Dynamic Microphone

Definition

A dynamic microphone is a type of microphone that uses a moving coil to convert sound waves into electrical signals. This type of mic is known for its durability, ability to handle high sound pressure levels, and often has a focused pickup pattern, making it ideal for live sound applications and recording instruments.

5 Must Know Facts For Your Next Test

1. Dynamic microphones are typically less sensitive than condenser microphones, making them great for high-volume sources like drums and guitar amplifiers.
2. They are often more durable and can withstand rough handling, which makes them popular for live performances.
3. The moving coil design allows dynamic mics to capture sound without needing external power, making them easy to set up.
4. Frequency response in dynamic microphones is generally less flat than condensers, often emphasizing mid-range frequencies which can add warmth to vocals.
5. Because of their cardioid polar pattern, dynamic microphones effectively reduce background noise and feedback, making them ideal for stage use.

Review Questions

• How does the construction of a dynamic microphone influence its performance in different environments?
  • The construction of a dynamic microphone, which features a moving coil diaphragm, allows it to handle high sound pressure levels without distortion. This makes it particularly effective in loud environments like concerts or live events. Additionally, the robustness of dynamic microphones contributes to their reliability in these settings, ensuring they can withstand the physical demands of frequent transportation and use.
• Discuss the advantages of using dynamic microphones over condenser microphones when tracking certain instruments.
  • Dynamic microphones have distinct advantages when tracking certain instruments due to their ability to handle high sound pressure levels without distortion. For example, when recording electric guitar amplifiers or drums, dynamic mics excel at capturing the punch and energy of the performance. Additionally, their directional pickup pattern helps isolate the instrument from ambient noise, making them more effective in live or uncontrolled environments.
• Evaluate how the frequency response and sensitivity of dynamic microphones impact their application in studio versus live settings.
  • Dynamic microphones generally have a limited frequency response compared to condenser microphones, emphasizing mid-range frequencies while rolling off lows and highs. This characteristic can be beneficial in live settings where feedback control is crucial, but may require additional tonal shaping in studio applications. In studios, while they can be used effectively for certain instruments and vocal styles, producers might opt for condensers for more nuanced recordings due to their wider frequency response and sensitivity.

Related terms

Condenser Microphone: A condenser microphone uses an electrically charged diaphragm and backplate to capture sound, known for its sensitivity and wide frequency response, often used in studio settings.

Polar Pattern:

The polar pattern describes how a microphone picks up sound from different directions, which influences its use in various recording situations, like cardioid or omnidirectional.

Phantom Power:

Phantom power is a method of providing power to condenser microphones via the microphone cable, which dynamic microphones do not require.
