Well we had better add this permutation of hearing and not hearing.
Whatever the flavor of the grammar, it is the INTENT of the heart, FREE WILL and CHOICE that divide the hearers, non-hearers, doers and non-doers, choosers and non-choosers.
[Act 7:54 KJV]
When they heard (akouō) G191 these things, they were cut to the heart, and they gnashed on him with [their] teeth.
The KJV translates Strong's G191 in the following manner: hear (418x), hearken (6x), give audience (3x), hearer (2x), miscellaneous (8x).

And see the verb you're defining in Rom10:14, then go to the noun form of the same word in Rom10:16-17 as @Kroogz posted, then go to the verb form again in Rom10:18.
Put it all together and it's very clearly just telling us God spoke Good News > men proclaim that Good News which God spoke > people hear that Good News > some believe/obey that Good News and some don't.
Then look at Rom10:18 and see that Paul clarifies it's just about hearing the voice/the sound which IMO puts @Cameron143 distinction about "audible" hearing to rest.
This is all about audible hearing beginning with men who audibly heard God speak His Good News and who were sent to audibly proclaim His Good News to others could audibly hear His Good news and obey His Good News and thus obey Him / believe His Good News and thus believe Him. And this belief/obedience is called Faith. And Faith FROM something heard/the Gospel and something heard/the Gospel THROUGH [a] spoken word/statement of/from God.
This is part of the problem with this Reformed interpretation. It's coming back into Rom10 and redefining very basic words.
