F3:The roll-off frequency at which the driver's response is down -3dB from the level of it's midband response. 2. F3 (measured in Hz) 3. Fader-Rather like the right to left balance control, however the fader moves the sonic position between the front and back speakers. 4. Fader 5. Fader:The control that varies the amplitude of the front vs. rear sound. (e.g., When Susan moved the fader to full rear, the front speakers could no longer be heard.) 6. Farad:-The basic unit of capacitance. A capacitor has a value of one farad when it can store one coulomb of charge with one volt across it. 7. Farad (F):-The basic unit of capacitance. A capacitor has a capacitance of 1F when a charge of 1 Volt across the capacitor produces a current of 1 Ampere through it. Named after Michael Faraday. 8. Fb:The tuned frequency of a Vented Enclosure, measured in Hertz. A combination of the resonance frequency of the air in a Port and the resilient pressure of the air in a Ported System. Below this point the Frequency Response of a Tuned Port system rapidly Falls Off, and the system can become unstable if asked to reproduce lower frequencies at high Amplitude. 9. Fb:The tuned frequency of a ported box. 10. Fc or Fcb: 11. FFT (Fast-Fourier Transform):A method by which a system is described using an impulse response. Both frequency and time data can be extracted, with room reflections removed, providing an extremely accurate analysis. Mathematical manipulation of the data is employed to view system parameters from a variety of perspectives. 12. Fidelity-A term used to describe the accuracy of recording, reproduction, or general quality of audio processing. Getting it "high" is every designer's goal 13. Filter 14. Filter:An electrical circuit or mechanical device that removes or attenuates energy at certain frequencies. . An electrical circuit or mechanical device that removes or attenuates energy at certain frequencies. . 15. Flat:-A response that is relatively linear from the lowest to the highest audible frequencies. (e.g., Most installers will use an equalizer to get a flat response in cars.) 16. Flat: 17. Flat Response:The faithful reproduction of an audio signal; specifically, the variations in output level of less than 1 dB above or below a median level over the audio spectrum. 18. Flat Response:-An output signal in which fundamental frequencies and harmonics are in the same proportion as those of the input signal being amplified. A flat frequency response would exhibit relatively equal response to all fixed-point frequencies within a given spectrum. 19. Fletcher-Munson curve-Our sensitivity to sound depends on its frequency and volume. Human ears are most sensitive to sounds in the midrange. At lower volume levels humans are less sensitive to sounds away from the midrange, bass and treble sounds "seem" reduced in intensity at lower listening levels. 20. Fletcher-Munson Curves 21. Flush (mounting):Mounting a speaker in such a way that the speaker and its Grill do not protrude above the surrounding surface. Usually, this means mounting it at the back of the baffle board (the board the speaker is mounted on). 22. Flux-The flow of magnetic energy in a circuit. Flux density is the measure of the strength of the magnetic field typicaly used in speakers, and which governs its power handling capacity. 23. Former:-The cylindrical portion of a speaker's voice coil section. A wire is wound around this cylinder to form a coil such that when current interacts with the magnetic field it produces a pumping motion that alternatively compresses and rarifies air, and creates the velocity for such air masses to reach our ears as sound. 24. Free Air Resonance 25. Free sound field 26. Free-Air Configuration:This description usually indicates a speaker that, in the opinion of the manufacturer, is suitable for mounting in only a minimal enclosure, such as a baffle board that separates the back wave from the front. 27. Frequency:1. The property or condition of occurring at frequent intervals. 2. Mathematics. Physics. The number of times a specified phenomenon occurs within a specified interval. In sound this simply refgers to the regular occurence of compression and rarification of air that we experience as sound. 28. Frequency-Simply the number of events or cycles that occur in a time period, usually one second. Frequency is measured in Hertz (Hz), which are the number of cycles per second. (e.g., Humans can experience sound from 20 Hz to over 20,000 Hz.) 29. Frequency 30. Frequency 31. Frequency Modulation (FM): 32. Frequency Response-The range of frequencies that a speaker will reproduce (lowest frequency to the highest). While the optimal normal is 20 - 20,000 Hz (Hertz), the range of human hearing for individuals is often much more restricted. A good full-range speaker system however, will reproduce as much of this range as possible in order to cover all variations. Individual Drivers are limited to reproducing only that part of the spectrum for which they were made, so their response will be limited, but still a necessary point to consider when designing a complete sound system. 33. Frequency Response 34. Frequency Response:-How well a circuit or system transmits the frequencies that are applied to it. (e.g., The frequency response of my new amplifier was virtually flat from 20 Hz up to 20,000 Hz.) 35. Fs 36. Fs: 37. Full Logic Deck 38. Full Range-Containing or able to handle all the frequencies normally experienced by us humans (from 20 Hz up to 20,000 Hz). (e.g., A full range speaker is one that was designed as the only speaker in a system.) 39. Full Range-Containing or able to handle all the frequencies normally experienced by us humans (from 20 Hz up to 20,000 Hz). (e.g., A full range speaker is one that was designed as the only speaker in a system.) 40. Full-range 41. Fundamental 42. Fuse:A simple device that limits the current flowing in a circuit and therefore protects the alternator, battery, electrical wiring, and the components. The current flow is disrupted when the fuse element melts and opens the circuit. (e.g., For safety, a component installer will always add a fuse very near the positive battery post.) 43. Fuse:A simple device that limits the current flowing in a circuit and therefore protects the alternator, battery, electrical wiring, and the components. The current flow is disrupted when the fuse element melts and opens the circuit. (e.g., For safety, a component installer will always add a fuse very near the positive battery post.) 44. Fuse 45. Fusible Link:-Designed to perform the same task as a fuse, but the resembles a wire. Fusible links are commonly used in power transformers, ignition switches and other high current circuits. |
