Brief tones inject extra frequencies called spectral splatter into the stimulus

Evidence

In sum, a long-duration tone has only one frequency: it is frequency specific. A shortduration tone can never be frequency specific. The duration of a tone has a drastic influence on the frequencies present in the stimulus, and has a primary effect of broadening the spectral peak of the stimulus. The increase in the frequencies present in the stimulus is called spectral splatter, which is characterized by the bandwidth, or the range of frequencies contained within the stimulus. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 178

  • DEFINE: Defines spectral splatter and bandwidth, key concepts for understanding how brief stimuli (like clicks or onsets) distort pure-tone perception.
  • XREF: Connects to the uncertainty principle in physics — frequency and time localization cannot both be sharp — and to windowing artifacts in signal processing.
  • QUESTION: Worth chasing: how does spectral splatter interact with hearing-impaired listeners’ reduced frequency selectivity?
