|---|---|---|---|---|---|
| show | The sound of only one frequency

| What is the fundamental note? | show 🗑
|
||||
| show | physiological perception, depending on sound pressure, spectrum of the harmonics and physical duration.
🗑

| Describe the missing fundamental. | show 🗑
|
||||
| show | Basilar membrane vibrates @ frequency of stimulus -> cells fire at this location -> leads to pitch perception. But humans can discriminate between 1000-1003 Hz, so this is only an adequate explanation for > 5000 Hz

| What is Timing Theory? | show 🗑

| Who developed the Place Theory of pitch perception? | show 🗑
|

| show | Research has shown music training early on in life benefits the brain later on in life. Trained musicians show a 25% increase in the region of the auditory cortex that responds to piano tones, compared to non-musicians.
🗑
|
||||
| show | Groups of neurons of the auditory system respond to a sound by firing APs slightly out of phase with one another so that when combined, a greater frequency of sound can be encoded and sent to the brain to be analyzed (Phase locking)

| What about stimuli from 1000-5000 Hz? | show 🗑
|
||||
| show | The superior olivary nucleus.
