I'm looking to create software which will simulate the overall effect of different styles, sizes and openness of speaker grills on the audio received by the listener. So far I have the following potential effects:
- comb filter which would simulate reflections of sound back into cone.
- helmholtz for additional audible harmonics that are created
- chuffing with bass speakers?
- absorbsion by grill?
It's my understanding that the most noticeable effect is that the grill acts as a low pass filter. How could I calculate the frequency response of the filter based on knowledge of the system components?
