(b) Auditory sensation evoked by the oscillation described in (a)." [2]
The GCD of the frequency of all harmonics is the fundamental (dashed). A low pitch (also known as the pitch of the missing fundamental or virtual pitch [3]) can sometimes be heard when there is no apparent source or component of that frequency. This perception is due to the brain interpreting repetition patterns that are present. [4][5][6]
There are also numerous vowelless interjections and onomatopoeia found more or less frequently, including brr or brrr, bzzt, grrr, hm, hmm, mm, mmm, mhmm, sksksksk, [13][14] pfft, pht, phpht, [7] psst, sh, shh, zzz.

While experiencing an auditory hallucination, the affected person hears a sound or sounds that did not come from the natural environment. A common form of auditory hallucination involves hearing one or more voices ...
Shock wave. The sound barrier or sonic barrier is the large increase in aerodynamic drag and other undesirable effects experienced by an aircraft or other object when it approaches the speed of sound. When aircraft first approached the speed of sound, these effects were seen as constituting a barrier, making faster speeds very difficult or ...
Sound changes occurring without a spelling change. The digraph gh was pronounced [ x ] in Middle English in such words as light . Sound distinctions from foreign languages may be lost, as with the distinction between smooth rho (ρ) and roughly aspirated rho (ῥ) in Ancient Greek , represented by r and rh in Latin , but merged to the same [r ...
