Dynamic microphone

Definition

A dynamic microphone is a type of microphone that uses a moving coil to convert sound waves into electrical signals. These microphones are known for their durability, ability to handle high sound pressure levels, and excellent performance in live sound situations. Their design makes them ideal for a variety of applications, including studio recording, field interviews, and voiceover work, as they can capture sound with clarity while minimizing background noise.

5 Must Know Facts For Your Next Test

1. Dynamic microphones are typically less sensitive than condenser microphones, making them great for live performances where high sound levels are present.
2. They are often used for capturing vocals and instruments on stage due to their rugged construction and ability to reject background noise.
3. Dynamic microphones do not require an external power source, which makes them easy to use in various settings without worrying about batteries or phantom power.
4. The frequency response of dynamic microphones tends to be less flat compared to condenser microphones, but they excel at handling loud sounds without distortion.
5. Common examples of dynamic microphones include the Shure SM58, widely used for vocal performances, and the Shure SM57, popular for instrument recording.

Review Questions

• How does a dynamic microphone differ from other types of microphones in terms of sensitivity and application?
  • Dynamic microphones are generally less sensitive than condenser microphones, making them better suited for live sound environments where higher sound pressure levels are present. Their durability allows them to withstand rough handling during performances, which is not always the case with more sensitive types. As a result, dynamic microphones are often the go-to choice for capturing loud sounds like drums or electric guitar amplifiers.
• Discuss the advantages of using dynamic microphones in voiceover recording compared to other types of microphones.
  • Dynamic microphones offer several advantages in voiceover recording, including their ability to reject unwanted background noise and their resilience against plosive sounds. This makes them suitable for recording in less-than-ideal environments where ambient noise may be an issue. Additionally, since they don’t require phantom power, they can be easily connected to various recording devices without needing additional equipment.
• Evaluate the role of dynamic microphones in different audio recording techniques and their impact on overall sound quality.
  • Dynamic microphones play a crucial role in various audio recording techniques by providing robust performance in high-SPL situations without distortion. Their design allows them to capture a specific sound source clearly while minimizing interference from surrounding noise. In studio environments, they can complement other microphone types by adding warmth and character to recordings. Their versatility across applications—from live settings to voiceovers—highlights their significance in achieving high-quality audio capture.
