Document Summary
Shortcut: there are in nite frequencies for our auditory system to react to each individual therefore, it responds to them similarly (freq. similar t within the same critical band). Consonance and dissonance: tones that sound simultaneously sound pleasing or displeasing. Starts at 4000 hz the high end of range and moves downwards for. Timbre: is the distinctive quality of sound produced by a musical instrument, overtones sounded by an instrument are responsible for this, frequency content: physical loudness of sound, changes across time: physical loudness of sound. Cochlea transfers the physical properties of wave trains into neural impulses, which then are transferred to the brain through complex networks of neural tracts. Transduction: process occurs during sensation; energy of one form (sound wave) must be converted into an electro-chemical energy (a impulse) e. g pressing keys on a keyboard send electrical signals in the device.
