How are sounds of different pitch differentiated in the cochlea?
Pitch discrimination results from the fact that the basilar membrane has different vibrational properties along its length, such that the base (nearest the oval window) vibrates most strongly to high frequency sounds, and the tip to low frequencies.
Place theory describe the effect different tones have on the?
cochlea
How does the cochlea work?
The cochlea is responsible for hearing and is filled with fluid. When the oval window vibrates the fluid in the inner ear moves around. The membrane inside the cochlea has different levels of thickness and the vibrations have different frequency and correspond to different pitches of sound that the ear interprets. The oval windows vibration frequency is transmitted through the fluid wave within the inner ear. The fluid crosses over the membrane, depending on the frequency and stimulates nerves that transmit a signal to the brain.
How do different pitches affect the cochlea?
Different pitches vibrate the cochlea at different places
Describe the location and function of the eardrum and the cochlea?
the eardrum is in the middle ear and the cochlea is in the inner ear
What part of the cochlea is affected by the bass singer?
high frequency sounds at base of cochlea. encounter sound first and deteriorate first
How does humans perceive changes in frequency?
cochlea of ear perceive and respond to various frequencies in sound...
Where is the basilar membrane most sensitive to the vibrations of very high-frequency sound waves?
closest to the cochlea
How does the cochlea of the inner ear help you hear?
The cochlea has hairs cells that ride on the basilar membrane. These hair cells convert the mechanical vibration of sound waves into an electrical signal and excite the auditory nerve's 30 000 fibers. The auditory nerve transports the signal to the brainstem. Since each hair cell is on a different part of the basilar membrane, each hair cell is best excited by a different frequency. Thus, each nerve fiber carries auditory information about a different frequency to the brain.
What part of the inner ear is spiral shaped?
cochela Cochlea
Hair cells that enable us to distinguish the high frequency sound of a whistle from the low frequency sound of a tuba are found in what structure of the ear?
They are located in the spiral organ (organ of Corti). This structure is located in the cochlea.
What contains the cochlea?
the cochlea contains bone
