Auditory temporal resolution in birds: discrimination of harmonic complexes.
The ability of three species of birds to discriminate among selected harmonic complexes with fundamental frequencies varying from 50 to 1000 Hz was examined in behavioral experiments. The stimuli were synthetic harmonic complexes with waveform shapes altered by component phase selection, holding spectral and intensive information constant. Birds were able to discriminate between waveforms with ...

We review recent studies that examine the temporal resolution of the avian auditory system as measured behaviorally in a small songbird, the Zebra Finch (Taeniopygia guttata). These birds naturally learn and produce complex harmonic vocalizations. Here we created complex harmonic stimuli that simulate the fine temporal properties of these natural calls in order to probe the possible parallels b...
متن کاملRelative salience of envelope and fine structure cues in zebra finch song.
Zebra finches produce a learned song that is rich in harmonic structure and highly stereotyped. More is generally known about how birds learn and produce this song than how they perceive it. Here, zebra finches were trained with operant techniques to discriminate changes in natural and synthetic song motifs. Results show that zebra finches are quite insensitive to changes to the overall envelop...
متن کاملRecognition of Non-Harmonic Natural Sounds by Small Mammals Using Competitive Training
Animals recognize biologically relevant sounds, such as the non-harmonic sounds made by some predators, and respond with adaptive behaviors, such as escaping. To clarify which acoustic parameters are used for identifying non-harmonic, noise-like, broadband sounds, guinea pigs were conditioned to a natural target sound by introducing a novel training procedure in which 2 or 3 guinea pigs in a gr...
متن کاملPhase effects in masking by harmonic complexes in birds.
Masking by harmonic complexes depends on the frequency content of the masker and its phase spectrum. Harmonic complexes created with negative Schroeder phases (component phases decreasing with increasing frequency) produce more masking than those with positive Schroeder phases (increasing phase) in humans, but not in birds. The masking differences in humans have been attributed to interactions ...
