Transcript

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