1. A method, comprising:
generating, from an audio source within an audio range, using a microphone array, a plurality of microphone input signals including a first microphone input signal and a second microphone input signal;
determining a first output associated with a first microphone in the microphone array, wherein the first microphone input signal corresponds to the first output of the first microphone in the microphone array;
determining a second output associated with a second microphone in the microphone array, wherein the second microphone input signal corresponds to the second output of the second microphone in the microphone array;
determining a likelihood of a set of detrimental effects based at least in part on a comparison of the first output and the second output;
selecting a particular detrimental effect on the microphone array from the set of detrimental effects based at least in part on the likelihood of the particular detrimental effect; and
providing, via an interface, an instruction associated with the particular detrimental effect on the microphone array.
