Auditory systems for localizing sound
Auditory signals are able to integrate information from both ears in order to identify the sourse of a sound. This helps with allerting danger, potential mates, or other situational information that is necessary for survival and normal activities throughout the day. Humans have an accuracy of about 1 degree horizontally around their head, and may animals demonstrate even higher accuracy. There are two types of binaural (two-ear)cues that help with localization on the horizontal plane; intensity and latency.

Explaining an Everyday Auditory Phenomenon
A musician plays a note on a guitar. They then tighten a string and pluck it more gently, producing a second note that is perceived as higher in pitch and quieter. What physical changes in the sound waves correspond to this perceptual change?

Spectral cues in localization of auditory information
A person finds it much more difficult to pinpoint the exact location of a sound source when it is positioned directly in front of, behind, or above them, compared to when it is off to one side. Based on the principles of auditory localization, what is the most accurate explanation for this phenomenon?
