A major problem with
testing temporal resolution is that when we make temporal changes in a
frequency-specific sound, we also make spectral changes. For example, a long
duration tone has a single peak in its spectrum, but when we make the same
sound short in duration by turning it on and off abruptly, sound energy
spreads to adjacent frequencies . This phenomenon is called Òspectral
splatterÓ. The problem is that a listener could tell, for example, that the
duration of the sound changed by detecting the change in the spectrum, not
the time waveform.
