EASE Standard is suited for projects where the room acoustics are still relatively controlled, but where early reflections are playing an important role, either beneficial or detrimental. It provides advanced acoustic assessment methods to direct and enhance first-order reflections as well as to analyze and resolve related acoustic obstacles. Users gain a more accurate picture not only of the performance of a loudspeaker system, but also of the general behavior of the sound in a room.
- Calculation method
-
EASE Standard calculates the impulse response at specific locations in the room by using ray-tracing algorithms for the early part of the response and by adding a statistical tail for the late part. This approach is generally sufficient for rooms where one would not expect discrete reflections of significant energy in the later part of the impulse response. This method is recommended for rooms where the sound reflected by side walls, ceiling, or backwall into the audience has to be controlled. It applies to rooms with relatively complex geometries and possibly uneven distribution of absorption, which can lead to local differences in received early sound energy or audible echoes. The reverberation component of the room response, however, is assumed to be statistical.
- Typical use cases
-
- Local analysis and visualization of reflections in the room, such as arrival, decay time, level, or frequency response, to examine echoes, distinct reflections, and focusing effects
- Designing sound systems in acoustically challenging venues
- Detailed evaluation of quantities like STI, Total SPL, or C50 using mappings based on statistical assumptions extended by early reflections
- Optimizing the reflective behavior of ceiling structures and side walls as well as reflection angles of acoustic clouds and panels
- Creating instructive auralizations of echoes and early reflections
- Typical rooms/venues
-
Indoor: rooms with potentially uneven distribution of absorption and relatively complex geometry like studios, class rooms, lecture halls, multi-purpose, ballrooms, theatres, other relatively dry entertainment venues, convention halls, malls, conference rooms
Outdoor: concerts in urban locations, especially considering building facades
For more advanced investigations and very complex project types, as well as precise auralization results, it is recommended to consider EASE Pro.
