The eardrum is __________ the oval window, which causes vibrations in the fluid of the cochlea. This is biologically adaptive because it __________.
A) 20 times smaller than; protects the eardrum from excess pressure
B) 20 times larger than; amplifies the physical stimulus
C) roughly the same size as; transmits the appropriate proximal stimulus to the receptors
D) similar in shape to; transmits high-amplitude waveforms to the cochlea

Question

Quizplus · Accepted Answer

The eardrum is significantly larger than the oval window, which helps in amplifying the sound waves that are transmitted to the cochlea, making it easier for the inner ear to detect these sounds. This amplification is crucial for the sensitive detection of a wide range of sound intensities.
