Uniform exciting noise loudness grows as intensity raised to the 0.23 power

Evidence

This dependence can be approximated for large levels of the uniform exciting noise by relating its intensity to the loudness produced, using a power law with an exponent of 0.23. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 1255
