Speaking is the miraculous gift, not hearing. Those who receive the gift are the speakers, not the hearers.
In v.8 & 13, those of foreign tongues, hear the gifted disciples. What do they hear? Of course, their native tongues, spoken by the disciples gifted with tongues. And it amazes them, that they speak each of the native tongues of the people coming from other nations and places.
You speak of some sort of a gift of supernatural hearing received by the hearers, while the passage speaks of a supernatural gift of tongues received by the speakers, that is, the disciples, in whom the Holy Spirit had come upon.
And so, I will believe what I read in those passage, with regards the gift of tongues, as being the supernatural ability of the speaker to speak in tongues which otherwise he could not without the gift.
Acts 2:4 And they were all filled with the Holy Spirit and began to
speak with other tongues,
as the Spirit gave them
utterance.
