The Shure SM58 is one of the most iconic and widely used microphones in the music industry, known for its durability, versatility, and exceptional sound quality. However, there’s a common misconception about its polar pattern, with many users wondering if the SM58 is omnidirectional. In this article, we’ll delve into the world of microphone polar patterns, explore the characteristics of the SM58, and provide a clear answer to this question.
Understanding Microphone Polar Patterns
Before we dive into the specifics of the SM58, it’s essential to understand the different types of microphone polar patterns. A polar pattern refers to the way a microphone picks up sound from various directions. The three primary polar patterns are:
Cardioid, Omnidirectional, and Figure-Eight Patterns
- Cardioid microphones are designed to pick up sound from the front and reject sound from the rear, making them ideal for live performances and public speaking.
- Omnidirectional microphones, on the other hand, pick up sound from all directions, including the front, rear, and sides. This type of microphone is often used for recording ambient sound or capturing a wide soundstage.
- Figure-Eight microphones, also known as bidirectional microphones, pick up sound from the front and rear, while rejecting sound from the sides.
Polar Pattern and Its Impact on Sound Quality
The polar pattern of a microphone plays a significant role in determining its sound quality and suitability for various applications. For instance, a cardioid microphone like the SM58 is less prone to feedback and can help reduce ambient noise, making it an excellent choice for live performances. On the other hand, an omnidirectional microphone can capture a more immersive soundstage, but may also pick up unwanted background noise.
The SM58: A Closer Look
Now that we’ve covered the basics of microphone polar patterns, let’s take a closer look at the SM58. The Shure SM58 is a dynamic microphone that’s been a staple in the music industry for decades. Its rugged design, high-quality sound, and affordability have made it a favorite among musicians, sound engineers, and public speakers.
SM58 Polar Pattern: The Truth Revealed
So, is the SM58 omnidirectional? The answer is no. The SM58 has a unidirectional cardioid polar pattern, which means it’s designed to pick up sound from the front and reject sound from the rear. This polar pattern makes the SM58 an excellent choice for live performances, public speaking, and recording applications where a focused sound is desired.
SM58 Frequency Response and Proximity Effect
The SM58 has a frequency response of 50 Hz to 15 kHz, which is well-suited for capturing the human voice and a wide range of instruments. Additionally, the SM58 exhibits a proximity effect, which means that the bass response increases as the microphone is moved closer to the sound source. This effect can be both beneficial and detrimental, depending on the application. For instance, the proximity effect can add warmth and depth to a vocal performance, but can also introduce unwanted low-end rumble if not used carefully.
Real-World Applications of the SM58
The SM58 is an incredibly versatile microphone that’s been used in a wide range of applications, from live performances and public speaking to recording and broadcasting.
Live Performances and Public Speaking
The SM58 is a popular choice for live performances and public speaking due to its cardioid polar pattern, which helps to reject feedback and ambient noise. Its rugged design and high-quality sound make it an excellent choice for touring musicians, public speakers, and event organizers.
Recording Applications
The SM58 is also widely used in recording applications, particularly for capturing vocals and instruments. Its cardioid polar pattern and proximity effect make it an excellent choice for recording applications where a focused sound is desired. Additionally, the SM58 is often used as a room microphone to capture the ambiance of a recording space.
Conclusion
In conclusion, the SM58 is not an omnidirectional microphone. Its unidirectional cardioid polar pattern makes it an excellent choice for live performances, public speaking, and recording applications where a focused sound is desired. The SM58’s rugged design, high-quality sound, and affordability have made it a staple in the music industry, and its versatility has led to its widespread use in a variety of applications. Whether you’re a musician, sound engineer, or public speaker, the SM58 is an excellent choice for anyone looking for a high-quality, reliable microphone.

What is the difference between omnidirectional and cardioid microphones?
Omnidirectional microphones are designed to pick up sound from all directions, capturing a wide range of frequencies and ambient noise. They are often used in applications where a natural, immersive sound is desired, such as in film and television production, live recordings, and ambient music recordings. In contrast, cardioid microphones, like the SM58, are designed to pick up sound from the front while rejecting sound from the rear, providing a more focused and directional sound.
The main advantage of cardioid microphones is their ability to reduce background noise and feedback, making them ideal for live performances and public speaking applications. Omnidirectional microphones, on the other hand, can capture a more natural and immersive sound, but may require additional processing and noise reduction techniques to minimize ambient noise and feedback. Understanding the differences between omnidirectional and cardioid microphones is essential for selecting the right microphone for a specific application and achieving the desired sound quality.
Is the SM58 microphone truly omnidirectional?
The SM58 microphone is not truly omnidirectional, but rather a unidirectional microphone with a cardioid polar pattern. This means that it is designed to pick up sound from the front while rejecting sound from the rear, providing a more focused and directional sound. While the SM58 does have some pickup from the sides, its cardioid pattern is designed to minimize ambient noise and feedback, making it ideal for live performances and public speaking applications.
The cardioid pattern of the SM58 microphone is achieved through its unique design and construction, which includes a dynamic coil and magnet assembly, a diaphragm, and a grille. The combination of these components allows the SM58 to produce a clear and crisp sound while rejecting ambient noise and feedback. While some microphones may have a more omnidirectional pattern, the SM58’s cardioid pattern is a key factor in its popularity and widespread use in the audio industry.
What are the benefits of using a cardioid microphone like the SM58?
