They do. The signal in question peaked at around 250 Hz, so in the bass range of human hearing.

But as noted in other posts the post you're replying to was based on an incorrect assumption - there's a corrected value in one of the comment threads, and the distance for it to be audible is much closer than originally posted, roughly the Earth-Moon distance.

On this point I recall when the gravity wave detector first detected a black hole merge, which is of course a LOT of mass and power. It was in the hearing range so they played a .wav. It unironically sounded exactly like a "PLOP" drop of water falling in a bucket - an irony that such a big event and a small event sound so similar.

This is both not surprising and surprisingly amazing
