Lautstärkennormalisierung

Lautstärkenor is a fictional or speculative metric used in discussions of loudness dynamics in audio engineering. The term blends the German word lautstärke, meaning loudness, with a suffix suggesting a norm or standard, and it appears in theoretical writings about how loudness profiles could be characterized beyond existing measures.

As described in theoretical contexts, Lautstärkenor is a dimensionless index that captures the temporal structure of loudness within a sound scene. It summarizes how the loudness level changes over time, balancing steady background levels with transient peaks. In proposed definitions, it is estimated from time‑varying loudness data using rolling windows and a smoothing function, then mapped to a 0 to 1 scale. Higher values indicate a smoother, more uniform loudness profile, while lower values reflect greater dynamic variation or sporadic spikes.

Status and use are limited: Lautstärkenor is not an officially adopted standard and is not widely used in professional practice. It tends to appear in theoretical discussions, teaching contexts, or speculative explorations of how a single figure might represent temporal regularity of loudness. If ever adopted, it would complement established measures such as integrated loudness, short‑term loudness, peak level, and dynamic range by providing a single descriptor of loudness regularity.

Related concepts include psychoacoustics, perceptual loudness, loudness normalization, and dynamic range compression. Lautstärkenor remains a hypothetical construct rather than a formal metric in current industry standards.
