I’ve heard this about mechanical electronic signage used for team dashboards 30-40 years ago.

You’d sit in the office with your back to it and the clicky clacky sounds would be going every so often when the content updated. but people would know the specific clicky clacky sound that required them to turn around and read the sign based on their job function.

I’ve also heard of day traders mapping stock tickers or other data into sound and having headphones on all day with it
