10 Questions
What are the two parts of the inner ear?
Cochlea and vestibular apparatus
What are the two reasons why sound on one side of the head sounds louder for the near ear than the far ear?
Spreading loss and head diffraction effect
What is the function of the outer ear structures like pinna, concha, and external ear canal?
Protection, amplification, and sound localization
What is HRTF used for in the context of sound localization?
Head Related Transfer Function is used to create a 3D sound field by inverse Fourier transformation.
What is the role of pinna in sound localization?
Directional receiver for specific frequencies
How can a Click test help in vertical sound localization?
A Click test can determine if the sound is above your head by observing a significant notch at around 8kHz.
What is the range of frequencies that the ear canal amplifies?
1k to 7k Hz
What is the function of the pina in sound localization?
The pina helps in distinguishing whether the sound is coming from above or below.
Where does the standing wave phenomenon occur in the outer ear?
Concha and external ear canal
What role does the middle ear play in transferring sound energy to the oval window?
The middle ear mechanically transfers sound energy to the oval window for further processing.
Explore the anatomy and functions of the inner and outer ear, including the cochlea, vestibular apparatus, pina, concha, and external ear canal. Learn about the Place theory that links pitch perception to the stimulation of the cochlea's membrane.
