Silence intervals of half a second to a second aid auditory discrimination accuracy

Evidence

Regardless of the exact mechanism, the data suggest that a period of silence of approximately 500 ms–1 s is beneficial to discrimination accuracy. It should be noted that the situation in this test is different from that in some standard audio product listening tests where the listener can switch immediately between differently processed versions of a program item [my italics] without restarting playback. With this sort of continuous playback switching, performance may be better than is suggested by the 100 ms RI (retention interval) condition. This is likely to be because only the applied processing is changing rather than there being an additional change in spectrum between the offset of one stimulus and the onset of another. — Toole, Floyd E, Sound reproduction- the acoustics and…, 99
