EASE Standard - Product Offer Description

This version of EASE provides an intermediate level of calculations for rooms with more complex geometries and uneven distribution of absorption. In these cases, there often are local differences in reverberation or audible echoes.

EASE Standard is able to calculate the impulse response at specific locations in the room by using ray tracing algorithms. Geometrical ray tracing calculations can be performed based on stochastic methods with image model precision. A more accurate picture not only of the performance of a loudspeakers’ system but also of the general behavior of the sound in a room can be obtained.

EASE Standard is helpful when advanced acoustical evaluations are the focus in order to analyze and solve acoustical problems, like:

  • When the assumptions of Eyring and Sabine formulas for the calculation of the reverberation time are not met, and thus ray tracing algorithms are recommended.
  • For local analysis of reflections in the room in a manner similar to positioning a measurement microphone on site in order to look at arrival time, level, or frequency response. This enables you to become aware of obstacles or issues that could remain hidden without enhanced investigation.
  • For evaluating the spatial characteristics of reflections in detail with respect to their direction of incidence and the sequence of surfaces hit, for any location in the room.
  • For designing sound systems in acoustically challenging venues, where not only the reverberant field plays a role, but also strong discrete reflections or focusing effects.
  • For determining local decay times, i.e., when the reverberation time cannot be assumed the same for all places in the room.

In order to keep calculation times within acceptable ranges, ray tracing algorithms are often employed to calculate only the early part of the room’s impulse response. The so-called “statistical tail” is then computed and used for the later part. This approach is generally sufficient for rooms where you would not expect reflections with considerable energy in the later part of the impulse response.

Typical use cases / room examples are:
All types of projects that can be dealt with in EASE JR as well as rooms with potentially non-uniform diffuse sound fields or increased echo probability, such as stadiums, theaters, auditoriums, classrooms, office spaces, cathedrals (for reflection analyses only), train stations, industrial halls, but also specific churches, and public spaces.

  • For more advanced investigations and types of projects as well as precise auralization results, it is recommended to consider EASE Pro.
  • For specific application scenarios, some users may not yet find all the tools they need in their workflows, especially when they are in-depth users of EASE 4.4. In these cases, it is recommended to consider EASE 4.4 instead of EASE 5. For a detailed overview please have a look at the Feature Comparison EASE 5 vs. EASE 4.
