About EASE Data
Sound system projects are more likely to go to plan when you have a reliable indicator in
advance of how the speaker system will perform in the venue. Turbosound engineers are
able to assist you with your system design using the industry-standard EASE program to
aid in the quest to find the perfect system for the job. Although we cannot replace the
role of an acoustical consultant, we can provide a good indication of system performance
to back up the proposal.
Statistically, more jobs are won and more sales are made when a project has been
properly and scientifically designed, along with the facility to show the client a convincing
visual representation of the finished design. This cuts a large amount of guesswork out of
the process, and is the reason why we actively encourage you to make use of our design
resources to help you or your customers to win that next job. EASE is also a useful tool
for addressing acoustic issues in the venue, for example to justify adding acoustic
treatment to a room such as cladding a wall or balcony face. Having a graphical model
can strengthen the proposal and ultimately ensure a better result.
Overview
EASE (Enhanced Acoustic Simulator for Engineers) is a sophisticated sound system
design tool and acoustic simulation software package for Windows PCs, created by SDA
(Software Design Ahmert GmbH, Berlin). It enables extremely accurate acoustic
calculations to be realised both for indoor venues and outside spaces. In this way
acoustic parameters and properties can be calculated for audience areas or even
particular listener seats. EASE is particularly useful where a large number of speakers
may be used, i.e. in concert halls, stadiums and public buildings.
The EASE application itself is comprehensive and can account for a wide range of surface
properties, i.e. absorption and dispersion and also early reflections, directivity and phase
characteristics. 3D acoustical models can be created for computing parameters such as
RT (Reverb Time), IR (Impulse Response) and SPL (Sound Pressure Level) distribution for
sound reinforcement and speech intelligibility.
There are a variety of module upgrades that enhance EASE’s capabilities, such as AURA
(Analysis Utility for Room Acoustics) which has become a standard for modelling spaces
in three dimensions along with the VISION rendering engine. EASE VIEW loads OpenGL
and Mapping files as used in the design
EARS is an auralisation module that allows the determination of audio quality, and the
comparison of old against new sound system installs, by locating sound sources in the
virtual room, or open air space, using convolving and binaural techniques.
