What would be the adjectivalform of something related to "sound"?

An example sentence would be:

There is some music that is the ____ equivalent of poetry to me.

It's not quite "musical" since I want the word to be more closely related to sound whereas music is a kind of sound. I thought of "sonorous," given its Latin root, but the definition of that is "(of a person's voice or other sound) imposingly deep and full" and I'm looking for a word that is more neutral. I also thought of "phonetic" but that is more closely related to speech.

Solution 1:

I think aural is commonly used in sentences like your example. Technically it's "related to hearing" but I think it gets your point across better than "related to sound," which is "sonic."

aural from Merriam Webster

of or relating to the ear or to the sense of hearing
