What type of microphone is best for me?
- Noise-Canceling Microphone: This is the most common and widely understood professional and consumer term for a microphone designed to filter ambient noise.
- Noise-Rejecting Microphone: This term is often used within industry circles to describe microphones (particularly dynamic microphones with specific polar patterns) that inherently reject sound from certain directions.
- Active Noise Control (ANC) / Active Noise Reduction (ANR): This refers to the specific technology using one or more built-in microphones and digital signal processing (DSP) to create "anti-noise" sound waves that actively cancel out unwanted, consistent background sounds (like engine hums or air conditioning) for the listener.
- Environmental Noise Cancellation (ENC): This term is typically used for microphones (often in headsets) that focus on cleaning up the audio signal being transmitted, so the person on the other end of a call or recording hears a clearer voice with reduced ambient noise.
- Directional Microphones: Many professional microphones achieve noise reduction through their physical design, using a specific "polar pattern" to capture sound primarily from one direction while rejecting sounds from the sides and rear. Common directional patterns include:
- Cardioid: Picks up sound mainly from the front, excellent for general noise rejection.
- Supercardioid / Hypercardioid: Even more directional than cardioid, offering superior rejection of off-axis sound.
- Shotgun Microphone: A highly directional microphone used for picking up sound from a specific, narrow area, often used in film and video production.
