Bibliography14 Introduction You wouldn't think a loudspeaker and a car engine have a lot in common, would you? Well perhaps not a lot but they definitely share one important thing – both have seen almost no change to their fundamental form in decades. Of course technological progress has supplied them with more sophisticated materials. Hence nowadays they are more efficient than ever before. However, the car still uses a series of small sparks to get from point A to point B and we still use the speaker cone to move air particles. Period. But is it really that simple? Certainly not. Since I have limited knowledge of car engines, I will instead focus on the principles of functionality and design of dynamic moving coil loudspeakers.

The tones in “Neutral Tones” seem to be indifferent, or Neutral. The speaker of…

  • Reverb And Delay Analysis

    sound images fused together to create something new. Using the previous example of an individual shouting the word ‘hello’ into a cave, while the first ‘hello’ received back would be the echo or delay, this quickly and subsequently will turn into a series of hellos as the sounds continue to bounce of the walls and the ceiling.

    “All buggers report to duty immediately! Our defense systems have been breached! All buggers report to duty immediately! Our defense systems have been breached!” blared the loudspeakers repeatedly in my quarters, each message sending an echo down the narrow hallway leading to the other buggers’ quarters.
