Yeh, 30ms is still inside the haas delay.
If you are a professional listener (sound engineer, musician, dancer) then you can probably perceive it (in a similar way that eyes theoretically only need 25fps, but 60/120/144 is noticeably better).

In 30ms, sound can travel 10 meters.
So, if you've ever had a conversation with someone across a classroom, you've had a conversation with 30ms latency.

For data, 30ms is 8100 km for electricity over copper, or 6000km for light over fibre.

Meaning 30ms over fibre (considering no transmission delays) would be roughly the direct distance between US and UK.

So yeh, 30ms is nothing
