in order to figure out where sounds are coming from we ____them
Answers
Answer:
Having two ears helps us to determine the direction of sound waves.
Time lag, wave length and tone - all these factors play important parts for the brain when determining the direction of sound.
In the following description, they are treated under separate headings, but when a person registers a sound, all three factors interact, helping to determine the direction from which the sound originates.
Time lag
Time lag is of particular importance when determining so-called impulse sounds like a click or a bang.
If a sound comes in at an angle to the right of the face, the direction of the sound waves means that the sound will not reach both ears at the same time.
The time lag is due to the fact that the distance from the source of the sound to the left ear is a little longer than it is to the right ear. Therefore, the sound waves must travel a little longer before reaching the left ear which is farthest away.
The brain registers the time lag and informs us that the direction of the sound is a little to the right of the face.
