    Ah... I see.
    Let me quote myself:
    Let me make what I mean more tangible with another example. To do this, I'll first pose the following question:

    Do trees make sounds when they grow? It's been proven that trees emit ultrasound when under water stress, but can you listen to a tree growing?

    One could make continuous recordings under isolated laboratory conditions over many years to check if the tree makes sounds as it grows - that is, if it displaces the air in such a way that it causes periodic vibrations. If we were to record something, we could then pitch it up or down into the human audible range. We would have a sound recording and have processed it so that we can hear it. This would be audification.

    Alternatively, we could saw a tree open and look at its annual rings. These annual rings tell us quite precisely how fast a tree grew in its respective life phase. We could then take this data and make derived calculations about how much air the tree probably displaced during its growth in the respective phases and how quickly (or slowly) the air was probably displaced. We can then build a model with which we try to calculate whether it was probably more a case of static displacement or periodic displacement, etc, etc... Eventually, we've built ourselves a really great model. And from this model, we then try to derive the sounds of the respective growth phase and then synthesize them. We never had a sound recording. We still don't actually know for sure if this sound ist right or if there was any sound at all. We created a model based on tree ring data, on the basis of which we synthesized sounds. That would be sonification.

    A sonification model is an interpretation. It does not prove that a sound exists. It merely answers the question:
    IF we were to represent this growth data as sound, what would it sound like?
    Similar applies to what NASA did.

    ---

    EDIT:

    I think the core of the issue is a small but crucial misunderstanding that comes down to language. It all depends on how you define "sound".
    In german, we have two (actually more) useful terms for this, both of which just translate to "sound" in english:
    1. "Schall": This is the purely physical definition - A wave propagating through a medium. According to this definition, wherever there's a medium in the universe, there is Schall. So, the pressure waves in the gas around a black hole are sound. The impact of two asteroids colliding also creates structure-borne sound.
    2. "Geräusch": This is what we perceive as an event. It's an audible, in an other way perceivable or directly measurable sound event.
    And this is where the distinction lies: While the pressure fluctuations around the black hole are physically "Schall", their frequency is so extremely low (one oscillation over millions of years) that they don't exist for us as a "Geräusch". You can't set up a microphone and record them, no matter how good your equipment is. You can't feel them in your chest. You can only detect them indirectly by its x-ray history data.

    So, in a way, you are right. "Schall" exists, but you can't experience it as a "Geräusch", which is why any audible version must be an artistic interpretation by definition. :winker:
