- 2. Soundwave A vibrational disturbancethat involves mechanical motion of molecules transmitting energy from one place to another.
- 3. Wavelength The distance betweentwo peaks of a wave.
- 4. Compression Reducing a signal’soutput level in relation to its input level to reduce dynamic range.
- 5. Frequency The number oftimes per second that a sound source vibrates, expressed in hertz(Hz).
- 6. Hertz Unit of measurementof frequency; numerically equal to cycles per second(cps).
- 7. Pitch The subjective perceptionof frequency - the highness or lowness of a sound.
- 8. Amplitude The magnitude ofa sound wave or an electric signal measured in decibels(dB).
- 9. Decibel A relative anddimensional unit to measure the ratio of two quantities.
- 10. Sound Frequency Spectrum Therange of frequencies audible to human hearing: about 20 to 20,000 Hz
- 11. Infrasonic The range belowthe frequencies audible to human hearing.
- 12. Ultrasonic The range abovefrequencies of human hearing.
- 13. Midrange The part ofthe frequency spectrum to which humans are most sensitive; the frequencies between roughly 320 Hz and 2,560 Hz.
- 14. Bass The low rangeof the audible frequency spectrum; usually from 20 to 320 Hz.
- 15. Treble Frequency range betweenroughly 5,120 Hz and 20,000 Hz, the highest two octaves audible to human hearing in the sound frequency spectrum.
- 16. Fundamental The lowest frequencya sound source can produce. In other words, it is also called the first harmonic or primary frequency which is the lowest, or basic, pitch of a musical instrument.
- 17. Phase Factor in theinteraction of one wave with another, either acoustically or electronically.
- 18. Velocity Speed in agiven direction.
- 19. Octave The interval betweentwo frequencies that have a tonal ratio of 2:1.
- 20. Harmonic A multiple ofthe fundamental frequency. A wave with a frequency that is a positive integer multiple of the frequency of the original wave.
- 21. Equalization A signal-processing devicethat can boost, attenuate, or shelve frequencies in a sound source or sound system.
