  • Supercardioid and hypercardioid mics provide tighter sound isolation, suitable for noisy environments.
  • Selecting the appropriate microphone pattern enhances audio clarity and quality for your specific application.

Basics of Microphones

Microphones are essential tools for capturing sound. You can think of them as translators, turning physical sound waves into electrical signals that can be amplified, recorded, or broadcasted.

There’s a range of microphones available, each suited to specific tasks based on their design, polar patterns, and sensitivity.

Dynamic microphones are known for their durability and ability to handle high sound pressure levels. They’re often your go-to for live performances.

On the other hand, condenser microphones require power, either from a battery or phantom power, and are prized for their sensitivity and broader frequency response. This makes them favorites in studio settings.

When it comes to microphone polar patterns, you’ll find several types:

  • Cardioid: Ideal for picking up sound from the front while rejecting noise from the sides and back.
  • Supercardioid: Similar to cardioid but with a narrower area of sensitivity at the front and a small lobe of pick-up at the rear.
  • Hypercardioid: Offers an even tighter front pick-up than supercardioid and a larger rear lobe.

Here’s a quick reference table:

Polar Patterns Explained

Microphone polar patterns are crucial because they determine how well a mic captures sound from various directions. Understanding these patterns can help you choose the right microphone for your recording situation.

Cardioid Mics

The cardioid polar pattern is heart-shaped, making it sensitive to sound from the front while rejecting noise from the back and sides.

Microphones with this pattern are ideal for scenarios where you need to isolate the sound source, such as live vocals or podcast recording.

Super and Hypercardioid Mics

Supercardioid and hypercardioid mics offer tighter front-directional capture, with supercardioid being less sensitive at 125 degrees and hypercardioid at 110 degrees off-axis.

They’re suitable for loud stages where feedback and background noise rejection is important. Here’s how these mics differ from cardioid mics:

  • Supercardioid:
    • Picks up some sound from the rear
    • Maximum rejection at 125 degrees
  • Hypercardioid:
    • Even less front sensitivity than supercardioid
    • Maximum rejection at 110 degrees
    • Picks up more sound from the rear than supercardioid mics

Omnidirectional Mics

An omnidirectional microphone picks up sound equally from all directions. This makes them versatile for capturing ambient sounds or recording a group of instruments acoustically.

Bidirectional Mics

Also known as the figure-of-eight patternbidirectional microphones capture sound from the front and rear but reject sound from the sides.

These mics are particularly useful for recording two people facing each other, like in an interview setup.

Directionality and Noise Rejection

When selecting a microphone, directionality and noise rejection are critical factors that determine your audio’s clarity and quality.

Let’s break down what these terms mean and how they apply to cardioid, supercardioid, and hypercardioid microphones.

Frequently Asked Questions

When selecting a microphone for specific audio applications, understanding the nuances of different polar patterns is crucial for achieving the best sound capture. These questions will clarify the intricacies of cardioid, supercardioid, and hypercardioid microphones.

What are the differences in the pickup patterns of cardioid, hypercardioid, and supercardioid microphones?

Cardioid microphones are known for their heart-shaped pickup patterns, which are most sensitive to sound from the front and offer a wide angle of acceptance.

In contrast, hypercardioid microphones have a narrower front pickup angle and a smaller lobe of sensitivity at the rear, making them more focused but susceptible to sound directly behind them.

Supercardioid microphones, on the other hand, offer a balance between these two, with a slightly wider front pickup angle than hypercardioid microphones but less rear sensitivity than cardioid mics, providing a tighter front pickup with some rear lobe sensitivity.

In what situations would a supercardioid mic be preferred over a cardioid mic?

You might prefer a supercardioid microphone in live performances or events where sound source isolation is key, such as on a noisy stage.

Its tighter pickup pattern focuses on the sound in front of it while offering better side rejection compared to a cardioid mic, making it great for capturing sounds in a more controlled and directed manner.

Can you explain how the proximity effect varies between cardioid and supercardioid microphones?

The proximity effect causes an increase in bass frequencies when a sound source is close to a microphone. Both cardioid and supercardioid microphones exhibit this effect.

However, cardioid microphones tend to have a more pronounced proximity effect due to their wider front pickup pattern.

Supercardioid microphones can also exhibit a noticeable proximity effect, but it may be slightly less pronounced due to their tighter directional characteristics.

What are the advantages and disadvantages of using a hypercardioid microphone compared to other types?


  • Excellent side rejection, minimizing ambient noise and room reflections.
  • Focused pickup pattern is ideal for miking individual sound sources in a mix.


  • Increased sensitivity to sound directly behind the microphone.
  • Less versatile than cardioid mics in some applications due to its narrow pickup pattern.

How do cardioid, hypercardioid, and supercardioid microphones differ in their sensitivity to sound from different directions?

Cardioid microphones are least sensitive to sound coming from behind, making them great for general use.

Hypercardioid microphones have a tighter front sensitivity with a small lobe picking up some sound from the rear.

Supercardioid mics are a middle ground, with less sensitivity from the rear than a cardioid but more than a hypercardioid and a narrower front pickup pattern.

Why might someone choose a hypercardioid mic over a shotgun microphone?

Hypercardioid microphones are less directional than shotgun microphones. This can be beneficial in environments where sound reinforcement is needed, but where the highly directional nature of a shotgun mic would be too limiting.

They are capable of capturing more natural-sounding audio within a controlled front-facing area. This makes them suitable for settings where some ambient noise is acceptable, but isolation from the sides is desire
