reflections. 

      This feature is typically used to estimate the consequence of first-order reflections.


      Example of Standard Mapping including first reflections.
      Example of Standard Mapping including first reflections.


      In Standard Mapping with Reflections the undesirable result of that rigid back wall will be much clearer to your eyes!

      • Account for the arrival sequence of first-order reflections
      • Check the possible tonal coloration and comb filtering
      • Evaluate the effect on speech intelligibility
      • Confirm that those panel positions will yield the desired energy distribution!
      • Is there concentration of energy due to that rigid and concave surface? How much energy? Where?


      All calculations available for the Standard Mapping can also be performed here:

      • Direct SPL Total SPL
      • STI intelligibility measures (according to IEC60268-16:2003)
      • D/R Ratio
      • RaSTI
      • Critical Distance
      • C Measures (C7, C50, C80, CSplit)
      • Level Measures (L7, L50, L80, LSplit)
      • Arrival Times

      In-depth Reflection Analysis with Ray Tracing

      Calculations for in-depth reflection analysis – Stochastic and Deterministic Ray Tracing methods

      Ray Tracing Impacts

      The (find) Ray Tracing Impacts feature of EASE is a stochastic approach to model the propagation of sound in the room, giving you the opportunity of performing a comprehensive analysis of reflections that are detected at specific spots – i.e. at Listener Seat locations.

      This approach uses a Monte Carlo simulation method, and in contrast with the simple Ray Tracing technique, here the number of particles (rays) is a fundamental factor, determining simulation accuracy and the repeatability of the results. In many cases 100,000 particles or more are used, although EASE is capable of generating higher figures if needed.   

      Example of Ray Tracing Impacts.
      Example of Ray Tracing Impacts.

      Also in this module you are able to view the ray’s path and information, just as in the simple Ray Tracing feature. But in addition, now you can identify the specific surfaces that are hit before the sound gets to a particular seat, and check the corresponding ray’s minutiae.

      This essential utility registers information for those rays that pass within a meter of a chosen point, e.g. a Listener Seat, and for each point individually. The detailed data – ray arrival time, reflection order, direction of incidence and energy level for all 21 frequency bands covered by EASE - can then be sent to other EASE modules, such as the Probe and EARS programs, so that post-processing, in-depth investigations, analysis of several objective acoustical parameters and critical evaluation of subjective impression can be performed.


      Mirror Image Impacts

      This tool also starts a calculation that looks for all rays that hit specific points (Listener Seats) within the room, so that Impact files for in-depth analysis can be generated and each ray can be analyzed.

      However, unlike Ray Tracing Impacts, Mirror Image Impacts is a deterministic (Image Source) model, leaving nothing to chance!

      100% of rays that would hit a selected seat within a pre-determined cut-off limit are found!

      It is the most accurate approach, also generating exact temporal information.

      This method can be considerably faster than the stochastic Ray Tracing routine, as long as reflections of low orders, or a relatively small number of surfaces are considered. However, the calculation time increases significantly with the reflection order and the number of surfaces. Because of this and the inability of the algorithm to account for scattering effects, large and complex rooms are generally investigated using Ray Tracing Impacts or the AURA raytracing module.

      AURA Module


      The Most Flexible and Accurate Simulation Solution

      AURA comprises a hybrid ray-tracing engine, as well as multi-threading support. It is able to considerably reduce calculation times for obtaining full impulse responses.

      EASE Standard including the AURA module offers the highest quality of calculations, and is the most flexible simulation solution.

      EARS Module

      Add subjective impressions to the design process with accurate auralizations

      Auralization is the process of simulating and making audible the effects of playing a known reference sound, such as program material, through a defined loudspeaker system in a particular space. It allows listening to the room before it is even built. An invaluable tool for the acoustic consultant and sound system designer.


      With EARS you can detect colorations, flutter echoes, spatial distortions, slap-back reflections and more.

      Below you can hear an auralization computed with EARS for the example model shown. The room impulse response calculated with the AURA module was captured at the displayed listener seat position. There was only one loudspeaker on.

      EARS is an extension module for EASE

      Orientation within the room can be provided to the listener both in standard binaural format as well as in Ambisonics B-Format for professional listening rooms. 

      Additionally, EARS includes a number of tools to assist the designer in this task. For instance, with the integrated signal generator it is possible to produce noise signals that can then be mixed in the auralizations, such as Pink Noise, White Noise, Air Conditioning Noise, etc.

      EARS includes mono and stereo convolvers and can perform auralizations either Off-Line (save to an audio file) or in Real Time.

      InfraRed Module

      IR Devices simulation module

      The Infrared (IR) extension module allows you to simulate the performance of infrared communication systems and devices, such as Transmitters and Modulators in a similar way as for sound systems and loudspeakers.

      EASE is capable of simulating the direct radiation of such devices and of computing figures for the signal-to-noise ratio.


      Example of InfraRed simulation
      Example of InfraRed simulation.


      As usual, all the devices are customizable and you can also add your own device characteristics for the simulation.

      For this, EASE provides a dedicated modulator database allowing definition of devices in the narrowband as well as the broadband ranges 2.3, 2.8, 3.3 and 3.8 MHz.

      EASE InfraRed also provides a receiver database. Using specific InfraRed receivers is especially helpful to allow evaluation of local SNR using these specific receivers.

      Loudspeaker Database

      The provision of EASE loudspeaker database takes place with the delivery of the software.

      You can download and update the data files anytime by using Database Update from the Help menu of EASE.

      Some loudspeaker manufacturers distribute the loudspeaker data only through their website or upon request. If you are missing a particular brand in EASE, please contact the respective company directly.

      Please note: The expansion of the EASE 4 loudspeaker database provided by AFMG was discontinued on September 19, 2023.
