| "This sensitivity is exhibited even in newborns indicating that an attunement to organized sound is an evolutionary adaptation in the human species." |
| Cochlear sound is "the perceived sound associated with the kinetic energy vibrations within the cochlea that produce electrochemical signals in the brain." |
| "non-cochlear sounds are perceived sounds associated with the excitation of the auditory cortex in the human brain by means other than cochlear vibrations transmitted through the hair cells to the auditory nerve." |
| "I would like to propose that there is therefore no such thing as a cochlear sound in any demonstrable empirical sense, there are only in the first instance the sounds themselves we hear and hearken to. By simple inference all sound, as something heard in the world, is therefore non-cochlear (or more precisely a nonphysical phenomenon)." |
Riddoch proposes three types of non-cochlear sound:
- Synaesthetic -- the perception of sound via stimulation of another sense.
- Infrasonic sound -- sound waves below 20Hz can be detected by the skin and the chest cavity resonates at 80Hz and below. Riddoch also points to the example of profoundly deaf (from birth) percussionist Evelyn Glennie who maintains that hearing is a specialized form of touch (Glennie 1993).
- Auditory imagination -- including memory, imagination, hallucination, dreaming which all excite the auditory cortex.
