Helioseismology - How do you listen to the Sun?

I understand we can use seismology to study our Sun and from that deduce the internal layered construct.

Based on the fact that Seismology is pressure waves like sound.

How do we detect/listen/analyse the Sun, when we have effectively have a vacuum in space between the Earth and the Sun?

So we do not actually listen to the sun on the Earth by pressure waves being detected locally.

We are instead observing and measuring oscillations in the Sun and converting them to sound.

As the surface of the sun is a boiling dynamic seething mass, how can we detect anything other than the largest of oscillations

I recommend this book:

Sunquakes, Probing the Interior of the Sun   J. B. Zirker The John Hopkins University Press 2003

Observe; collate; conjecture; analyse; hypothesise; test; validate; theorise. Repeat until complete.

This is an excellent PBS Nova episode that covered that very subject.

Starting at about 11 minutes they discuss helioseismology.
I was not smart enough to know it was impossible to do what I did.
