SIM-AUR模块对安装在普通腔体系统中的电动驱动单元进行数值模拟。与其他模块不同，施加的激励可以是任意长度的任意种类信号（例如测试信号、音乐等）。它使用扩展的集总参数模型来描述整个工作范围内的传输行为；计算出的电气、机械、声学和热状态变量可用于扩展分析，真实的或虚拟的驱动单元和系统数据都可以用作模拟的基础。另外，在不影响模拟换能器系统的情况下，可以分离出明显的非线性效应。将声输出信号中的失真从线性分量中分离出来是该可听化技术的基础，还可以执行双盲A/B比较，并系统地确定可听性阈值。此外，分离出的信号可供进一步分析。
Thermal Operation
This operation is used to calculate the long-term thermal response of the transducer. A time-lapse feature for fast calculation is available. Using the time-lapse technique, the long test state variables, such as the magnet and pole-tips temperature, are approximately determined and can be used for further operations. The “Thermal”-operation must be the first operation of the SIM-AUR module. Every further operation depends on the transducer model and stimulus defined in this operation.
Time Lapse Technique
Example
Auralization
The new auralization technique is used to separate distinct nonlinear effects, such as effects due to nonlinear Bl, Le or Rms or other, without affecting the model state. This separation does not affect the speaker model itself. The separated effects can be used to determine the root cause of the nonlinear distortion. Also, the separated signal can be stored as a wave-file, giving the possibility to easily design auditory experiments to evaluate the impact on audible quality.
The most important objectives are:
- Separation of nonlinear effects without affecting the modelled speaker
- Exploit the main source of nonlinear distortion in the output signal
- Design auditory experiments to evaluate the audible impact of the nonlinear distortion
- Evaluate the audible performance of the speaker at the target application
- Find optimal performance-cost ratio
- Assess distortion ratio in audio signals
