<P> Pitch is perceived as how `` low '' or `` high '' a sound is and represents the cyclic , repetitive nature of the vibrations that make up sound . For simple sounds , pitch relates to the frequency of the slowest vibration in the sound ( called the fundamental harmonic ) . In the case of complex sounds , pitch perception can vary . Sometimes individuals identify different pitches for the same sound , based on their personal experience of particular sound patterns . Selection of a particular pitch is determined by pre-conscious examination of vibrations , including their frequencies and the balance between them . Specific attention is given to recognising potential harmonics . Every sound is placed on a pitch continuum from low to high . For example : white noise ( random noise spread evenly across all frequencies ) sounds higher in pitch than pink noise ( random noise spread evenly across octaves ) as white noise has more high frequency content . Figure 1 shows an example of pitch recognition . During the listening process , each sound is analysed for a repeating pattern ( See Figure 1 : orange arrows ) and the results forwarded to the auditory cortex as a single pitch of a certain height ( octave ) and chroma ( note name ) . </P>
