10. Extensive Ray Tracing Capabilities
Local Decay Times - is a confidence-checking function that uses Ray Tracing to provide a means of quickly checking the RT at various spots in the room to verify the accuracy of the RT time provided by Eyring or Sabine RT formulas. The Eyring or Sabine formulas used by both EASE and EASE JR to develop RT (reverb decay time) values for certain measures are based on a model’s volume and absorption characteristics. These generalized mathematical formulas include assumptions that don’t apply to every room and the accuracy of their predictions varies from room to room. The formulas also develop only a single set of RT values for the entire model while an actual room’s RT varies from one location to another.
Mapping with Reflections – Enhanced AccuracyMapping With Reflections uses Ray Tracing to develop local RT figures, which are then fed back into the mapping calculations to improve prediction accuracy.
Local Ray TracingLocal - saves time by using ray tracing “snap shots” to quickly identify problem areas that need more detailed investigation using the Acoustical probe.
Acoustical Probe - The Probe is a virtual measurement microphone that use Ray Tracing Impact Studies to obtain detailed time, magnitude and frequency information for any point in an EASE map. The Probe is also used to view ray tracing impact files and to create virtual Room Impulse Responses for acoustical evaluation.
EASE offers two different methods of creating Impact Studies. Both use ray tracing to register and store data on all rays impacting a specific location within the model over the length of the investigation. Data stored for each ray, at each frequency, includes arrival time, energy (SPL) level and direction (arrival angle).The Acoustical Probe is then used to calculate, map and display the detailed acousticaldata required for discovering optimal solutions in problem areas.
Available displays include:
Reflectograms (EFC/ETC displays)
Pulse Directionality (Hedgehog) displays
Schroeder RT Times
Modular Transfer Function (MTF)
STI Intelligibility Projections
Impulse Response Files
