PSYB51H3 Lecture Notes - Lecture 10: Auditory Scene Analysis, Fundamental Frequency, Sine Wave
Document Summary
Hearing in the environment: today the lecture is about music perception, speech perception, and the overall perceptual aspect of these auditory functions, we will also look at attack and decay of how sound ends. Harmonics: always have a very regular pattern, the graph has the energy (amplitude of sound energy on the vertical axis) It will still sound like the pitch of the fundamental frequency: the first graph is the harmonic sound with a pitch 1 hz, if you delete whatever generates the sound, it still sounds like the original pitch. Sehar qureshi: even in the second graph, where there is little left of the harmonic spectrum, the fundamental frequency can be heard even though it is not there. So it seems that using temporal frequencies, can allow us to perceive fundamental frequencies. Complex sounds (continued: definition of timbre is on the slide*
