The Hearing Song: How Hearing Works - it’s CRAZY!

The video explains the process of hearing, starting with sound waves entering the ear and causing the eardrum to vibrate. These vibrations are transferred to the middle ear, where the ossicles amplify them. The vibrations then move to the inner ear, where the cochlea and basilar membrane play a crucial role. The organ of Corti converts these vibrations into electrical signals, which travel through the auditory nerve to the brain, allowing us to perceive sound.

What is the initial effect of sound waves on the ear?

• They directly stimulate the brain.

• They bypass the tympanic membrane.

• They make the eardrums vibrate.

• They are absorbed by the Eustachian tube.

Which part of the ear contains the ossicles?

• Inner ear

• Middle ear

• Outer ear

• Eustachian tube

What is the role of the cochlea in hearing?

• It filters out background noise.

• It protects the eardrum.

• It amplifies sound waves.

• It converts vibrations into neural signals.

Where are the hair cells located that are crucial for hearing?

• In the tympanic membrane

• In the Eustachian tube

• In the auditory cortex

• In the organ of Corti

How are auditory signals processed in the brain?

• They are sent to the visual cortex.

• They are processed in the auditory cortex.

• They are amplified.

• They are ignored.
