Rohloff Hub Noise Due to Bottom Bracket or Crank Issues

Confirm this cause if the noise occurs at the exact same point in every single crank revolution, regardless of the gear selected. Inspect the crank interface, chainring bolts, and the bottom bracket assembly. Listen for rhythmic metallic tapping or creaking that coincides specifically with the load applied during the downward phase of the pedal stroke, suggesting a mechanical interface issue outside of the rear hub.
