Creature (Ornada) moan sound effect plays at max volume regardless of distance

I'm playing with OpenMW 0.45.0 and Tamriel Rebuilt 19.12, and creatures from the mod sound surprisingly loud, almost as if the sound playback isn't taking into account distance when determining volume. This is especially noticeable with the Ornada moan:

Morrowind\Data Files\Sound\TR\r\ornada moan.wav

To replicate the issue, turn up your "Effects" volume slider, and visit these coordinates:

player->setpos x 288057.406250
player->setpos y 64146.695313
player->setpos z 248.940369

Then, look towards the Ornada just above the cursor in this screenshot:

It is making "moan" sounds on loop. If you take a step back while it's making these sounds, they will cut out. If you approach the Ornada, it doesn't seem as if the sound is getting any louder. I'm not familiar with the Construction Set, but here's a screenshot of some records that might be relevant:

Unfortunately, I haven't been able to replicate this bug with vanilla creatures. I haven't tested Bloodmoon or Tribunal creatures. I have tested the same Ornada in the vanilla Morrowind engine (though with all MCP fixes enabled), and I can confirm that this issue is not present. The sound fades in and out with distance.

@Capostrophic mentioned that this might be related to #3674. @akortunov mentioned that there was once a sound issue with Riekling screams. Does this sound like the same issue? If it helps, I'm running OpenMW 0.45.0 on Windows.
