Sentence-final words were counterbalanced across all four sentence noise conditions.

Evidence

Each sentence-final word was only heard once, either in the context of an HP or an LP sentence, and half the sentences of each type were heard with high or low SNR. Across all listeners, each sentence-final word was heard an equal number of times in all four conditions (sentence type × SNR). — Dijk, Pim van, Physiology, Psychoacoustics and…, 1268
