What is a directional microphone? What are the differences between different directional microphones? When choosing a microphone, I'm sure everyone has the same questions. If you're also worried about choosing a microphone, don't miss this article, which introduces the principles of directional sound pickup and compares the advantages and disadvantages of five directional microphones to help you find the right directional microphone for you.

What is a directional microphone? A brief discussion on the principle of directional sound pickup

microphoneIt is a tool for recording sound, but it may also record unwanted noise and ambient sound at the same time. Therefore, when designing microphones, they are usually designed to meet different needs.Adjust the sensitivity range of the sound, that is, the directionality,Help users accurately record the sounds they need.

A Complete Introduction to 5 Types of Directional Microphones | Understanding Which Type is Best for Different Situations

According to the different sound sensitivity of the microphone, directional microphones can be roughly divided into the following 5 types, which are introduced in detail below:

Directional microphone type 1: omnidirectional microphone

• Sound sensitivity: Highly sensitive to 360-degree sound.

   

• Applicable scenarios: occasions where many sounds need to be recorded at once, such as indoor interviews.

   

• Advantages: All sounds can be recorded at once without having to adjust the microphone position.

   

• Disadvantages: easily disturbed by noise and ambient sound.

Directional microphone type 2: Bidirectional microphone (8-shaped direction)

• Sound sensitivity: It can evenly record the sound from both ends (0 degrees and 180 degrees).

   

• Suitable for recording two sounds simultaneously, such as a two-person interview, where both voices can be recorded in a balanced manner; or when singing and playing a guitar, where both vocals and instruments can be recorded simultaneously.

   

• Advantages: Natural sound, suitable for recording two sound sources at the same time.

   

• Disadvantages: If the sound source is too close, popping sound may occur.

Directional Microphone Type 3: Cardioid Microphone

• Sound sensitivity: It is a unilateral directional microphone that focuses on recording the sound source in front of the microphone while suppressing noise from the back and sides.

   

• Applicable scenarios: Often configured as a headphone microphone, it is also suitable for recording the sound of musical instruments in live performances.

   

• Advantages: Not easily affected by noise.

   

• Disadvantages: YesProximity effect, it is easy to have tone rendering.

Directional Microphone Type 4: Supercardioid Microphone

• Sound sensitivity: Similar to a cardioid microphone, but the sound pickup range is more focused and less susceptible to interference from side noise.

   

• Applicable scenarios: When you need to record specific sounds and don't want to be disturbed by side noise, such as when recording live performances.

   

• Advantages: Little sound interference from the left and right sides, and high quality unilateral sound reception.

   

• Disadvantages: The sound behind the microphone can be slightly picked up, so be careful of interference from noise behind.

Directional Microphone Type 5: Shotgun Microphone

• Sound sensitivity: The directionality is the narrowest and is least susceptible to interference from noise and ambient sound.

   

• Applicable scenarios: Movies, outdoor programs, etc. require the elimination of sound interference, and the microphone cannot appear on the screen.

   

• Advantages: Accurate radio range and almost no noise interference.

   

• Disadvantages: Handheld radio needs to be aimed at the sound source, otherwise it is easy to have radio deviation.
