Consider the following statements.
i) Ears help our brain to sense from which directions the sounds are coming.
ii) Eustachian tubes equalize the air pressure on either side of the eardrum.
Both statements are true
If both ears are working well, sound waves hit both ears simultaneously which helps the brain to determine the direction of the sound. The eustachian tube extends from the middle ear to the nasopharynx, permitting air to enter or leave the middle ear cavity. Its function is to equalize air pressure on both sides of the eardrum. Hence, both the statements are true.
