It is a good question - I suspect that the sound of a breaking wave arises from the bubbles made by the impact 'ringing' - the fundamental mode of which will vary with T and the ratio of specific heats (gamma).
So I'd expect breaking waves on Titan to have fewer large bubbles (weaker gravity) but on the other hand the syrface tension of N2/ethane is lower than that of water, so might not bubbles be larger?
Either way, the speed of sound is 2/3 that of that at Earth's sea level - so a vibrating bubble ought to have a lower tone - if bubble sizes are like those on Earth, then the speed of sound alone will make crashing breakers sound deeper in pitch.
I think.
-fun!-

That's incredible! I might have to steal that idea

I’ll never descend into Jupiter, but that video was a little terrifying.

Don't quote me on this because I don't know the details of the mechanism - but I don't think it is designed to be retracted; it's supposed to be one of these do once and done kind of design.

they could just retract it while the engines are operating, wouldn't that work?

It sounds like exactly the kind of maneuver JPL would pull.

<polishes nails: I calibrated the speed of sound sensor (API-V) on the Huygens probe>
The speed of sound varies only with temperature and composition of the gas.
If you know the temperature (trivial) then you can infer the composition from the time taken for a 'ping' to traverse a small gap - from a transmitting element to a microphone.
Pressure affects only the 'loudness' of the ping, not the speed.
It's a good question how a waterfall might sound - or a breaking wave. That's not a trivial matter - as anyone who has poured hot and cold water into a glass and listened will attest.

Over which is an ocean of hypercompressed hydrogen at essentially the same density as the rock below.
The only transition is one of composition (mumble: and both seismic speeds) rather than density - which we seen in the terrestrial oceans.

using the engines (i assume) is an inevitablity
deployment might be a closed process
without the capacity to reinitialize

There is a sentence in that article that says “While some theorize that the core is a hot molten ball of liquid, other research indicates that it could be a solid rock 14 to 18 times the mass of the Earth” referring to the core
Would “solid rock” not mean a solid surface in this context?

Phewww I was really nervous about my eardrums there for a second. I’ll go ahead and cross that off my list of fears.

This is a great explanation, thank you!
