Frequency Limits of microphone array

[Sri Chaitanya Durga Prasad Mojjada]

Hi everyone,

Is there a way for us to find the frequency limits of the microphone array?

How can I know in which frequency range my microphone array works?

Also is there any way that I can understand more about irregular microphone array design rather than standard rectangular , cirular or spiral arrays?

How can I do that with acoular?

Thanks ,

Chaitanya.
