Shure’s SM58 and SM57 are iconic dynamic microphones known for their exceptional sound quality, durability, and versatility. While these two microphones share some similarities, they are designed with distinct purposes in mind. In this article, we’ll explore the differences in specs and applications between the Shure SM58 and SM57 to help you make an informed choice when selecting the right microphone for your needs.
Basic Similarities
Before diving into the differences, it’s essential to acknowledge the fundamental similarities between the SM58 and SM57:
- Transducer Type: Both microphones are dynamic, meaning they use electromagnetic induction to convert sound waves into electrical signals.
- Polar Pattern: Both have a cardioid polar pattern, which means they are most sensitive to sound from the front while rejecting sound from the sides and rear.
- Durability: Both microphones are built to withstand rigorous use and are renowned for their rugged construction.
Differences in Specs and Applications
- Frequency Response:
- SM58: The SM58 has a frequency response of 50Hz to 15kHz. Its tailored frequency response emphasizes vocals, making it a go-to choice for live vocals and spoken word applications.
- SM57: The SM57 has a slightly wider frequency response of 40Hz to 15kHz. This broader range makes it suitable for a variety of instruments and sound sources.
- Applications:
- SM58: The SM58 is primarily designed for vocal applications. Its built-in spherical wind and pop filter helps reduce plosive sounds and breath noise, making it ideal for singing and spoken word.
- SM57: The SM57 is a versatile workhorse known for its instrumental miking capabilities. It excels at capturing the sound of instruments such as guitar amplifiers, snare drums, toms, and brass instruments.
- Grille and Windscreen:
- SM58: The SM58 has a built-in grille and windscreen that are specifically designed for vocal use. The grille helps with reducing plosives and wind noise during close vocal miking.
- SM57: The SM57 features a more open grille design, which allows it to capture instruments with greater accuracy. It does not have a built-in windscreen like the SM58.
- Grille Shape:
- SM58: The SM58 has a spherical grille, which is intended to help prevent artists from “eating” the microphone while performing, thus maintaining consistent sound quality.
- SM57: The SM57 has a flatter grille shape that provides better proximity to sound sources like guitar amplifiers and drums.
- Popularity:
- SM58: The SM58 is often considered the industry standard for live vocal miking and is one of the most popular microphones for this purpose.
- SM57: The SM57 is renowned for its versatility and is frequently used in both live sound and studio recording, particularly for instrument miking.
Conclusion
While the Shure SM58 and SM57 share some core characteristics, their distinct frequency responses, applications, and grille designs set them apart. The SM58 is tailored for vocal performance and spoken word applications, while the SM57’s versatility shines when capturing the sound of various instruments. Choosing between them ultimately depends on your specific audio needs and whether you prioritize vocal or instrumental recording and reinforcement. Both microphones represent the high-quality and reliable standards that Shure is known for in the audio industry.
