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 a
