![]() But another central part of spatial hearing is monaural and binaural hearing, which is one-eared versus two-eared hearing. The coordinate system above works together in order for humans to get the most information out of sound. It is how far or near the sound is to a person, which helps to determine the source of the sound as well. ![]() ![]() It is the angle above or below the horizontal plane, which helps to identify if sound is coming from above or below.ĭistance is the more obvious part of the system. (The median plane is a vertical plane cutting through your head, perpendicular to “straight ahead”.) This helps to identify if sound is coming from the left or right side.Įlevation is the exact opposite of azimuth. There is a coordinate system that helps humans to do this, which includes azimuth, elevation, and distance.Īzimuth can be explained as the angle to the right or left of what is straight ahead, moving in an arc parallel to the ground. Without that, humans would likely make many mistakes about the auditory information coming in. This one task is extremely difficult, but also a crucial part of hearing. ![]() It requires being able to determine where sound is coming from. The human ear has to work really hard to make sense out of auditory information that is mixed in with many other sounds at the same time. Understand why auditory localization is difficult.īe able to describe the coordinate system for auditory scene analysis: azimuth, elevation, and distance.Īuditory localization is difficult to do for many reasons. ![]()
