11. Octave
a. In audio, an octave is the interval between
any two frequencies having a ratio of 2 to 1.
Example: 100 Hz and 200 Hz are an
octave apart.
b. In music, an octave is the interval of eight
diatonic degrees between two tones, one of
which has twice as many vibrations per
second as the other.
Example A1 and A2 on
a piano are an octave apart. Although similar
to audio, some instruments are not exactly
two times the frequency due to what’s know
as stretched temperament. In equal
temperament, the ratio of frequencies in a
semitone is the twelfth root of two (
12
√
2).
Every interval is then simply a certain
number of semitones. Only the octave
(the twelfth power of the twelfth root) is
a pure interval.
12. Haas Effect: Also called the precedence effect,
describes the human psycho-acoustic phenom-
ena of correctly identifying the direction of a
sound source heard in both ears but arriving at
different times. Due to the head's geometry the
direct sound from any source first enters the
ear closest to the source, then the ear farthest
away. The Haas Effect tells us that humans
localize a sound source based upon the first
arriving sound if the subsequent arrivals are
within 25-35 milliseconds. The Haas Effect is
named after Helmut Haas, a distant relative of
Scott Haas.
