Mid Term Flashcards
Oval window,
area near stapes, helps relieve pressure from fluid movement inside cochlea.
Auditory stream segregation
Able to seperate out different lines based on characteristics like on pitch level. Falls under gestalt principle of law of proximity.
Ossicles
Smallest bones in body, hammer anvil stirrup, malleus incus stapes, mechanical to fluidic transduction of soundewaves, located in middle ear.
Organ of corti,
Toon topic membrane, activates hairs cells where maximally displaced. Part of cochlea.
Hertz
Freuqncy, physical, psychologically pitch.
Cycles per second. Named after friederick. Ex. 440
Basilar membrane
Located in cochlea, toner pic, vibrates, stimjlTes organ of corti?
Periodicity pitch
Hear lore note that I not there, using upper harmonics, it is faint, higher pitch added lower fundamental heard. Constructed it in our mindl phase rela. Interpreted repetiotn of 200bps as lower pitch.
Law of pragnanz
.by kaffka
Filled pregnant with meaning.
States we will interpret what the prevailing conditions allow us to see, organize what makes sense to us, same as gestalt, whole greater than parts.
Use our previous experince to allow us to see things.
Subsidiary laws,
Auditory stream segreagtion upper lore line. Hear at two different links. Segregate parts by there melodic height.
Taonial fusins two notes
Heard as one note.
Only for non musicians,
Organ of corti
Both hair cells, and membrane,
Basilar membrane
Displaced, hair cells, tactile membrane, send signals to brain, shearing along factorial membrane, withing cochlea, sensitive pitch loudness, wheee displaced determin ensemble of pitchs, loudness afftes number of hair cells displaced.
Critical bandwidth theory
P. 164
Semitones overlap on membrane, perceive as dissonance.
Interference of tones within critical bandwidth. Only with pure tones does this work,
1/4 of distance of critical bandwidth has maximal dissonance.
But low notes within one bandwidth.
Holds for non musicIns,
Information complexity
Psychophysical dimension.
Complexity cognitive, ability to understand music, depends upon us, expereince,
Inverted u, liking,
More familiar less like, less complex.
Salient aspects of melody, how do we organize melody
Contour, high low, and gestalt psychology.
Timbre affect pitch, q
Bright timbre, dark,
Found ppl made mistakes flat bright, flat stayed same or went up in pitch when same or was darker, or opposite,
Shepard tone, timbral content changing, disguise effect of timbre,
