Giant Voice Applications & Design
The increase in Emergency Communications and Mass Notification Systems has increased the need for intelligible voice and audio communication, both indoor and outdoor. This presentation will focus on the guiding principles of mass notification design. This includes the design reliability, code and standards re-quirements, identifying the AHJ, and differences between high-power and medium power loudspeaker arrays. It will help the attendees walk through the design criteria, using acoustic models, and determining overall loudspeaker layout. It will help look at different solutions that can provide cost savings based on various design solutions. This presentation will hopefully help you think outside the box and look for the best solutions based on your situation.
