When it comes to microphones, understanding the different types of polar patterns is crucial for achieving high-quality sound recordings. Two of the most commonly used polar patterns are supercardioid and hypercardioid. While they may seem similar, there are distinct differences between them that can significantly impact the sound quality of your recordings. In this article, we will delve into the world of microphone polar patterns, exploring the characteristics of supercardioid and hypercardioid microphones, and helping you decide which one is best suited for your specific needs.
Introduction to Microphone Polar Patterns
Microphone polar patterns refer to the way a microphone picks up sound from different directions. The polar pattern of a microphone is a graphical representation of its sensitivity to sound waves arriving from various angles. The most common polar patterns are omnidirectional, cardioid, supercardioid, and hypercardioid. Each pattern has its unique characteristics, advantages, and disadvantages. Understanding the different polar patterns is essential for selecting the right microphone for your application, whether it’s for live performances, studio recordings, or public speaking events.
Cardioid Polar Pattern
Before diving into supercardioid and hypercardioid microphones, it’s essential to understand the cardioid polar pattern. The cardioid pattern is heart-shaped, with the microphone being most sensitive to sound waves arriving from the front and least sensitive to sound waves arriving from the rear. The cardioid pattern is widely used in microphones due to its ability to reject background noise and focus on the sound source. However, the cardioid pattern is not as directional as supercardioid and hypercardioid patterns, which can be beneficial in certain situations.
Supercardioid Polar Pattern
The supercardioid polar pattern is a more directional version of the cardioid pattern. Supercardioid microphones are designed to reject sound waves from the sides and rear, while maintaining a high level of sensitivity to sound waves arriving from the front. The supercardioid pattern is often used in live sound applications, such as concerts and public speaking events, where it’s essential to isolate the sound source from background noise. Supercardioid microphones are also commonly used in film and television production, where they help to capture high-quality dialogue while rejecting ambient noise.
Hypercardioid Polar Pattern
The hypercardioid polar pattern is even more directional than the supercardioid pattern. Hypercardioid microphones are designed to reject sound waves from the sides and rear, while maintaining an extremely high level of sensitivity to sound waves arriving from the front. The hypercardioid pattern is often used in applications where it’s essential to isolate the sound source from background noise, such as in studio recordings, live performances, and public speaking events. Hypercardioid microphones are also commonly used in situations where the sound source is distant from the microphone, such as in film and television production.
Key Differences Between Supercardioid and Hypercardioid Microphones
While both supercardioid and hypercardioid microphones are designed to reject background noise and focus on the sound source, there are some key differences between them. The main difference lies in their directionality and sensitivity to sound waves. Supercardioid microphones are less directional than hypercardioid microphones, which means they are more forgiving when it comes to microphone placement. Hypercardioid microphones, on the other hand, are more directional, which requires more precise microphone placement to achieve optimal sound quality.
Directionality and Sensitivity
The directionality of a microphone refers to its ability to reject sound waves from the sides and rear. Hypercardioid microphones are more directional than supercardioid microphones, which means they are better at rejecting background noise and focusing on the sound source. However, this increased directionality also means that hypercardioid microphones are more sensitive to microphone placement and can be more prone to feedback and distortion.
Microphone Placement and Technique
The placement and technique used with supercardioid and hypercardioid microphones can significantly impact the sound quality of your recordings. Supercardioid microphones are more forgiving when it comes to microphone placement, which makes them easier to use in live sound applications. Hypercardioid microphones, on the other hand, require more precise microphone placement to achieve optimal sound quality. This can be challenging in live sound applications, where the sound source may be moving or the microphone may be subject to vibrations and handling noise.
Applications and Uses
Supercardioid and hypercardioid microphones are used in a variety of applications, including live sound, studio recordings, film and television production, and public speaking events. The choice between a supercardioid and hypercardioid microphone ultimately depends on the specific needs of your application. If you need a microphone that is easy to use and can handle a variety of sound sources, a supercardioid microphone may be the best choice. If you need a microphone that can provide extremely high-quality sound and reject background noise, a hypercardioid microphone may be the better option.
Live Sound Applications
In live sound applications, supercardioid microphones are often preferred due to their ease of use and ability to handle a variety of sound sources. Supercardioid microphones are well-suited for live performances, public speaking events, and conferences, where the sound source may be moving or the microphone may be subject to vibrations and handling noise. Hypercardioid microphones can also be used in live sound applications, but they require more precise microphone placement and can be more prone to feedback and distortion.
Studio Recordings and Film Production
In studio recordings and film production, hypercardioid microphones are often preferred due to their ability to provide extremely high-quality sound and reject background noise. Hypercardioid microphones are well-suited for capturing dialogue, vocals, and instruments in studio recordings and film production, where the sound source is often stationary and the microphone can be precisely placed. Supercardioid microphones can also be used in studio recordings and film production, but they may not provide the same level of sound quality as hypercardioid microphones.
Conclusion
In conclusion, the difference between supercardioid and hypercardioid microphones lies in their directionality and sensitivity to sound waves. Supercardioid microphones are less directional and more forgiving when it comes to microphone placement, while hypercardioid microphones are more directional and require more precise microphone placement to achieve optimal sound quality. The choice between a supercardioid and hypercardioid microphone ultimately depends on the specific needs of your application.

What is the main difference between supercardioid and hypercardioid microphone polar patterns?
The main difference between supercardioid and hypercardioid microphone polar patterns lies in their pickup patterns and sensitivity to sound sources. Supercardioid microphones have a narrower pickup pattern than cardioid microphones, with a tighter area of sensitivity in front of the microphone and a smaller area of rejection at the rear. This makes them more suitable for capturing sound sources in noisy environments, such as live performances or public speaking events. In contrast, hypercardioid microphones have an even narrower pickup pattern than supercardioid microphones, with a more focused area of sensitivity and a larger area of rejection.
The difference in pickup patterns between supercardioid and hypercardioid microphones also affects their sensitivity to sound sources. Supercardioid microphones are more sensitive to sound sources directly in front of the microphone, but less sensitive to sound sources at the sides and rear. Hypercardioid microphones, on the other hand, are highly sensitive to sound sources directly in front of the microphone, but highly resistant to sound sources at the sides and rear. This makes hypercardioid microphones more suitable for applications where a high level of isolation is required, such as in film and television production or live theater performances.
How do supercardioid and hypercardioid microphones handle background noise and bleed?
Supercardioid and hypercardioid microphones are both designed to reject background noise and bleed, but they do so in different ways. Supercardioid microphones use a combination of acoustic and electronic techniques to reject sound sources at the sides and rear, while hypercardioid microphones use a more aggressive rejection pattern to minimize bleed and background noise. This makes hypercardioid microphones more suitable for applications where a high level of isolation is required, such as in recording studios or live performances where multiple sound sources are present.
In practice, supercardioid microphones are often used in situations where some bleed is acceptable, such as in live performances or public speaking events. Hypercardioid microphones, on the other hand, are often used in situations where a high level of isolation is required, such as in film and television production or live theater performances. By choosing the right microphone polar pattern for the application, sound engineers and technicians can minimize background noise and bleed, and capture high-quality sound with greater accuracy and precision.

How do supercardioid and hypercardioid microphones compare to other microphone polar patterns?
Supercardioid and hypercardioid microphones are both types of unidirectional microphones, which means they are designed to capture sound sources from a specific direction while rejecting sound sources from other directions. They are often compared to other unidirectional microphones, such as cardioid and shotgun microphones, which have different pickup patterns and rejection characteristics. Supercardioid microphones are generally more sensitive than cardioid microphones, but less sensitive than hypercardioid microphones. Hypercardioid microphones, on the other hand, are highly sensitive and have a very narrow pickup pattern, making them well-suited for applications where a high level of isolation is required.
In comparison to other microphone polar patterns, supercardioid and hypercardioid microphones offer a unique combination of sensitivity and rejection. They are more sensitive than omnidirectional microphones, but less sensitive than bidirectional microphones. They are also more resistant to background noise and bleed than cardioid microphones, but less resistant than shotgun microphones. By choosing the right microphone polar pattern for the application, sound engineers and technicians can capture high-quality sound with greater accuracy and precision, and minimize background noise and bleed.
What are the key considerations when choosing between supercardioid and hypercardioid microphones?
When choosing between supercardioid and hypercardioid microphones, there are several key considerations to keep in mind. First, consider the application and the type of sound source being captured. Supercardioid microphones are well-suited for live performances and public speaking events, while hypercardioid microphones are better suited for film and television production, live theater performances, and recording studios. Second, consider the level of isolation required, as hypercardioid microphones provide a higher level of rejection than supercardioid microphones. Finally, consider the sound quality and tone required, as supercardioid and hypercardioid microphones can produce different tonal characteristics.
In addition to these considerations, it’s also important to think about the microphone’s frequency response, sensitivity, and self-noise. Supercardioid and hypercardioid microphones can have different frequency responses, with some microphones emphasizing certain frequency ranges over others. They can also have different sensitivity levels, with some microphones being more sensitive than others. By considering these factors and choosing the right microphone for the application, sound engineers and technicians can capture high-quality sound with greater accuracy and precision, and minimize background noise and bleed.
How can I optimize the performance of my supercardioid or hypercardioid microphone?
To optimize the performance of your supercardioid or hypercardioid microphone, there are several steps you can take. First, make sure the microphone is positioned correctly, with the sound source directly in front of the microphone and the microphone angled to minimize bleed and background noise. Second, adjust the microphone’s gain and EQ settings to optimize the sound quality and tone. Third, use acoustic treatment and soundproofing to minimize reflections and reverberation, which can affect the microphone’s performance. Finally, consider using a windscreen or pop filter to reduce plosive sounds and minimize distortion.
In addition to these steps, it’s also important to consider the microphone’s polar pattern and how it interacts with the sound source and environment. Supercardioid and hypercardioid microphones can be sensitive to sound reflections and reverberation, so it’s important to position the microphone carefully and use acoustic treatment and soundproofing to minimize these effects. By optimizing the performance of your supercardioid or hypercardioid microphone, you can capture high-quality sound with greater accuracy and precision, and minimize background noise and bleed. Regular maintenance and calibration of the microphone can also help to ensure optimal performance and extend its lifespan.
