What type of microphone is sensitive to sounds from a single direction?

A microphone that is sensitive to sounds from a single direction is known as a unidirectional microphone. This type of microphone is designed to capture audio primarily from one direction while minimizing sound pickup from other directions, which is particularly useful in noisy environments or situations where the speaker's voice needs to be emphasized.

Unidirectional microphones typically have a cardioid polar pattern, which means they are most sensitive to sound coming from the front, tapering off in sensitivity to sounds coming from the sides and rear. This characteristic helps to isolate the desired audio source from background noise, making it a popular choice for live performances, broadcasting, and recording.

The other options represent different microphone types or characteristics. Omnidirectional microphones pick up sound equally from all directions, which is the opposite of the unidirectional design. Dynamic and condenser microphones refer to the type of technology used in their construction, rather than directional sensitivity. While both types can be made in unidirectional configurations, the key factor in the correct answer is the sensitivity premise relating to directionality.
