What is a primary consideration with low profile boundary microphones?

Low profile boundary microphones are designed to capture audio in settings where the microphone's presence should be minimally intrusive. One of the primary considerations with these microphones is their placement, as improper positioning can lead to audio being obstructed by surfaces or other objects. Effective placement is crucial for ensuring optimal sound capture and reducing background noise or interference.

While audio quality is certainly important, low profile boundary microphones are generally engineered to provide good sound quality; hence, it is their placement that can significantly affect performance. Similarly, although appearance might be a factor in certain applications, it is the function and sound capture ability that take precedence in most scenarios. Lastly, while considerations about the power source are relevant, they do not directly relate to the operational effectiveness of the microphone in terms of its acoustic performance. Thus, the placement of low profile boundary microphones stands out as the key factor for achieving the best audio results.
