Deficits in any perceptual dimension impair everyday communication

Evidence

Each series contains four tone pairs of different duration and frequency difference: First 500 ms and 10 ms at the smaller frequency difference, and then 10 ms and 500 ms at the larger frequency difference. The following frequencies are used: 2000 Hz, 2010 Hz, 2040 Hz; 500 Hz, 505 Hz, 525 Hz. For example, a frequency difference of 10 Hz between 2000 Hz and 2010 Hz can be discriminated at 500 ms (1) but not at 10 ms (2). On the other hand, a frequency difference of 25 Hz between 500 Hz and 525 Hz can hardly be discriminated at 10 ms (7) but is clearly audible at 500 ms (8). — Professor Dr.-Ing.

Interfering noises that have similar rates of variation as speech are particularly difficult to deal with, as they fool our higher-order processing centers into attending to them as if they are speech. Because of this, their effect is often more severe than a simple measurement of level would indicate. — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 2481 (#expands, via linked claim)
