tinniti

Erroneously formed by treating the etymon of tinnitus, Latin tinnītus, as a masculine noun of the second declension, in which, in the nominative case, the singular form ends in -us and the plural form in -i.

     Drs. Miot and Herck divide sounds in the ears into two groups: (1) The noises which really exist in the ears or their neighborhood. They are called entotic and periotic sounds respectively. (2) The true tinniti or auditory sensations which have no apparent cause. […] The tinniti caused by lesions without the auditory apparatus are of various kinds. […] In some mental diseases tinniti are prominent.

     N had a large number of subjective tones or tinniti, which made perception of the weak tones difficult and unstable. […] Liminal determinations were also attempted with N for Tone 3, but very distracting tinniti of about the same pitch made these determinations very irregular and unreliable. […] N shows a larger scatter of judgments than C or R, probably because of his tinniti. […] N’s tinniti continued to render his observations difficult. R, shortly after the completion of the preliminary experiments, contracted an infection in the eustachian tubes and middle ears which gave rise to numerous auditory disturbances, ranging from roaring and rushing sounds to the more common forms of tinniti.

Briand, “Otosclerosis Revision Surgery: Bad Pressure of Labyrinthine Fluids”, in Revista Portuguesa de Otorrinolaringologia e Cirurgia Cérvico-Facial‎^[1], volume XXVI, number 4 (overall work in Portuguese), Lisboa: Sociedade Portuguesa de Otorrinolaringologia e Cirurgia Cérvico-Facial, →ISSN, →OCLC, archived from the original on 19 August 2025, page 177, columns 2–3:

     When tinniti are due to a bad labyrinthine fluid pressure, the patient usually compares them with an ocean noise or a gas leak, wherever the labyrinthine fluid pressure is increased or decreased. […] A series of 376 French and foreign patients who underwent a revision operation have had a computorized survey over a two year period, for the hightone tinniti over 2000 Hz, which usually do not stop after the revision surgery. In 43% of cases, the intensity of the tinniti can be increased or reduced, after only a few seconds with this fluid pressure tinnitus test.
