· PREDICT and then MEASURE peoples’ ability to locate the source of a sound when
blindfolded and not allowed to move their heads
· CHANGE A VARIABLE by allowing the subjects to move their heads
· CALCULATE the class averages for correct and incorrect answers for each location
of the sound source
· DIAGRAM the pathway that sound signals follow from the ear to the brain
· DISCUSS advantages of using vision, hearing, or both to locate a sound source
· DESIGN AND CONDUCT experiments to study the sense of hearing further, for
example:
· TEST the ability to locate a sound source with one ear plugged
· SIMULATE animal hearing with fabricated outer ears
· DEVISE a test for the ability to hear different intensities of sound
· INVESTIGATE human communication: how do we decode the meaning of
words – if they are muffled, what cues do we use to decipher them?

Hearing (or audition) is the sense of detecting sound, that is, receiving information about the environment from vibratory movement communicated through a medium such as air, water, or ground. It is one of the traditional five senses, along with sight, touch, smell, and taste.Both vertebrates and arthropods have a sense of hearing. In humans and other vertebrates, hearing is performed primarily by the auditory system: Sound is detected by the ear and transduced into nerve impulses that are perceived by the brain.
