Duration perception distortion is largely level-independent above 30 phon

Evidence

The effect, which must playa strong role in music and speech perception, is not too dependent on loudness level if loudness levels larger than 30 phon are used. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing. Eberhard, Psychoacoustics- Facts and Models, 1489

Adaptive loudness scaling requires roughly 15 times fewer trials than fixed-level procedures.
Frequency-domain differences track perceived distortion better than time-domain ones
Level JNDs grow fivefold as tone-burst duration drops from 200 to 2 ms
Listener response uncertainty concentrates in the 5-25 CU loudness range.
Musical note duration flattens reflection thresholds much like room reverberation does
Subband and modulation power both strongly predict perceptual distances in consonant perception
Subjective duration distortion is largely independent of loudness above 30 phon
Temperament matters less in fast passages where frequency is ill-defined
