For directional mic testing, what types are evaluated?

Directional microphone testing primarily involves the evaluation of different types of microphones that capture sound from specific directions. Omnidirectional microphones pick up sound from all directions equally and serve as a baseline for understanding directional microphones. In contrast, fixed directional microphones are designed to be sensitive to sound primarily from a particular direction, allowing for better isolation of desired audio signals in environments with background noise.

By evaluating both omnidirectional and fixed directional microphones, one can assess the performance characteristics, polar patterns, and sensitivity of these mics. This comparison is critical for understanding how directional mics can effectively reduce unwanted noise and enhance overall sound quality in various audio applications.

While other options refer to different types of microphones, they do not encompass the core distinction between omnidirectional and fixed directional mics, which is crucial in directional mic testing. Therefore, the focus on these two types provides a comprehensive understanding of directional microphone functionality and performance.
