First example of "ringing in ears" sound design?

I have unashamedly copied a paragraph from this rather comprehensive article covering tinnitus as a movie trope -

The Cine-Files - The Tinnitus Trope: Acoustic Trauma In Narrative Film

They are discussing silence vs. whistling noise/ringing in ears [tinnitus]

...although Arthur Hiller’s The Out of Towners utilized the effect as early as 1970, onscreen ears remained mostly silent for the rest of the 20th century. The exceptions are few, but include important instances. The archetypal example of attenuated, tinnital sound deployed to represent wartime trauma occurs in Elem Klimov’s Come and See (1985), after the child-soldier protagonist survives an artillery barrage in a forest. Come and See is often mentioned as an influence on Steven Spielberg’s Saving Private Ryan (1998), which uses low-pass POA _{[Point of audition, the audio equivalent of Point of view]} sound in its first major battle and the tinnitus effect in the last. But while Saving Private Ryan is often mentioned as the early exemplar of this effect in American film, James Mangold’s Cop Land (1997), not only precedes it, but actually pivots psychologically and narratively on hearing loss and the sound of tinnitus.

They have also provided a fabulous timeline...

Edit
I just discovered that our sister site, Sound Design, had a part to play in that article - https://sound.stackexchange.com/questions/33129/name-and-examples-for-the-tinnitus-effect-after-explosions-in-films There's also a link to the complete article as a .pdf
