Subjective duration distortion is largely independent of loudness 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
