My theory is that Africans have a higher sensory threshold overall. That is, they require a more intense stimulus for an equivalent reaction, compared to other races.Not a video with an instance of the chirp, but rather a quick one about the phenomenon. I think it makes an interesting case about genetic differences in hearing being a potential cause.

Unfortunately it seems like she's going to take that valuable information with her to the grave. If you look at her replies to the comments, you don't see any justification at all. There's no replies like, "It's not a big deal!" Or, "I can't hear it," or even, "If you want me to change it, you pay it." Or literally anything.Replacing the battery could help stop a tragedy.
I really wonder if they can hear the chirp at all or if they have blasted their hearing so badly that they lost frequencies that high. She does kind of yell through the entire video.
The people in the comments are saying that there are SONGS with the chirp in it LMFAOI'm back with some interesting evidence from Reddit.
In this post, a black guy asks the Internet, "what's the deal with people commenting about smoke alarms chirping?" Specifically just the comments. He mentioned no chirp in any video that he's seen, just that he's seen comments about it.
This shows us one of two possibilities.
1) He can't hear the chirps. Even in a video, he's deaf to them.
2) He can hear them, but they're as irrelevant as someone having a single gray hair.
Both would say a lot about his perspective.
This seems to be not too far off from how most black people approach the issue.
