Microphones Microphones Presentation Transcript

  • Microphones By Jonothan Hall Stefan Rutherford Tom Bellingham
  • Introduction
    • Shure Sm57 £70
    • Sennheiser E604 £110
    • AKG D112 £120
  • Health & Safety
    • Trailing wires
    • Excessive Noise levels
    • Pat tested equipment
  • General Design
    • Rugged construction for all three
    • All handle high SPL’s
    • Designed for specific uses
    • Don’t require external power (+48 etc)
  • How They Work?
    • Sound waves hit microphone diaphragm
    • Diaphragm vibrates
    • Coil attached to diaphragm also vibrates
    • Magnet creates a magnetic field
    • Coil moves back and forth
    • Magnetic field changes, creating alternating current
  • Polar Patterns Omni directional Sub cardioid Super cardioid Hyper cardioid Figure of 8 Shotgun Cardioid
  • Polar Patterns
    • Picks up front
    • Rejects behind
  • Audio Performance
    • Pink Noise played through speaker
    • View microphones frequency response
    • Use Analyser in logic pro
  • Audio Performance
    • Flat Response mic
    • Shure Sm57
  • Audio Performance
    • Flat Response Mic
    • Sennheiser E604
    • AKG D112
  • Specifications
    • Shure Sm57
    • Sennheiser E604
  • Specifications
    • AKG D112
  • Microphone Applications
    • Shure Sm57 designed for: Live sound Guitar amps Snare drums
    • Sennheiser E604 designed for: Live sound Toms
    • AKG D112 designed for: Live sound Bass drum Bass amps
  • Evaluation
    • The equipment was not ideal
    • Could have tested condenser microphones
    • Couldn’t test dynamic range (equipment breakage)
    • Polar patterns could have been tested more in depth (different types tested from more directions at different frequencies)
    • Sine wave sweep may be more accurate than noise for testing frequency response
