Question 10

What is stereoscopic hearing?

Answer 10

Stereoscopic hearing is the hearing of sounds from the surroundings with two ears

Question 11

What is the function of stereoscopic hearing?

Answer 11

Enable us to determine the direction of the sound accurately

Question 12

How do we determine the direction of the sound accurately with stereoscopic hearing?

Answer 12

The ear nearer to the source of the sound receives a stronger stimulus. It also receive the sound earlier than the other ear.
Therefore, the impulses from this ear reaches the brain earlier than the impulse from the other ear.
The brain interprets these two different impulses. It is able to determine the direction of sound.

Question 13

What is the advantage of animals having stereoscopic hearing?

Answer 13

Detect the presence of prey and predators more quickly
