A directional microphone is a type of microphone designed to capture sound from specific directions while minimizing noise from other angles. This feature makes it ideal for situations where the desired sound source is located in a noisy environment, such as during interviews or live performances. Directional microphones are commonly categorized into different patterns, including cardioid, supercardioid, and hypercardioid, each with varying degrees of sensitivity to sound from different directions. These microphones are widely used in various applications, including broadcasting, film production, and public speaking. By focusing on sound from a particular direction, they help improve audio clarity and reduce background noise, making them essential tools for professionals in the audio and entertainment industries.
