Monkeys experience octave equivalence, and its biological basis apparently is an octave mapping of neurons in the auditory thalamus of the mammalian brain. [12] Studies have also shown the perception of octave equivalence in rats, [13] human infants, [14] and musicians [15] but not starlings, [16] 4–9-year-old children, [17] or non-musicians.

For example, the frequency one octave above 40 Hz is 80 Hz. The term is derived from the Western musical scale where an octave is a doubling in frequency.
