Simulating with S21 arrays

Simulating with S21 Arrays

Simulation with LF Coverage beams from S21 arrays differs slightly than with other array and beam types.

Advanced Beam Simulation with BEM Balloon Technique

The simulation of beams from S21 arrays leverages an advanced Boundary Element Method (BEM) balloon simulation technique. This sophisticated approach provides highly accurate predictions of beam behavior.

To understand the effects of the technique, its useful to know that LF (Low-Frequency) Coverage Beams from S21 arrays are optimized taking into account their surrounding environment. This includes walls, other arrays, and any additional elements that may affect beam performance.

That's why simulating with S21 and LF coverage beams introduces the concept of an acoustic neighborhood, which represents the immediate environment surrounding an S21 array. This neighborhood is crucial to ensure LF Coverage Beams are precisely optimized for their environment, delivering the best possible sound quality. This is the reason that if something changes within the acoustic neighbourhood, the user is presented with a warning to re-optimize their beams.

Handling Changes in the Acoustic Neighborhood

• If an object enters or is removed from the acoustic neighborhood, the system automatically detects the change and a warning will appear. If reoptimization is required, users need to reoptimize the affected beams to ensure they are accurate.

• If the change invalidates the existing LF Coverage Beams, users are prompted to reoptimize their beams.

• Reoptimizing the beams ensures that the beam optimzation remains accurate by incorporating the new state of the neighbourhood around the array.

• Once the object is just passing through the neighbourhood, the warning disappears if no further action is required.

By continuously adapting to environmental changes, the S21 array simulation provides more accurate and reliable results, ensuring optimal LF beam performance in any given space.
