Damn that guy has an annoying voice.

I'm glad you brought that up because (no joke) nobody can actually explain how aerodynamic lift works, much less how a plane can fly upside down: https://www.scientificamerican.com/article/no-one-can-explai...
Planes fly because of climate change. Which causes us to need more climate change as we get more flights. Sad but true.
Interesting. I heard similar sounds from a rather big French train station speakers recently. For me it looks like it’s just a bug from the amplification system.
I feel like I'm going crazy when I read things like this. To me that is very clearly a human voice. Does it not sound that way to you?
But anyway, I'm playing devil's advocate with myself. I agree that's definitely a human voice on the intercom.

Apparently there is a compact flash card to play music and the pre-recorded announcement over the loud speakers. I wonder if someone replaced the standard announcement with a 5 hour long file with intermittent burps and groans....
They would probably notice that but it does seem like some former passenger most likely installed something that's patched into the system. It may just be a recording from a flash drive. Or it could also be more sophisticated and patch into the wifi as well. You could also imagine it having a microphone for added hijinx but none of the interactions seem to suggest that.

Age, probably. Young kids aren't that smart.
A lot of what I am complaining about is actually people older than me peddling "advise" - how to become a data analyst (no understanding of data required!). It just feels like Facebook-tier people given the content equivalent of a machine gun.
That sounds plenty plausible to me.
For those interested in the various aircraft systems for PA (public address) and aircraft status system for aircrew, I found this interesting training doc PDF online [1] for the A320/321. I have been looking at section "03-010 CABIN INTERCOMMUNICATION DATA SYSTEM" It does not mention the "medical intercom jacks" in overhead bins that are mentioned at the end of the article [1]: https://caisatech.net/uploads/XXI_3_AIR…
A bit of searching for airplane medical communications jacks turned up this picture: https://aviation.stackexchange.com/questions/12776/how-are-t... Jacking into that would not be inconspicuous.
That seems unlikely. Definitely sounds human
As an audio person, musician, producer blah blah, that is totally human. Likely recorded and filtered a few times. By the inflections I think Eastern European. The sound of it reminds me of a Slavic based vocal upbringing. Doesn’t seem like North Korean, Latin, or North American to me.
Probably about a couple minutes of audio looping somehow at the source. Far too many for it to be a hardware exploit because honestly who wants to invest that much in this kind of prank? This isn’t Zug Super Bowl level[0].
My guess is they’re coming through the least secure provider for a third party service - probably the WiFi enterprise thru being on the inside of them - and AA is their first playground where people are noticing. How they get from there to the intercom is probably buried deep in a couple audio wires plugged into overlapping sources unintentionally or there is some kind of frequency band that isn’t shielded properly so it’s possible to push the audio signal over something else and cause garbled noise and almost impossible to find.
Like, in the past it was funny when picking up FM radio signals through my guitar amp, but it sucked when trying to have a serious jam session and talk between playing. Audio signals can be really powerful compared to other delicate systems IMO.
Definitely curious and want to see how this unfolds!
This reminded me of something that happened to me in college. This is a unlikely sounding story, but I swear it's the truth. I started noticing some odd sounds in the Student Union building. One day I had some time and decided to investigate. I realized it was coming from a fire alarm. I stood under the alarm and listened for a while. The alarm was quietly whistling "Harder, Better, Faster, Stronger" by Daft Punk.

I've flown American six times in the last ten days, and four of the flights had chaos with the entertainment system. No groans or heavy breathing on the PA, but flight attendants had to "reboot the system" once or twice every flight.
