How does the amplitude of sound waves influence hearing sensitivity?.
Model answer
What a good answer should say
- The amplitude of sound waves influences hearing sensitivity by determining the loudness of the sound perceived by the ear.
- Higher amplitude sounds are detected more easily by the hair cells in the cochlea, leading to better hearing sensitivity at those amplitudes.
Explanation
Why this works
This answer effectively connects the cause (amplitude of sound waves) to the mechanism (detection by hair cells in the cochlea) and states the effect (increased loudness perception), highlighting the consequence of improved hearing sensitivity at higher amplitudes.
