F
The Correct Answer and Explanation is:
The correct answer is F (False).
Explanation:
Resonance does not occur primarily in the middle ear; it occurs in the outer ear and the ear canal, as well as in the eardrum (tympanic membrane) and structures within the middle ear that help amplify sound. To clarify:
- Resonance in the Outer Ear and Ear Canal:
Resonance refers to the amplification of sound waves at particular frequencies due to the physical dimensions of a space. In the case of the ear, the external auditory canal (the ear canal) acts as a resonating chamber. The ear canal’s shape and size enhance certain frequencies of sound, particularly those in the speech range (around 3,000 Hz), which is important for hearing human speech. - Role of the Middle Ear:
The middle ear contains the ossicles: the malleus (hammer), incus (anvil), and stapes (stirrup). These bones do not participate in resonance but instead play a crucial role in transmitting sound vibrations from the eardrum to the inner ear. The vibrations from the eardrum are amplified by the ossicles and sent to the oval window, which leads to the inner ear. - Resonance in the Inner Ear:
The inner ear, specifically the cochlea, is where sound vibrations are transformed into neural signals for the brain. The cochlea has a spiral shape that allows it to respond to different frequencies, but this is not resonance in the middle ear itself.
In summary, while resonance enhances sound perception, it occurs in the outer ear (ear canal) and not within the middle ear, where mechanical transmission of sound takes place through the ossicles.
