Summary

I worked with a group to record three different sounds while taking pictures of the sound sources.

Audio Terms and Definitions

  • Sound Wave
    • A vibrational disturbance that involves the mechanical motion of molecules transmitting energy from one place to another.
  • Compression
    • Reducing a signal’s output level in relation to its input level to reduce dynamic range.
  • Frequency
    • The # of times per second that a sound source vibrates, is expressed in hertz (Hz).
  • Hertz
    • Unit of measurement of frequency; numerically equal to cycles per second (cps).
  • Infrasonic
    • The range below the frequencies is audible to human hearing.
  • Ultrasonic
    • The range above the frequencies of human hearing.
  • Pitch
    • The subjective perception of frequency – the highness or lowness of a sound.
  • Fundamental
    • The lowest frequency a 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.
  • Sound Frequency Spectrum
    • The range of frequencies audible to human hearing: about 20 to 20,000 Hz.
  • Octave
    • The interval between the two frequencies that have a tonal ratio of 2:1.
  • Bass
    • The low range of the audible frequency spectrum; is usually from 20 to 320 Hz.
  • Midrange
    • The part of the frequency spectrum to which humans are most sensitive; is the frequencies between roughly 320 Hz and 2,560 Hz.
  • Treble
    • The frequency range between roughly 5,120 Hz and 20,000 Hz, the highest two octaves audible to human hearing in the sound frequency spectrum.
  • Equalization
    • A signal-processing device that can boost, attenuate, or shelve frequencies in a sound source or sound system.
  • Amplitude
    • The magnitude of a sound wave or an electric signal is measured in decibels.
  • Decibel (dB)
    • A relative and dimensionless unit to measure the ratio of two quantities.
  • Wavelength
    • Distance between two peaks of a wave
  • Velocity
    • Speed in a given direction
  • Harmonic
    • Is a multiple of the fundamental frequency
  • Phase
    • Factor in the interaction of one wave with another, either acoustically or electronically
