Premasking measurements are only reproducible with trained subjects and remain noisy

Evidence

The temporal region in which premasking appears was introduced in Fig. 4.17. Premasking is mostly measured with single masker bursts, and reproducible results can only be obtained from trained subjects. Even for these subjects, the reproducibility of the results is worse than in simultaneous masking or post-masking. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.
