Document Summary

Ears on either side of the head give us stereographic hearing. Timing method: noting direction of sound by which ear is stimulated first: works best with low frequency. Volume method: nothing direction of sound by which ear is stimulated most vigorously: best with high frequency sounds. 1) sound waves travel though air, hit ear drums, and give us the real" sound of our voice what others hear. 2) sound also travels from the larynx through bones in our skulls to give us the impression that we have a deeper, more resonant voice. Human hearing is worse than most mammals, but specialized for understanding and producing speech. Motor and sensory cortex strong focus on control of mouth, tongue, jaw: flexibility in speech perception system. Lips and jaw movement changes for accent: conflict perceptions from hearing and visual systems. We pick up auditory and physical cues. Mcgurk effect same sound but different shape of the mouth. Complete or partial deafness: congenital, environment.
