Properties of Sound

This control affects how a sound changes over time (sudden, slowly, fading).

• Duration

• Oscillator

• Envelope

• Hertz

The term for something that cycles back and forth (math function, pendulum, electronic circuit).

• Balance

• Generation

• Structure

• Oscillator

This frequency is the note A4 above Middle C.

• 440 Hz.

• 20hz to 20khz

• 880 kHz.

• 220.

These instruments produce sound using vibrating air (flute, horn, accordion).

• Chordophones

• Electrophones

• Ideophones

• Aerophones

The range of human hearing is appoximately

• 20khz to 20mhz

• 20 to 20 hz

• 20hz to 20khz

• 20mhz to 20khz

This is the unit of measure of frequency. For example, 1_____ equals 1 cycle per second, 1 kilo_____ equals 1000 cycles per second.

• Hertz

• Spectrum

• Amplitude

• Frequency

These controls can amplify (boost, turn up), pass, or attenuate (cut, turn down) some frequency ranges to affect timbre.

• Amplifiers

• Envelopes

• Waveforms

• Filters
