I NEED help FAST...taking answers for only a few hours?

Question

thank you SOOOO much if you help me!!

i need to know "HOW does your ear and brain work together to find out WHERE sound is coming from???"

for example, if your eyes are closed and you here a sound in the distance coming from your right side, "how is it that you know its coming from your right?"

(yes, i've already asked this question, and yes its in the wrong category)

Answer 1

A right incoming sound would enter the right ear canal more so than the left. This in turn would cause the right ear drum to vibrate more than the left and such information would than be communicated to the brain via auditory nerves.

Outer ear
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Outer ear

External and middle ear, opened from the front. Right side.

The auricula. Lateral surface.
Gray's subject #229 1033
MeSH A09.246.272
The outer ear is the external portion of the ear and includes the eardrum.


[edit] Pinna, or auricle
The visible part is called the pinna and functions to collect and focus sound waves. Many mammals can move the pinna (with the auriculares muscles) in order to focus their hearing in a certain direction in much the same way that they can turn their eyes. Humans, unlike most other mammals, do not have this ability....


[edit] Ear canal, or external auditory meatus
From the pinna the sound pressure waves move into the ear canal, a simple tube running to the middle ear. This tube amplifies frequencies in the range 3 kHz to 12 kHz.

Answer 3

Auditory nerves and sound waves and amplitude of signal from either side. Your brain processes all of it and determines where the sound is coming from. Watch a deer sometime and watch them move their ears move. They're listening for anything in the area.

Answer 4

The central auditory system deals with the processing of auditory information as it is carried up to the brain. Central auditory processes are the auditory processes responsible for the following behaviors:

* Sound localization and lateralization
* Auditory discrimination (hearing the differences between different sounds)
* Recognizing patterns of sounds
* Time aspects of hearing (temporal aspects of audition): temporal resolution, temporal masking, temporal integration, temporal ordering
* Reduction in auditory performance in the presence of competing acoustic signals
* Reduction in auditory performance in the presence of degraded (less than complete) acoustic signals

Answer 5

Your right eardrum picks up the vibration of the sound and the auditory nerves take the impulse to your brain. And your brain tells you the sound is coming from your right.

Answer 6

sound waves travel in a straight line from the source in the direction pointed, unless they encounter an obstruction. your ear receives the sound and your brain automatically determines the direction the sound came from by the angle at which it entered the ear

Answer 7

Your brain and body are working together and have been sense you were a baby , so just because your eyes are closed your body still doesn't won't to get hurt..
