amplitude - refers to the loudness
Intensity - power carried by a wave per unit area
timbre - tone color or quality/ complexity
3 charactersitics of sound - loudness, pitch, timbre
loudness depends on the __ - amplitude of vibration
pitch depends on the - frequency
timbre/ quality depends on the - wave form/ overtones
concept of hearing shapes - the ability to perceive and identify the shape of objects
based on how they occlude or reflect sound waves
importance in psychoacoustics - the phenomenon demonstrates the auditory systems
capability to interpret spartual and geometric information from sound, similar ot
echolocation used by bats and dolphins
hearing silent shapes refers to - sound occluding surfaces
sound occluding surfaces include what three things - positioning, judgement of space,
affordance judgement
implications of sound occluding shapes - they suggest that the auditory system can
extract detailed geometric information from sound occlusion patterns
Gestalt grouping principles - Proximity, similarity, good continuation
proximity - sounds that are close together in time or frequency are more likely to be
perceived as part of the same auditory stream or object
What is the concept related to sounds with similar timbres being grouped together? -
Similarity in timbre
What is the concept related to sounds with similar rhythmic patterns or tempos being
perceived as coherent auditory stream? - Similarity in tempo
in good condition - sounds that follow a smooth and continuous pattern are more likely
to be grouped together
, Primitive grouping principles - shared time, shared freq ranges, spacial location
What is the role of timbre in auditory scene analysis? - The complexity of the waveform,
overtones, harmonics, and source identification contribute to the perception of different
auditory objects or streams.
How does intensity influence auditory scene analysis? - The amplitude or loudness of a
sound can influence its perceptual grouping with other sounds.
In auditory scene analysis, how does temporal change play a role? - Rhythmic patterns,
tempo changes, and the temporal evolution of sounds play a role in auditory scene
analysis.
What effect does frequency change have on auditory scene analysis? - Changes in
frequency content, such as pitch or spectral shifts, can affect the grouping of auditory
components.
Why is the perceived spatial location of a sound source important in auditory scene
analysis? - The perceived spatial location of a sound source is a crucial cue for auditory
scene analysis and segregation.
the primary tastes - sweet, sour, salty, bitter, umami
papillae - taste buds
super-addictive activation - combining subliminal cherry aroma with sugar taste
enhances the perception of sweetness
multiple neural connections - the brain integrates multiple sensory inputs to create a
unified flavor perception
adaptation - continuous presence of a stimulus lowers sensitivity and increases the
threshold
Cross Adaption in olfaction - adaptation to one substance lowers sensitivity for another
substance
cross enhancement - adaptation to one taste can make you more sensitive to another
taste
dysgeusia - Damage to a taste nerve that can lead to the perception of a taste that is
not present.
ageusia - inability to taste
