EASE Evac - Fast & Easy Design and Simulation of Mass Notification Systems

Software

There are numerous areas where mass notification systems are employed. These include applications such as education, healthcare, entertainment, retail, transportation & travel, and industrial facilities, to name a few. In other words, any facility where large numbers of people congregate. In this context, electro-acoustic devices such as speakers and horns are typically required for delivering the message.

To evaluate how to place and aim these speakers and horns in a venue, EASE Evac allows quick and accurate creation and analysis of designs. This ensures that the acoustic information is provided reliably and in the desired quality.

EASE Evac is a 3D simulation software solution developed by AFMG® specifically designed to meet the needs of the design and simulation of mass notification systems (MNS) and especially voice address systems. It offers:

  • Intuitive room entry in just minutes.
  • A large database of widely used loudspeaker brands and products.
  • Auto-arrange option to quickly add a large number of ceiling loudspeakers in a user-defined grid.
  • Simulation of constant-voltage and low-impedance networks including transformer settings.
  • Fast and precise prediction of SPL and SNR as well as STI and CIS.
  • Comprehensive reports for calculation, presentation and installation.

EASE Evac significantly speeds up and simplifies the planning process.

Features

Room geometry entry in a fast and intuitive manner
 

Import of reference drawings

As a basis to draw the room geometry, CAD and image files can be imported as a background picture. Several file formats are supported by EASE Evac for this, such as:

  • SPK - Trimble Sketchup
  • DXF - Autodesk
  • FRD - EASE
  • PNG, JPG, TIFF, ...

The so-called layout maps can be properly scaled and placed in the project.

Room outline drawing

This is one of the many features that make Evac easy to get started with. Simply drag the vertices with the mouse to position them and define the room outline. The precise vertice´s coordinates can also be fine tuned or corrected, if needed.

Measure Tool

Evac´s measure tool is able to not only measure the distance between two points, but also the corresponding time delay, and X- and Y-offset.

Auto-arrange function for ceiling loudspeakers

Ceiling loudspeakers can be automatically arranged based on the room dimensions and a design criterion specified by you.

Import of noise levels

 

Take into account the effect of noise on speech intelligibility

Evac is provided with several noise curve files that can be directly loaded into the application. These include:

  • NCB (balanced noise‐criterion) curves
  • NC (noise criteria) curves
  • RNC (room noise criteria) curves
  • NR (noise rating) curves
  • PNC (preferred noise criterion) curves
  • A-, B- and C-weighted sound pressure level curves

Measured noise levels can be also be loaded into the application and regarded for the simulations.

Reverberation time
 

Eyring reverberation time calculation

Another contributing factor to the reduction of speech intelligibility is the reverberation. Evac computes the reverberation time from a statistical point of view, based on Eyring´s equation. 

For this, to each wall one or more acoustic materials can be easily assigned from a concise database provided with the software. The corresponding absorption coefficients, as well as information about the room volume and surface area, are key inputs for the computation of the RT.

Import of measured reverberation time

The measured reverberation time (1 octave or 1/3 octave values) can also be imported into Evac, and be used for the acoustic simulations. In this way, there is no need to look for suitable materials and assign them to the rooms surfaces.

In addition, the software is shiped with a set of RT curves that can be imported for evaluations and comparisons. 

Speech intelligibility mapping

Mapping of speech intelligibility as:

  • STI (Speech Transmission Index)
  • CIS (Common Intelligibility Scale) and 
  • ALCons (Articulation Loss of Consonants)

Comply with the 5th and latest edition of the IEC 60268-16 standard:

  • Select the speech signal spectrum for the input signal
  • Apply signal masking corrections

The STI standard applies penalties to the intelligibility when the level is about and below hearing threshold, as well as due to masking by lower frequency bands if they are too loud. Typically the STI is increasingly reduced at levels of 40 dB and lower as well as at 90 dB and higher!

Different bandwidth analysis

Analysis in 1/3rd octave, 1/1 octave, 3/1 octave bandwidth or broadband, frequency range from 100 Hz to 10 kHz.

Statistical analysis of coverage


Distribution graph

The distribution graph allows you to investigate the relative amount of mapping points that have a certain level or result value. For example, 33% may show a direct sound level of 85 dB +/- 0.5 dB.

​​In addition, average and standard deviation figures are displayed.

Image
Distribution Graph.


Distribution graph + relative mapping

If the mapping is set to relative, the distribution graph is especially suitable for the evaluation of the coverage evenness. The graph shows the deviation distribution, relative to the average and additionally, specifies the percentage of values.

For example, a typical requirement for a sound system is that 90% of the listening area is within +/- 3 dB of the average level. This can be instantly verified using the distribution graph by switching to relative mapping, and setting the tolerance to +/- 3 dB.

Image
Relative Mapping.


Cumulative distribution graph

This type of graph shows the number of data points in percent that have at least a certain value. 

For example, 85% of the area can have an STI of 0.51 or better, or 90% of the area can have a direct sound level of 92 dB or more. Many regulations refer to such thresholds, which makes the cumulative graph particularly useful.

EASE based calculation engine

Calculation engine based on EASE 4 industry standard for electro- and room acoustic modeling

Analogously to EASE JR version, EASE Evac uses a statistical approach (based on Eyring formula) for the computation of the reverberation time.

This method assumes that the sound field inside the room is diffuse. These kinds of sound fields are more commonly encountered in rooms where the absorption is homogeneously distributed over its surfaces, and where its geometry does not propagate concentration of energy in specific directions.

This simplified approach requires the least amount of time and data to obtain answers about the room’s acoustics and the performance of a sound system in the room. It can be seen as a good starting point for performing acoustical and electro-acoustical simulations.

Expandable databases

Multiple rooms

As it is not uncommon for distributed sound systems to include several rooms, Evac supports multiple rooms within one project.

Supported Brands & Database

Supported Brands Table

Several manufacturers provide loudspeaker data files for AFMG software. The table below provides an overview of all the companies who have provided loudspeaker data, and for which products they are available.

To download these data files, please refer to Loudspeaker Databases, from our Resources page.

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

GLLs for loudspeakers and line arrays available for EASE 4 can be used also for EASE 5-FE. The same applies to latest-generation DLLs. Speaker models based on cluster-type GLLs are not yet supported in EASE 5-FE. Speaker models based on SPK files are not supported in EASE 5-FE.
