Hearing Quiz

What are the qualities of sounds that the auditory system picks up?

• Frequency, Intensity, Duration, Texture

• Frequency, Intensity, Duration, Location

• Pitch, Loudness, Duration, Location

• Pitch, Loudness, Duration, Texture

What is the function of the thalamus in the hearing process?

• It processes harmony, rhythm, and melody

• It is the brain's relay station for incoming sensory information

• It maintains the frequency map generated by the hair cells

• It converts sound waves into electrical signals

Which part of the brain is typically responsible for understanding and producing speech?

• Right auditory cortex

• Left auditory cortex

• Brainstem

• Thalamus

What happens when the membrane in the cochlea moves up and down?

• It excites the auditory nerve, which sends its electrical signals on to the brainstem

• It opens small channels in the hairs, allowing ions in the surrounding fluid to rush in and convert the physical movement into an electrochemical signal

• It converts the liquid motion into electrical signals that travel on to the brain

• It ripples the fluid inside the cochlea

What is the function of the basilar membrane in the cochlea?

• It is 'tuned' along its length to different frequencies, or pitches

• It processes harmony, rhythm, and melody

• It maintains the frequency map generated by the hair cells

• It is the brain's relay station for incoming sensory information

What is the role of the hair cells in the cochlea?

• They respond most strongly to just a narrow range of sound frequencies

• They convert the physical movement into an electrochemical signal

• They maintain the frequency map generated by the hair cells

• They convert the liquid motion into electrical signals that travel on to the brain

What is the function of the three tiny, sound-amplifying bones in the middle ear?

• They convert the liquid motion into electrical signals that travel on to the brain

• They vibrate in response to the sound waves and transmit that motion to the eardrum

• They are responsible for understanding and producing speech

• They are 'tuned' along their length to different frequencies, or pitches

What is the function of the eardrum in the hearing process?

• It processes harmony, rhythm, and melody

• It is the brain's relay station for incoming sensory information

• It vibrates in response to the sound waves and transmits that motion to the three tiny, sound-amplifying bones in the middle ear

• It converts sound waves into electrical signals

What is the function of the oval window in the hearing process?

• It is responsible for understanding and producing speech

• It is the brain's relay station for incoming sensory information

• It is a membrane separating the air-filled middle ear from the inner ear

• It is 'tuned' along its length to different frequencies, or pitches
