The real question should be, "did it make a sound" ?

Recognizing your valid points, the quick and easy answer is...
yes, it made a sound.
Whether or not someone actually 'hears' it, sound waves exist as variations of pressure in a medium...such as air.
Think of it this way, if a deaf person watches a tree fall over, but can't hear it...did it make a sound?
Although, you're point has been a philosophical question... that's been around a long time.

I know, I know, I can sometimes be a
'buzz-kill'...on intended lighthearted subjects
Sorry.
As to the post in question, I don't think the lack of seeing people in pools at any one point in time...is indicative of whether they are being used.
