Document Summary
Sound travels through the air live a wave. Amplitude is the y exist, so the higher the amplitude, the higher the sound. The frequency determines our perception of pitch. Between the ears and the brain: Lots of sound processing happens along the auditory pathway between the cochlea and the auditory cortex. Sound to the right ear is processed by the left hemisphere. Sound processing in the brain: Primiar auditory cortex is the first place in the cortex that is devoted to sound processesing. Every day acoustic environments are noisy. We must be able to segregate or separate different sounds when they occur simultaneously (known as concurrent sound segregation). We must also be able to group or integrate over time (sequential sound segregation). Like vision, the way we perceive our auditory environment is thought to follow some gestalt grouping principles. Concurrent sound segregation: grouping by frequency. This represents a complex harmonic sound. The fundamental frequency is 200 hz.
