Organisms evolving independently on different planets will probably end up with the ability to hear things at the same frequency range as humans. That’s because the sound a predator makes as it approaches would be in the same spectrum regardless of atmosphere. Organisms that could react to these frequencies would have an advantage and survive.
I read about this idea in Project Hail Mary.

When asked to draw a random number between 1 and 10 and any color, most people choose the number seven and the color blue. Some potential explanations is that 7 is a lucky number in many cultures and blue is pleasant (or at least not unpleasant or unlucky).
