10 Questions
What is the significance of the notch at 8kHz in vertical localization?
Indicates the sound is above your head
How does the presence of energy at 6kHz and 8Hz help in determining the origin of the sound?
Indicates the sound came from above the listener
What role does the pina play in sound localization?
Allows distinguishing sound from up or down
What are the four main functions of the middle ear?
Selective oval window stimulation, pressure equalization, protection, impedance matching
What happens if the middle ear is absent in the process of sound transfer to the oval window?
Loss of 40dB
What is the appearance and flexibility of the ear drum?
Looks like a ring, can move about 55mm out of 90 mm^2
What happens if there are fluids in the middle ear during sickness?
Loss of hearing
Describe the role of the concha in the ear.
Amplification of sound
Explain the process of direct air conduction in the middle ear.
Occurs only when oval and round windows are out of phase
What is the primary purpose of the middle ear muscles in protection?
Reduces gain of middle ear against loud sounds
Test your understanding of vertical localization and HRTF concepts by identifying the characteristics of sound based on notch frequencies and energy levels at specific frequencies. Learn how the brain processes sound cues to determine the height of noisy sounds.
