Sight is to Visualisation as Sound is to?

Since you are mentioning 'abstract information' I think you might use the word

sonification:

Sonification is the use of non-speech audio to convey information or perceptualize data.[1] Auditory perception has advantages in temporal, spatial, amplitude, and frequency resolution that open possibilities as an alternative or complement to visualization techniques. (Wikipedia).

This article by Thomas Hermann deals with the definition of 'sonification' and suggests that it should be used as an analogue to 'visualisation':

... we suggest using sonification with the same level of generality as the term visualization is used in visual display.

P.S. SomethingDarks's suggestion helped with finding this word, so thank you. I think auralization is something a bit different, though.
