When players descend into the Irrigation Tunnels in Badlands (approx. 5+ meters underground), surface sandstorm audio effects continue to play at full volume throughout the entire tunnel network.

The game fails to attenuate or occlude surface environmental weather sound effects (Indoor Sound Occlusion / Sound Attenuation) when the player is inside subterranean structures, breaking audio immersion.

1. Wait for a sandstorm event to begin on Badlands.

2. Enter an Irrigation Tunnel and descend at least 5 meters underground.

3. Move deep into the tunnel network away from the entrance.

4. Listen to the environmental ambient sound.

Surface weather sound effects (sandstorm wind/howling) should be significantly muffled, attenuated, or replaced by subterranean ambient audio as the player goes deeper underground.

Actual Result: The sandstorm audio continues to play at max volume everywhere inside the deep tunnel network, as if the player were standing directly on the surface.
