Sounds are heard when vibrations from an object...
- A Enter the ear and travel along tubes into the brain
- B Echo close to the eardrums causing impulses to be carried by nerves to the brain
- C Cause the eardrums to vibrate and impulses to be carried by nerves to the brain
- D Are reflected by the eardrums causing impulses to be carried by nerves to the brain
That's Correct!
It's Wrong!
When sounds are produced, they cause the eardrums to vibrate. These vibrations are then transmitted through the middle ear bones to the inner ear. In the inner ear, the vibrations are converted into electrical impulses by the hair cells. These impulses are then carried by the auditory nerve to the brain, where they are processed and interpreted as sound.
