Tile installer keeps meowing during the job, is this a thing?

Twenty years in residential construction and I can tell you every crew has at least one guy with a verbal tic like that. I did a whole bathroom reno with a drywaller who whistled through his teeth every time he pulled a screw from the pouch. Nobody ever commented on it past day one. It just became background noise, like a nail gun. The chirping is almost certainly his way of marking the moment, kind of like how some guys say 'measure twice' out loud or tap the tile before snapping a cut. It's a rhythm thing. Tradespeople do weird little rituals to stay locked in during repetitive work, and tile especially, becasue it's all small precise movements for hours straight. Some hum, some narrate under thier breath, some aparently chirp like a cat.

If he's otherwise friendly and the work is clean, I wouldn't make a thing of it. The worst outcome here is you ask him about it in a way that lands wrong and he spends the last day and a half self-conscious about every sound he makes, wich can actually throw off a guy's flow. Tile guys especially hate being watched once they know they're being watched.

That said, if you're genuinely dying to know, there's a low-stakes way to do it. Next time he finishes a section, just say something light like 'my kids have started meowing at each other all day, thanks to you' with a grin. That gives him the opening to explain or laugh it off, and if it's some old habit from an old crew or a joke that stuck around, he'll tell the story himself. Guys in the trades love telling the story of where their dumbest habit came from.

One honest warning though. These things are contagious. A painter I worked with started meowing at the delivery driver as a joke one summer and half the crew was doing it by August. If your kids are alredy finding it funny, brace yourself, that sound is coming home with you either way.

I've observed that in extremely detailed trades like masonry or tile setting, the subconscious vocalizations often correlate directly with the mental state required to maintain precise tolerances. It is highly probable that the chirp is not merely random but rather a self-administered focus mechanism, similar to how some welders count their strokes or how we hear a crew humming a specific repetitive sequence during framing. The consistency of the sound suggests a rhythmic trigger. I wonder if his noise changes when he transitions from cutting to acutally setting the tile, perhaps indicating a shift in the physical concentration required for that paticular task. If the vocalization ceased entirely during the mortar application phase, it would suggest he is mentally locked into the placement methodology rather than just maintaining a general workflow.

The idea that the vocalizations are some kind of specialized mental focus mechanism for achieving precise tolerances is likely overkill. While the work demands accuracy, attributing it to a psychological requirement isn't supported. It seems way more probable that it is just a random, developed habit or some strange personal ritual. I've seen guys in detailed trades make all sorts of random sounds that have zero correlation to the quality of their layout or cuts.

I've seen that on sites, if the foundational work is solid, I can usually filter out a lot of noise. I once had a tile guy doing prep for a run in a high-end space and he was making these little vocalizations constantly. Even with the sounds, he got the layout and the initial mortar placement dead right on the first try. For me, that precision matters way more than the sound effects. As long as the cut list was accurate and the bedding was perfect, the chirping was just background noise to the job. It sounds like he has his rhythm and is hitting the specs.

I had a job where the contractor was using a highly specific cement mix for the floor. It was super sensitive to the ambient sound because any vibrations felt by the crew affected the leveling process. Even with that required focus, the tile guy's routine was hard to ignore. I ended up just wearing foam earplugs for the prep work, which actually made the chirping sound feel more distant and less distracting. It made the job feel more like a factory line, which helped me stay on schedule with the rest of the rough-in work. I wonder if that habit changes when the job moves past the initial layout and into the actual setting?

Update: watched closer today after reading these. The guy who said the chirps line up with focus kind of nailed it, because I noticed he goes silent during long stretches and only starts up again when he's measuring. Tried copying the sound back at him once when he dropped a spacer and he cracked up. Anyway, his crew friend apparently does the teeth whistle thing too, so maybe it's contagious?
