EASE® Standard is able to calculate the impulse response at specific locations in the room by using ray tracing algorithms. You can choose to perform geometrical ray tracing calculations based on the deterministic image model or the stochastic ray tracing method. This way you can get a more accurate picture of not only of the performance of a loudspeakers’ system but also of the general behavior of the sound in a room.
This version of EASE provides an intermediate level of calculations for rooms with more complex geometries and uneven distribution of absorbtion. In these cases you would often be expecting local differences in reverberation or audible echoes.
In addition to the benefits available in EASE JR, EASE Standard is helpful:
- To design sound systems in acoustically challenging venues where not only the reverberant field plays a role, but also strong discrete reflections.
- 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.
- When advanced acoustical evaluations are the focus in order to analyze and solve acoustical problems.
- For local analysis of reflections in the room in a manner similar to positioning a measurement microphone on site. This enables you to become aware of obstacles that could remain hidden without enhanced investigation.
In order to keep calculation times within acceptable ranges, ray tracing algorithms are usually employed only to calculate 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 this later part of the impulse response.
Typical room/venue examples are:
Stadiums and cathedrals (for reflection analyses only)
Auditoriums, lecture halls, traditional churches - In addition to the examples for EASE JR.
