The basilar membrane a. has a place code for frequency. BOTH A AND C 11. Immediately after the sound wave reaches the basilar membrane, acoustic energy is a. converted into neural impulses that travel to the brain. Imagine that you put a pair of headphones on an owl and played the sound so that it is heard earlier on the left side and is louder on the right. The two sine waves on the right differ in their a. amplitude.
Humans can perceive the difference between two sine waves that differ only in phase.
Sound can travel in a vacuum a. because a vacuum is a suitable medium for sound to pass through. Imagine that you put a pair of headphones on an owl and played the sound so that it is heard earlier on the right side and is louder on the right. The spiral ganglion neuron receives neurotransmitter from a hair cell if you a. depolarize the hair cell. This is nonsense, the spiral ganglion neuron releases neurotransmitter onto the hair cell. In the barn owl, the preaural flap a. is located in slightly different places on the left and right sides.
