SM7B vs SM58: Technical Specifications

Diving into the technicalities, both microphones have unique specifications that cater to different needs and applications.

Frequency Response

The SM7B offers a flat, wide-range frequency response, making it ideal for capturing both vocals and instruments with precision. Its response can be adjusted with the presence boost and high-pass filter switches. The SM58, tailored for vocals, has a tailored frequency response with a brightened midrange and bass roll-off. This ensures vocals stand out in the mix, especially in live settings.

  • How Frequency Response Affects Sound: Frequency response plays a pivotal role in how a microphone captures sound. A flat response, like that of the SM7B, ensures all frequencies are represented equally, providing a natural sound. A tailored response, as in the SM58, emphasizes certain frequencies, enhancing specific sound characteristics.
  • Comparison of SM7B and SM58 Frequency Curves: While both mics come from the same family, their frequency curves differ. The SM7B’s flat curve is versatile, while the SM58’s midrange boost is perfect for making vocals pop in live mixes.

Sensitivity And SPL Handling

The SM7B, being a studio microphone, has a lower sensitivity, making it perfect for close-miking applications. It can handle high sound pressure levels (SPL) without distortion, suitable for loud instruments or vocalists.

The SM58, designed for live vocals, has a higher sensitivity. Its dynamic nature allows it to handle loud sound sources with ease, making it a favorite among rock vocalists.

  • Importance of Sensitivity in Microphones: Sensitivity determines how well a microphone converts acoustic energy into electrical energy. A mic with high sensitivity will produce a stronger output signal at a given sound pressure level.
  • How Both Mics Handle Loud Sound Sources: Both SM7B and SM58 excel in handling loud sources. The SM7B’s design ensures minimal distortion, even with loud instruments. The SM58, with its dynamic mic nature, can withstand high SPLs, making it ideal for live performances. This makes choosing the right audio interface even more important, as some interfaces may require more gain to drive these microphones effectively.

Polar Patterns

The SM7B features a cardioid polar pattern, perfect for isolating sound sources in a studio setting. The SM58, also cardioid, excels in rejecting off-axis sounds, ensuring clear vocals on stage. But which mic is better for isolating sound?

Both mics, with their cardioid patterns, are adept at isolating sound. However, the SM7B, with its larger diaphragm and studio design, might have a slight edge in sound isolation in controlled environments.
