Most sounds fluctuate naturally over time and frequency. Normally
hearing listeners can make use of these fluctuations, and get
information from sound snippets that have a preferable amount of signal
energy. This phenomenon is called dip-listening. Dip-listening is
something that hearing impaired listeners and cochlear implantees
struggle with. It would be great if we could restore it somehow.
- Dip-listening: What segregation cues
if any can help dip-listening?
