Sound Energy II - JSS3 Basic science Past Questions and Answers - page 2
What is the role of hair cells in the cochlea?
Hair cells in the cochlea convert sound vibrations into electrical signals that are sent to the brain for interpretation.
How does the auditory nerve contribute to the process of hearing?
The auditory nerve interprets electrical signals generated by the hair cells in the cochlea and transmits them to the brain, allowing us to perceive sound.
Why is understanding sound reflection important in everyday life?
Understanding sound reflection helps in designing spaces with optimal acoustics, such as concert halls, classrooms, and recording studios, ensuring clear and balanced sound distribution.
What happens when sound waves strike a surface?
Sound waves bounce off the surface, a phenomenon known as sound reflection. The angle at which they strike determines the angle at which they reflect.
How does the eardrum contribute to the process of hearing?
The eardrum vibrates in response to sound waves, transmitting these vibrations to the middle ear's tiny bones, which then amplify and transmit them to the cochlea for further processing.
The eardrum vibrates in response to sound waves, transmitting these vibrations to the middle ear's tiny bones, which then amplify and transmit them to the cochlea for further processing.
Sound vibrations cause the eardrum to vibrate, initiating the process of hearing by transmitting these vibrations through the middle ear to the cochlea in the inner ear.
