What is sound? - ANS Airborne vibrations that enter the ear and are then translated by the
brain into the sensation known as sound
Cycles - ANS Ripples through the air
Human hearing approx: - ANS 20/50 Hz - 20,000 Hz
What is 20,000 Hz better known as? - ANS 20 kHz
What is the Essence of Sound? - ANS Waveform Pitch
Timbre
Volume
PITCH - ANS Is derived from the fundamental frequency of the sound of "waveform"
Faster the frequency, the higher the "pitch"

, The simplest sound is a ... - ANS Pure tone, which means only a single frequency is present
Sine Wave - ANS Is the purest waveform; it contains only a single frequency
Overtones - ANS Most sounds consist of a single tone plus a series of overtones. These
overtones are called harmonics
Harmonics - ANS Are other frequencies that are exact multiples of the basic or fundamental
pitch
There are even and odd numbered harmonics
Noise - ANS White/Pink/Other colors as well - Has NO single fundamental pitch present
The character or "TIMBRE" of a sound is determined by 2 factors: - ANS Harmonics and Non-
Harmonics that create the sound
The way these components change in both level and pitch as the "Sound Evolves" over time
VOLUME - ANS Amplitude of the wave determines the volume
Higher the amplitude, louder the sound
Lower the amplitude, softer the sound
"Envelope" of Sound - ANS The way pitch and harmonics, and even volume, behave over time
also have an impact on "Pitch," "Timbre," and "Volume"
