Auditory Scene Analysis
What process allows the brain to separate multiple sounds into different perceptual streams?
Auditory scene analysis
What term describes the quality of a sound that makes two instruments playing the same note sound different?
Timbre
What psychological experience corresponds to the frequency of a sound?
Pitch
What auditory cue helps determine how far away a sound source is based on its loudness?
Intensity
What is categorical perception in speech?
The tendency to perceive speech sounds as belonging to distinct categories rather than a continuous range
What principle groups sounds that occur close together in time?
Temporal proximity
What aspect of a sound describes how it begins and reaches its maximum intensity?
Attack
What is the interval between two frequencies with a 2:1 ratio?
Octave
What phenomenon occurs when the brain groups sounds with similar frequencies together?
Grouping by Similiarity
What acoustic feature distinguishes different vowel sounds in speech?
Formant Frequencies
What principle groups sounds with similar frequencies together?
Similarity in frequency
What aspect of a sound describes how it fades after the peak intensity?
Decay
What term describes the perception of pitch moving higher or lower with frequency?
Tone height
What auditory principle groups sounds that start and stop at the same time?
Common Onset
What problem occurs because speech sounds change depending on the surrounding sounds?
The Lack of Invariance Problem
What effect causes us to perceive sound from the first arriving signal when echoes follow quickly after?
The precedence effect
What term describes the distribution of energy across frequencies in a sound?
Spectral shape
What sound quality is shared by notes separated by an octave?
Tone chroma
What is harmonic grouping in auditory perception?
The tendency to group frequencies that are related as coming from the same sound source.
What is coarticulation in speech perception?
When phonemes overlap because speech sounds influence each other during production.
What phenomenon occurs when tones separate into two different perceptual streams instead of one?
Auditory stream segregation
What property of sound allows us to recognize a violin versus a piano even if they play the same pitch?
Harmonic structure
What is produced when three or more musical notes are played simultaneously?
A chord
What perceptual phenomenon occurs when the brain fills in missing parts of speech that are masked by noise?
Phonemic Restoration
What brain region is primarily responsible for understanding spoken language?
Wernickes Area
