Understanding the Hearing Process

What initiates the process of hearing?

• Electrical signals

• Sound waves

• Magnetic fields

• Light waves

What is the primary function of the pinna?

• To convert sound into electrical signals

• To produce sound

• To focus sound waves into the ear canal

• To vibrate in response to sound

Which part of the ear is also known as the tympanic membrane?

• Oval window

• Pinna

• Eardrum

• Cochlea

What are the three tiny bones in the middle ear called?

• Hammer, Anvil, and Stirrup

• Malleus, Incus, and Stapes

• Cochlea, Pinna, and Eardrum

• Oval window, Basilar membrane, and Hair cells

What is the role of the oval window in hearing?

• To produce sound waves

• To convert sound into electrical signals

• To transmit vibrations to the cochlea

• To amplify sound

What structure in the cochlea is responsible for detecting sound frequencies?

• Tympanic membrane

• Pinna

• Basilar membrane

• Oval window

How does the basilar membrane respond to different sound frequencies?

• It only vibrates for high frequencies

• It vibrates uniformly regardless of frequency

• It does not vibrate

• It vibrates at different locations depending on the frequency

What type of cells in the cochlea send signals to the brain?

• Hair cells

• Blood cells

• Skin cells

• Bone cells

Where in the brain are auditory signals interpreted?

• Frontal lobe

• Parietal lobe

• Occipital lobe

• Temporal lobe

What information does the brain use to determine the loudness of a sound?

• The color of the sound

• The speed of the sound

• The amount of vibration

• The direction of the sound
