EASE JR is suited for projects that deal only with the sound system or that have well-controlled room acoustics that can be treated statistically. It requires the least amount of time and data to obtain answers about the performance of the sound system and the acoustic characteristics of the venue.
- Calculation method
-
To calculate reverberation time, EASE JR uses a statistical approach based on the Eyring equation. This method assumes that the sound field inside the room is diffuse. This type of sound field is common in rooms where the absorption is homogeneously distributed over the surfaces and where the geometry is approximately convex and does not propagate sound energy in specific directions or areas.
- Typical use cases
-
- Planning and design of sound reinforcement systems for direct field coverage, delay alignment and spatial audio
- Acoustic design for rooms with controlled absorption and relatively simple shape
- Investigating the performance of the sound system in the room and related quantities like STI, Total SPL, or C50
- Verification and improvement of absorption based on a calculated or measured reverberation time
- Initial investigation of general room acoustic properties for more complex rooms
- Auralization of the direct sound to study the audible performance of the sound system at different listening positions
- Typical rooms/venues
-
Indoor: rooms with relatively high, evenly distributed absorption and rather simple shape like multi-purpose rooms, lecture halls, convention halls, churches, certain kinds of classrooms and office spaces
Outdoor: concerts in rural locations, i.e., in the open field
For more advanced investigations and more complex project types, as well as complete auralizations, it is recommended to consider EASE Standard or EASE Pro.
